Description

Generator distributed voltage regulation control system and method

technical field

The present application relates to voltage regulation control of generators, in particular to voltage regulation control of aircraft generators.

Background technique

Generator voltage regulating point voltage is an important index of power system. If the voltage requirement of the voltage regulating point of the generator is too high, the output power of the generator will be increased, resulting in waste of energy, and at the same time, higher requirements are placed on the installed capacity of the generator; Increase the difficulty of designing the electrical system. Therefore, a reasonable generator voltage regulation voltage requirement can optimize the power system.

The existing aircraft performs voltage regulation control near the generator output, and conservatively estimates the line voltage drop. In order to ensure the normal operation of the equipment, the voltage regulation point is often set at a higher voltage, resulting in a large number of equipment working at a higher input voltage. .

The airborne equipment is distributed in different positions of the whole machine. Due to the voltage division of the cable, the voltage at the equipment end will be lower than the voltage of the voltage regulation point. For example, under the 115V power supply system, the POR terminal voltage of the generator is usually required to be at least 113.5V, while the operating voltage requirements for equipment in DO 160 are: the equipment should work normally when it is not lower than 101.5V. Under such a control strategy, a large number of devices will work at a higher voltage and consume more energy.

Aircraft high-power loads are usually mainly resistive loads and motor loads. Resistive loads usually consume more energy when the input voltage is higher, while motor loads are usually designed to operate at the lowest The output efficiency is the highest in the normal working voltage range, and in the case of higher voltage, more reactive power will be generated, which will cause great waste of energy.

In order to effectively utilize aircraft power resources, a more efficient generator voltage regulation control system and method are required.

Detailed ways

In order to make the above objects, features and advantages of the present disclosure more comprehensible, specific implementations of the present disclosure will be described in detail below in conjunction with the accompanying drawings.

Many specific details are set forth in the following description to facilitate a full understanding of the present disclosure, but the present disclosure can also be implemented in other ways than those described here, so the present disclosure is not limited by the specific embodiments disclosed below.

The power grid of large aircraft has large capacity and many electrical equipment, so AC power is used as the main power supply. However, according to airworthiness requirements, a DC power supply system must be provided at the same time, so the power supply network is relatively complicated.

The structure of the power supply network of different types of aircraft is different. For example, a narrow body aircraft may have only a primary bus bar, a wide body aircraft (such as an A350) may have a secondary bus bar, and a larger aircraft may have a tertiary bus bar.

According to the importance of power supply equipment, for example, a large aircraft has three levels of bus bars: normal bus bar, important bus bar and emergency bus bar. Normally, the equipment whose loss does not affect the flight safety of the aircraft is powered by the normal busbar (for example, kitchen electrical equipment, cabin entertainment system, side windshield heating, etc.), and the loss of equipment will have a negative impact on the safe operation and landing of the aircraft. Affected ones usually adopt redundant power supply mode, using dual redundant power supply of normal bus bar and important bus bar (for example, engine indicating instrument, anti-collision light, inertial navigation platform, etc.) Other power supply means supply power to the equipment that guarantees the minimum functions of the aircraft and safe landing (for example, communication, cockpit control, environmental control, flight control computer, etc.).

As shown in Figure 1, the existing aircraft usually sets the voltage regulation point 102 between the generator output terminal 104 and the AC bus bar 106, uses the signal detection module to collect the output voltage characteristics of the generator, and feeds back to the generator voltage regulation controller 108 , by adjusting the excitation, the voltage of the voltage regulating point is controlled within a certain range. This regulation point is located at the engine output 104 and is a single regulation point.

The above existing technical solution enables the existing aircraft to perform voltage regulation control near the output end of the generator, and perform conservative estimation on the line voltage drop. In order to ensure the normal operation of the equipment, the voltage regulation point is often set at a higher voltage, resulting in a large number of equipment working at a higher input voltage; the high-power loads of the aircraft are usually mainly resistive loads and motor loads, and resistive loads usually input voltage The larger it is, the more energy it consumes. In order to ensure the performance within the normal operating voltage range, motor loads are usually designed to have the highest output efficiency within the lowest normal operating voltage range. Too much reactive power will cause a great waste of energy. According to statistical calculation, 5% of the load of the whole machine consumes 90% of the energy of the whole machine.

Therefore, for the aircraft power supply network with multi-level bus bars, this disclosure intends to reduce the energy consumption of airborne equipment by performing distributed and dynamic global precise voltage regulation control on the equipment side of the high-power load of each level of bus bars.

Fig. 2 shows a block diagram of a distributed generator voltage regulation system 200 according to an embodiment of the present disclosure. The distributed generator voltage regulation control system 200 transfers the voltage regulation point of the generator from the output end of the generator to the input end of the high-power equipment, uses the distributed voltage regulation point to realize precise voltage regulation control, and makes the aircraft load work at The state with the highest output efficiency.

The distributed voltage regulation control system 200 includes a signal acquisition module 202 , a signal transmission module 204 and a voltage regulation controller 206 . Wherein, the signal acquisition module 202 and the signal transmission module 204 can be integrated together, or can be independent of each other.

The signal collection module 202 is used to collect the voltage signal of the load at the load input terminal. In an embodiment of the present disclosure, the signal collection module 202 collects a voltage signal of the high-power load at an input end of the high-power load. This is taken into consideration for load distribution on the aircraft. It can be seen from statistical data that 5% of the high-power load of the whole machine consumes 90% of the energy of the whole machine. Resistive loads in high-power loads consume more energy when the input voltage is higher, and motor loads in high-power loads are usually designed to operate within the lowest normal operating voltage range in order to ensure performance within the normal operating voltage range. The output efficiency is the highest, and it will generate more reactive power when the voltage is higher. Therefore, the distributed voltage signal collection of high-power loads on different levels of bus bars is beneficial to accurately determine the appropriate voltage regulation point, thereby reducing the energy consumption of airborne equipment.

Further, the distributed generator voltage regulation control system 200 can use a dynamic global voltage regulation control method to adjust the voltage regulation control method according to the load change at any time. Specifically, in different flight phases of the aircraft, the main work load of the aircraft will change, and the distributed generator voltage regulation control system 200 of the present disclosure can dynamically select the optimal voltage regulation point according to the load characteristics for accurate Regulate.

In another embodiment of the present disclosure, the signal collection module 202 collects the voltage signal of the load at the load input terminal at the beginning of different flight stages. For example, in the ground service phase (or ground maintenance phase, etc.), the loads of the aircraft are mainly resistive loads, and the load voltage signals collected by the signal acquisition module 202 are mainly concentrated on these resistive loads.

The signal transmission module 204 is used to transmit the collected signal to the voltage regulating controller 206 . Those skilled in the art can understand that, in an embodiment of the present disclosure, when performing dynamic global voltage regulation control, the signal transmission module 204 can send a trigger signal for the start of the flight phase to the signal acquisition module 202, so that the signal acquisition module Step 202 performs a new round of distributed load voltage signal collection.

The voltage regulating controller 206 includes functions of signal screening and logic judgment, and controlling the intensity of the magnetic field. The voltage regulation controller 206 processes the received distributed voltage regulation point signal, and screens the processed distributed voltage regulation point signal; then uses the filtered voltage regulation point signal as the feedback input of the magnetic field strength control, The output voltage of the generator is adjusted to form a closed-loop control. How the voltage regulation controller 206 processes and screens the voltage regulation point signal will be further described in detail below with reference to FIG. 4 and FIG. 5 .

The disclosure realizes refined control on the terminal voltage of the electrical equipment, reduces the energy consumption of the equipment, saves fuel, and at the same time, reduces the impact current of the motor load, and prolongs the service life of the equipment.

FIG. 3 shows a distributed generator voltage regulation system architecture 300 according to an embodiment of the present disclosure.

As shown in Figure 3, the traditional single voltage regulation point located at the output end of the generator is adjusted to the input end of the high-power equipment to form a distributed dynamic voltage regulation control system architecture.

In the distributed generator voltage regulating system architecture 300 with multi-level bus bars, the signal acquisition module 202 is installed at the input end of the high-power load as close as possible to the load. That is to say, each voltage regulating point is respectively set at a position as close as possible to the input end of the high-power load on the bus bars of each level.

That is, the input end of load 1 under the primary bus bar 302 is provided with a voltage regulation point 1, the input end of load 2 is provided with a voltage regulation point 2, ..., and the input end of load K is provided with a voltage regulation point K. The input end of the load 1 under the secondary bus bar 304 is provided with a voltage regulation point 1, the input end of the load 2 is provided with a voltage regulation point 2, . . . , and the input end of the load M is provided with a voltage regulation point M. The input end of the load 1 under the three-stage bus bar 306 is provided with a voltage regulation point 1, the input end of the load 2 is provided with a voltage regulation point 2, . . . , and the input end of the load N is provided with a voltage regulation point N. The voltage signals of multiple load devices collected at these voltage regulation points can form a load terminal input voltage set.

The voltage regulator controller 206 initially screens the received voltage signal. In an embodiment of the present disclosure, a voltage regulating point is screened for a structure of multiple levels of bus bars. In another embodiment of the present disclosure, a voltage regulating point may be selected for each of the multiple levels of bus bars to control the corresponding generators in stages. Those skilled in the art can understand that the screening of the voltage regulation point of different models can be carried out according to different standards; equipment), the voltage ranges of their reference voltage regulation points are different. The technical solution disclosed in the present disclosure can be adapted for various models and different types of airborne equipment, and precise voltage control is performed by collecting the voltage of voltage regulation points in a distributed manner.

Then the voltage regulation controller 206 controls the magnetic field of the generator based on the screened voltage regulation points, thereby adjusting the output voltage of the generator to form a closed-loop control.

Thus, the technical solution disclosed in the present disclosure realizes real-time globally optimized voltage control, thereby ensuring that the input terminal voltage of all devices meets the minimum operating voltage requirements of the device, so that most loads, especially resistive loads (such as lamps) and motor loads (such as hydraulic pumps) work within the minimum normal working voltage range, reduce the energy consumption of the equipment, and when the high-power motor load is powered on, reduce the inrush current, protect the load, prolong the service life of the equipment, and reduce the use cost of the airline .

Fig. 4 shows a flowchart of a distributed generator voltage regulation method 400 according to an embodiment of the present disclosure.

At 402, a voltage signal of a load is collected at an input terminal of the load.

As mentioned above, existing aircraft have voltage regulation control near the output of the generator and a conservative estimate of the line voltage drop. This will cause the high-power load of the aircraft to consume more energy when the input voltage is greater, thereby causing excessive energy consumption of the equipment.

Therefore, the present disclosure adopts a distributed voltage regulation method for the aircraft generator, that is, the voltage regulation point is transferred from the output end of the generator to the input end of the load, especially the input end of the high-power load.

At 404, the collected voltage signals are formed into a voltage signal set.

At 406, each voltage signal in the set of voltage signals is compared to the lowest operating voltage of the corresponding load. Those skilled in the art can understand that the comparison may adopt different comparison methods for different aircraft equipment.

At 408, a trim point is screened based on the comparison.

In an embodiment of the present disclosure, the comparison result may be preprocessed, and then the pressure regulation point may be further screened out. In another embodiment of the present disclosure, the pressure regulation point can be directly screened out.

It is worth noting that the selection of voltage regulation points here can be optimally selected according to the load characteristics.

At 410, the magnetic field control of the aircraft generator is performed based on the screened voltage regulation points, so as to adjust the output voltage of the aircraft generator.

After the voltage regulating point is selected, the magnetic field inside the generator can be adjusted so that the input terminal voltage of the device is close to the minimum input voltage of the device.

Then detect the input terminal voltage of other equipment, monitor the status of the equipment in the circuit at any time, and perform a new round of logical judgment to ensure that the input terminal voltage of all equipment that should work normally remains within the normal operating range during the voltage regulation process.

Therefore, the distributed generator voltage regulation method of the present disclosure makes the related equipment work at the lowest normal working voltage by controlling the terminal voltage of the equipment, reduces the energy consumption of the equipment, and saves fuel; by controlling the terminal voltage of the equipment, it can also reduce The inrush current of the motor load prolongs the life of the equipment.

Fig. 5 shows a flowchart of a distributed generator voltage regulation method 500 according to another embodiment of the present disclosure.

Using the distributed generator voltage regulation method 500 for voltage regulation can realize the energy-saving design of resistive equipment and fuel pumps, and at the same time, can reduce the starting inrush current of electric pumps and other motor equipment.

At 502, a detection voltage set input is received.

The disclosure adopts a distributed voltage regulation method for aircraft generators, that is, the voltage regulation point is transferred from the output end of the generator to the input end of the load, especially the input end of the high-power load. The high-power loads of aircraft are usually mainly resistive loads and motor loads.

In an embodiment of the present disclosure, the voltage signal of the high-power load can be collected in a distributed manner at the input end of the high-power load on the multi-level bus bar. In another embodiment of the present disclosure, the voltage signal can be collected correspondingly according to the characteristics of the loads used in different flight stages. For example, only acquire the input terminal voltage signal of the load on the main working bus. Those skilled in the art can understand that for different types of aircraft, the voltage signal of the load can be flexibly collected at the input end of the load according to the different architectures of the power supply system, thereby receiving the detection voltage set input.

At 504, calculate the difference δV between each voltage signal in the voltage signal set and the lowest operating voltage of the corresponding load to obtain a δV set.

In an embodiment of the present disclosure, the calculation may be to subtract the minimum operating voltage of the device from the collected voltage to obtain a difference δV between the voltage at the input terminal of the device and the minimum operating voltage of the device, and further form a δV set. in:

δV = equipment input terminal voltage - equipment minimum operating voltage

The minimum operating voltage for this equipment is that specified in DO-160 or the equipment specification.

In another embodiment of the present disclosure, the calculation may be to subtract the minimum operating voltage of the device and a safety margin from the collected voltage to obtain a difference δV, and further form a δV set. in:

δV = input terminal voltage of equipment - (minimum operating voltage of equipment + safety margin)

Those skilled in the art can understand that the calculation may adopt different calculation methods for different aircraft equipment.

At 506, the set of difference values δV is preprocessed.

At 508, the device-side delta V value for the delta-V concentrating device open circuit is discarded.

That is, if δV is equal to the negative rated voltage (eg 30V) ± allowable measurement error, the value should be discarded.

Next, at 510, detect whether there is a short circuit fault in the circuit, if there is a short circuit fault, maintain the original excitation current, and wait for the short circuit fault to be isolated; after the short circuit is isolated, re-detect the input terminal voltage of all devices.

Then, at 512, if there is no short-circuit fault, it is checked whether the generator works normally.

In an embodiment of the present disclosure, it is detected whether there is a value less than 0 in the δV concentration; if there is a value of δV less than 0, then increase the magnetic field strength in the generator and increase the output voltage of the generator.

In another embodiment of the present disclosure, it is detected whether the concentration of δV is less than -3%V; if yes, the magnetic field strength in the generator is increased, and the output voltage of the generator is increased.

Thus, after the preprocessing of the comparison result is completed, that is, after the open circuit, short circuit, and abnormal operation of the generator are excluded, the voltage regulation point is further screened out at 514 .

It is worth noting that the selection of voltage regulation points here can be optimally selected according to the load characteristics.

In an embodiment of the present disclosure, the minimum value δV _min in the set of δV is screened out, and the input end of the device corresponding to this value is used as the voltage regulation point of the current generator output voltage.

In another embodiment of the present disclosure, the screening of pressure regulation points is performed according to different flight stages.

以供将该值对应的设备输入端作为当前发电机输出电压的调压点。For example, in the ground service mode, the working load of the aircraft is mainly resistive loads (such as lights, kitchens, bathrooms, cargo, etc.), which are not sensitive to voltage. At this time, the average value of the concentration equal to δV is selected

The input end of the device corresponding to this value is used as the voltage regulation point of the current output voltage of the generator.

For example, in cruise mode, the main working load of the aircraft is an electric motor type load such as a hydraulic pump. At this time, the concentration equal to δV is selected, and the input terminal of the equipment corresponding to this value is used as the voltage regulation point of the current generator output voltage.

也可结合具体负载工作情形来采用其它合适的策略。Those skilled in the art can understand that the optimal voltage regulation point screening scheme according to the load characteristics can be selected according to the load characteristics of different types of aircraft, and the minimum value δV _min or the average value of the δV set can be selected

Other appropriate strategies may also be adopted in combination with specific load working conditions.

At 516 , use the device input terminal corresponding to the selected δV as a voltage regulating point to regulate the magnetic field of the generator.

作为调压点In an embodiment of the present disclosure, the minimum value δV _min of the set of δV is selected as the voltage regulation point. In another embodiment of the present disclosure, the average value is filtered out

as a pressure point

It can be seen from the lower figure 604 in Figure 6 that the distributed generator voltage regulation implementation of the present disclosure can guarantee the energy-saving design of resistive high-power loads: due to the resistive characteristics of cabin lighting equipment, the higher the input voltage, the brighter the brightness. High, through the distributed voltage regulation control system, the input terminal voltage can be reduced to reduce energy consumption.
