Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a road. Output power regulation of wind turbines [Prior Art] Many of the developers in the current world are facing serious energy shortages, so they have invested in the research and development of green energy.谙中妒番适刹田η The green energy is the natural energy source, such as solar energy, tidal energy, annual energy and wind energy. In particular, the use of wind energy, because wind resources are easy to obtain 'because the power generation unit can be set anywhere, the development of wind power platform has become the primary option for green energy production. Wind turbines are mainly driven by a blade group and a speed change. The box, a generator and an electric energy converter constitute 'the blade group is combined with the variable box, and the gearbox is combined with the generator, the output electrical connector of the generator. Thereby, when the wind turbine of the wind turbine is driven by the wind energy, the two-blade group drives the gearbox to rotate, and the generator rotates in a variable speed due to the combination with the gearbox. At this time, the generator will rotate. The mechanical energy transfer energy is output to the power converter, and the conversion of the power converter generates a stable power, which is supplied to a load or incorporated into the commercial power. However, in general, the above-mentioned wind power generator has the following disadvantages when it is used to connect the utility power: 201136090 1. Damage of the energy storage component of the power converter: During the energy conversion process, the wind power generator needs to perform power management. Therefore, the power converter needs to set components such as a storage capacitor and a battery. Since the energy source of the wind generator is derived from wind energy, when the external wind energy is too large, the converted electrical energy exceeds the maximum capacity of the energy storage component. The limitation causes an overcharge condition, which will result in damage to the ship components of the electric energy service or shorten the service life of the energy storage element. 2. The islanding effect causes damage to the wind turbine: Since the wind turbine is simultaneously connected to the load and the mains system, the load or the mains system needs to be repaired by the equipment and is powered off, due to the relationship between the external winds The motor continues to operate, but at this time the wind turbine generates the amount that cannot be sent to the mains, thus causing the wind turbine to easily exceed its maximum rated speed and cause damage. Based on the above, it is necessary to further improve the above disadvantages such as the wind turbine. SUMMARY OF THE INVENTION The main object of the present invention is to provide an output power adjustment circuit for wind power generation in parallel mains to improve the energy storage component of the power converter. The secondary object of the present invention is to provide an output power circuit for a wind power generator that is connected in parallel to avoid wind damage caused by an islanding effect. According to the present invention, an output power vocal circuit for a wind power generation of a parallel mains includes an electric energy wheel, a power wheel, and a power adjustment. The 201136090 group ^the Wei wheel and the electric wheel are mutually Connected, the power transmission system is connected to the stator-generator-stator coil, and the power output bee is supplied to an energy storage unit and the electric energy is turned; the power adjustment component includes a start switch and an adjustment resistor. And the adjusting resistor is connected in series with each other, and the series circuit formed by the starting switch and the adjusting resistor is connected in parallel with the electric circuit b, and the starting switch of the power adjusting component is controlled by the external control signal to form an on state. The power adjustment component is used to adjust the power between the generator and the ship unit domain power (four). [Embodiment] The above-mentioned other objects, features and advantages of the present invention will become more apparent and obvious. The following detailed description of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing the circuit connection of a wind power generation unit 1, an output power adjustment circuit 2, an energy storage unit 3, and an electric moon b converter 4 according to the first embodiment of the present invention. The above unit constitutes a wind power generation system which supplies a load of electrical energy and operates in parallel with a mains system. The wind power unit 1 includes a blade group U, a gearbox 12, and a generator 13. The fan blade group π can drive the gearbox 12 to rotate when driven by the wind energy, and drive the generator 13 to rotate at a higher rotation speed, so that one of the stator coils 131 of the generator 13 induces a current, and the current is The stator coil 131 is outputted.

The power conditioning component 23 is connected in parallel to the power. The power adjustment component 23 further includes a start switch & ===:=the start switch 231 is in series with the adjustment resistor == series connection 'the start switch 231 and the regulation = the power output 槔22 in parallel; the start switch 231 series = = switch (such as relay) or - electronic τ and = : open, in response to frequent switching operations, relatively close, the role of the regulating resistor 232, 々 electric thousand-type electric energy conversion H 4 face, so ' The lowering of the energy storage unit 3 and the small rated resistance, for example, the adjusting resistor 232 is preferably a regulating resistor 232 because of the resistance of the two ohm resistance value and the resistance, the high power resistor has a high power rate The amount of resistance generated by the resistor can be difficult to make a heat sheet 'so that a large current passes through the high-power, please refer to the two heat sinks for heat dissipation. As shown in Fig. 1, the start switch 231 of the component 23 of the first embodiment of the present invention is connected to a controller 5 for detecting a DC input voltage of the power converter 4, and The start switch 231 is controlled to be turned on or off according to the flow input voltage. ^ When the generator 13 of the wind power generation unit 1 converts current due to the rotation of the blade stage, and charges and supplies the energy storage unit 3 and the power converter 4, the controller 5 detects the DC The input voltage does not reach the ancient maximum fixed upper limit voltage. At this time, the start switch 231 is controlled to form a disconnected state = ^ In this case, the current converted by the generator 13 of the wind power generation unit i continues to the energy storage unit. 3 and the power converter 4 is powered. The above control method is based on the following theoretical analysis: when the generator 13 is in a stable operating condition, it can be obtained by electromagnetic theory analysis, the output voltage of the generator 13 is proportional to the rotational speed, and, due to the output of the generator 13 The current is proportional to the reaction torque generated by the generator 13, so that its output current is also proportional to the size of the outside wind. The fan blade group 11 of the wind power generation unit 1 continues to rotate, and the energy storage unit 7G 3 is charged so that the charging voltage continues to climb until the upper limit of the charging voltage is reached, so as to avoid the difficult unit 3 being overcharged. As a result of controlling the damage of H 5 , the controller 5 controls the start switch 231 to be in an on state at this time. Since the resistance value of the adjustment resistor 232 is relatively small compared to the energy storage unit 3 and the electric energy device H 4 , When the generator 13 cannot change the rotation speed immediately due to the inertia #, the output voltage of the generator U does not change immediately, and the output voltage of the generator is applied to the adjustment resistor 232. Therefore, the generator 13 The regulating resistor 232 will circulate a high-value current, so that the opposite side torque of the money 13 is instantaneously increased, thereby slowing down the speed of the wind power generation fan blade group π, 201136090, and the energy storage unit 3 and the power converter The voltage established on 4 is gradually decreased by 1 until the above-mentioned power is lower than the setting of the charging voltage of the energy storage unit 3, and the controller 5 controls the start switch 231 to form an open θ again. The power-regulating circuit 2 acts as the power of the power storage unit 3, the power converter 4, and the power source of the converter or the mains system of the converter. The output power adjustment circuit 6 of the second embodiment of the present invention also has an electric two-H power output bee 62 and a power adjustment component 63, and the component 63 also includes a start switch. 631 and - adjusting the resistor 5, the starting switch 631 of the assembly 63 is also for light connection. The components of the embodiment have the same circuit state as all the components of the wheeling adjustment circuit 2 of the first embodiment. In the first embodiment of the present invention, as shown in the first embodiment of the present invention, the output power adjustment circuit 6 of the young woman J further includes a supplemental cow. 64, comprising: an auxiliary start switch 641 and an auxiliary adjustment power assist! The off 641 is connected to the auxiliary adjustment resistor 642 by the auxiliary start switch 641 and the auxiliary adjustment switch. The power wheel is connected in parallel with the 62 , the auxiliary switch (such as a relay) or - an electronic switch (such as τ 〇 〇 = = help start switch (4) instantaneously need to flow a large current, the auxiliary 641 is better to choose the relay. 阙 阙 201136090 One of the auxiliary adjusting resistors 642 adjusts the resistance of the electric energy converter 4. The auxiliary resistance value is much smaller than the resistance value of the resistance (4) of the auxiliary adjusting resistor (4): and the auxiliary adjusting value The better value between the resistance values of the electric # 4 H 1 32 = the resistance value of the resistor 632 is greater than - the preset value, ^: the resistance value of the auxiliary adjustment resistor 642 is ι〇 = , 642 is required to withstand a large current, and Select to set a high = 'The power resistor also has a heat sink for heat dissipation. The auxiliary adjustment resistor 642 is used to protect the: = * can not = = move =: electricity: the generator 13 changes due to inertia rotation, Instead, the output voltage of the motor 13 will not rise. ★ Therefore, the __ regulation resistor 642 will circulate - the height of the second high is higher than the resistance of the aforementioned adjustment resistor 642 (because the auxiliary operation, at this time, the speed of the motor is extremely low) 丄::== The low speed causes the power converter 4 to have an influence, so that the power can be prevented from causing damage to the generator 201136090 13 and the power converter 4 due to the islanding effect. The output power adjustment circuit 5 can further assist the power of the wind power generation unit 1 between the energy storage unit 3, the power converter 4, and the back end of the power converter 4 or the power system, wherein the controller 5 The controller 5 is connected to the auxiliary regulating power (4) 42 so that the controller 5' can detect the passing current of the auxiliary adjusting resistor 642, and the auxiliary The passing current of the withstanding resistor 642 is proportional to the reverse torque of the generator 13 . Once the circulating current on the auxiliary regulating resistor 642 is lower than the lower limit of the setting, the representative wind may have become smaller to the blade group 11 . Rotating speed Safe operating range 'At this time, the controller 5' controls the auxiliary starting switch 641 to open 'to increase the speed of the generator 13 to perform normal operation of the generator 13.
