Description

Method and device for calculating telemetry response time

technical field

The invention relates to the technical field of scheduling automation systems, and in particular, to a method and device for calculating telemetry response time.

Background technique

At present, in the dispatch automation system, the automatic voltage control (Automatic Voltage Control, AVC) function has become one of the key functional applications. The main function of the AVC function is to use the data acquisition and monitoring control system (Supervisory Control And Data Acquisition, SCADA) to collect the high reactive power of each substation and the 10kV bus voltage telemetry value, and to judge in real time whether the telemetry value is in a state beyond the limit. And through the automatic control of the main variable gear position and capacitor/reactor of each substation, the reactive power and 10kV bus voltage values are restored to the qualified range.

However, the AVC application in the dispatching automation system is extremely sensitive to the substation data collected by SCADA, especially the real-time value of the reactive power on the high side of the main transformer and the 10kV bus voltage. The accuracy of these two values directly affects whether the AVC application generates adjustment strategy, and what regulation strategy is generated. If the value is inaccurate or out of synchronization, it will directly lead to wrong judgment in the AVC application, generate wrong control strategy, and cause the substation voltage or reactive power to be over-limited and unable to be adjusted in time or even over-regulated. It will not only affect the qualification rate of the grid voltage operation, but also cause the grid voltage to fluctuate seriously, resulting in burnout and failure of electrical appliances.

However, in the daily automatic operation and maintenance analysis, when the communication channel between some substations and the main station is large, the substation has a large amount of telemetry data that needs to be sent to the main station. After the AVC controls the equipment in the station, the reactive power on the high side of the main transformer and the 10kV bus voltage cannot be updated in time. In this case, because the data is still out of limit, AVC will generate a new strategy to adjust again, resulting in over-regulation of the actual voltage or reactive power on site, affecting the actual voltage qualification rate.

Detailed ways

Embodiments of the present invention provide a method and device for calculating telemetry response time, which are used to ensure data synchronization of a scheduling automation system and ensure the stability and security of AVC operation.

In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flow chart of steps of Embodiment 1 of a method for calculating telemetry response time according to the present invention, which may specifically include the following steps:

Step S101, obtaining the adjustment control item information of the AVC application;

In the embodiment of the present invention, each gear adjustment and capacitor/reactor switch control operation of the AVC application is monitored to capture the information of each adjustment and control item. When it is determined that a control item appears in the control item information, that is, the gear position appears. After adjustment or capacitor/reactor switch control, start the calculation program.

Step S102, when the adjustment control item information is control, determine the control type;

Step S103, obtaining the rated parameter corresponding to the control type from the preset AVC database;

Specifically, the control types include: capacitor/reactor switch adjustment, and gear position adjustment; the rated parameters include: capacitor/reactor rated capacity, busbar adjustment sensitivity, and gear distance parameters; obtained from the preset AVC database The rated parameters corresponding to the control types include:

If the control type is capacitor/reactor switch adjustment, obtain the capacitor/reactor rated capacity of the target capacitor/reactor and the busbar adjustment sensitivity of the target segment busbar from the AVC database;

If the control type is gear adjustment, the gear parameters of the target main transformer are acquired from the AVC database.

In the embodiment of the present invention, if the control type is capacitor/reactor switch adjustment, the rated capacity of the target capacitor/reactor and the adjustment sensitivity of the corresponding bus are obtained from the AVC database preset in the system; If the type is gear adjustment, obtain the gear pitch parameters of the main variable in the AVC database.

It should be noted that the busbar adjustment sensitivity is the AVC adjustment parameter set in the AVC database, which represents the change value of the 10kV busbar voltage caused by the input or withdrawal of the unit capacity capacitance/reactance. If the capacity of a capacitor is 6MVar and the voltage adjustment sensitivity is 0.03, then when the capacitor is switched on or off, it is expected that the corresponding bus voltage will change by 6MVar*0.03=0.18kV. The voltage change is the product of the voltage regulation sensitivity and the capacitor capacity.

In addition, the span parameter can be understood as: the 10kV bus voltage change value caused by the first shift, if the span is 1.5%, it means that the first shift will cause the 10kV bus voltage to change by 10kV*0.015=0.15kV.

At the same time, the rise and fall of the gear position has almost no effect on the reactive power of the main transformer becoming higher, so it is not necessary to monitor the reactive power telemetry of the master transformer becoming higher when adjusting the gear position.

Step S104, obtaining the location of the telemetry object to be monitored and its telemetry value according to the topological connection relationship and the control type;

Specifically include:

According to the topological connection relationship, locate the location of the telemetry object to be monitored;

If the control type is the capacitor/reactor switch adjustment, obtain the 10kV busbar voltage value and the reactive power of the main transformer of the busbar connected to the target capacitor/reactor;

If the control type is gear adjustment, obtain the 10kV busbar voltage value of the busbar connected to the target main transformer.

In the embodiment of the present invention, after starting the calculation program, the AVC application generates a strategy and issues a command, so that the telemetry value that needs to be monitored in real time can be located according to the topology link relationship of the AVC application. If the adjustment object is a capacitor/reactor switch, the monitored telemetry value is the 10kV busbar voltage value connected to the capacitor/reactor and the reactive power of the main transformer connected to the busbar correspondingly; if the adjustment object is a gear, then The monitored telemetry value is the 10kV bus voltage value of the bus to which the target main transformer is connected.

Step S105, based on the telemetry difference between the telemetry value before the control and the telemetry value after the control, in combination with the preset sensitivity and the rated parameter, determine the type of change after the telemetry object is controlled; the change Types include: minor changes and significant changes;

Specifically, the preset sensitivity includes: adjusting the sensitivity and gear parameters; based on the telemetry difference between the telemetry value before the control and the telemetry value after the control, in combination with the preset sensitivity and the rated parameter, Determine the type of change after the telemetry object is controlled, including:

If the control type is the switch adjustment of the capacitor/reactor, then determine whether the voltage difference between the 10kV busbar voltage value of the busbar connected to the target capacitor/reactor before and after control is greater than the adjustment sensitivity and the capacitor/reactor voltage difference. The product of the rated capacity of the reactor; and, judging whether the power difference between the main transformer and the reactive power before and after control is greater than the preset percentage of the rated capacity of the capacitor/reactor; if so, determine the change type as Significant change; if not, determine that the type of change is a minor change;

If the control type is gear adjustment, determine whether the voltage difference between the 10kV busbar voltage value of the busbar connected to the target main transformer before and after control is greater than the product of the gear position parameter and 10Kv; if so, determine the change type is a significant change; if not, the type of change is determined to be a minor change.

In the embodiment of the present invention, the AVC application control service is monitored, the corresponding remote control success judgment is captured, and the time point when the gear adjustment is successful or the capacitance/reaction switch remote control is successful is obtained as the starting time, which indicates that the gear has been raised and lowered. Completed or when the switch has been opened/closed in place.

Then, in the process of monitoring the telemetry object and its telemetry value, when the telemetry value changes, record the 10kV busbar voltage value and voltage change time of the busbar connected to the target main transformer after the change, and the main transformer after the change. power and power change time.

Then, the significant change judgment mechanism is started to judge whether the change type is a significant change, specifically: if the control type is capacitor/reactor control, calculate the voltage difference, and compare the relationship between the voltage change value and the adjustment sensitivity, if the voltage If the difference is greater than 50% of the expected voltage change caused by the capacitor/reactor input or withdrawal, it is judged as a significant change. If the voltage difference is less than or equal to 50% of the expected voltage change caused by the capacitor/reactor input or withdrawal, Then it is judged as a slight change; then calculate the power difference between the main transformer and the reactive power before and after control, and compare the relationship between the power difference and the rated capacity of the capacitor/reactor. If the power difference is greater than 50% of the rated capacity of the capacitor/reactor. %, it is judged as a significant change, and if the power difference is less than or equal to 50% of the rated capacity of the capacitor/reactor, it is judged as a slight change.

If the adjustment control is gear adjustment, make the following judgment of significant voltage change: Calculate the voltage difference between the 10kV busbar voltage value of the busbar connected to the target main transformer before and after control, and compare the product of the voltage difference value and the gear position parameter and 10Kv. If the voltage difference is greater than the product of the gear parameter and 10Kv, it is judged as a significant change, and if the voltage difference is less than or equal to the product of the gear parameter and 10Kv, it is judged as a slight change.

Step S106, when the change type is the significant change, calculate the telemetry response time.

In the embodiment of the present invention, in general, the telemetry value will be continuously monitored until a significant change occurs, according to the time difference between the start time and the voltage change time as the telemetry response time for gear adjustment, and the start time and the voltage change The time difference is used as the response time of the control voltage in the capacitor/reactor switching adjustment, and the time difference between the start time and the power change time, as the response time of the main transformer becoming high reactive power.

In an optional embodiment, when the change type is the significant change, after calculating the telemetry response time, the method further includes:

The telemetry response time is stored in the AVC database, and the average telemetry response time is calculated in combination with the historical telemetry response time in the AVC database.

In the embodiment of the present invention, the regulated voltage or reactive telemetry response time of each AVC application is stored in the warehouse, and the average telemetry response time regulated by AVC in the same substation is calculated through a list and related statistics. It is convenient for dispatchers and automatic operation and maintenance personnel to analyze and monitor the corresponding characteristics of the AVC adjustment of the substation. If abnormal response time is found, it will be dealt with in time.

It should be noted that the method of the present invention mainly utilizes the corresponding relationship between the equipment in the AVC application of the scheduling automation system and the corresponding monitoring object to form the corresponding relationship between the AVC adjusting device and the corresponding monitoring telemetry point.

In the embodiment of the present invention, after the AVC generation strategy adjusts and controls the device, the calculation process is started, and the time corresponding to the successful remote control is recorded as the starting point, and then the AVC monitoring telemetry value of the target device is monitored in real time. After a significant change occurs, record the telemetry refresh time point as the record end point, and determine the telemetry response time by calculating the time difference between the start point and the record end point. In the embodiment of the present invention, the adjustment control item information of the AVC application is obtained; when the adjustment control item information is control, the control type is determined; the rated parameter corresponding to the control type is obtained from the preset AVC database; according to the topology The connection relationship and the control type, obtain the location of the telemetry object to be monitored and its telemetry value; based on the telemetry difference between the telemetry value before the control and the telemetry value after the control, combine the preset sensitivity and The rated parameter is used to determine the change type after the telemetry object is controlled; the change type includes: slight change and significant change; when the change type is the significant change, the telemetry response time is calculated. When it is determined that the change type of the telemetry object is a significant change, the corresponding telemetry response time is calculated, which is convenient for the operation and maintenance personnel to perform statistics and analysis on the telemetry response time adjusted by AVC, and helps the operation and maintenance personnel to detect the abnormal response time in time and analyze it in time possible problems, and then deal with the defects in a timely manner.
