Description

Technical Field

[0001] This invention relates to the field of dispatch automation system technology, and in particular to a method and apparatus for calculating telemetry response time. Background Technology

[0002] Currently, Automatic Voltage Control (AVC) has become a key function in dispatch automation systems. The main function of AVC is to use Supervisory Control and Data Acquisition (SCADA) systems to collect telemetry values ​​of reactive power from the main transformers and 10kV bus voltage at each substation. It then determines in real time whether these telemetry values ​​are exceeding limits and automatically controls the tap positions of the main transformers and capacitors / reactors at each substation to restore the reactive power and 10kV bus voltage values ​​to within acceptable ranges.

[0003] However, the AVC application in the dispatch automation system is extremely sensitive to the substation data collected by SCADA, especially the real-time values ​​of reactive power on the high-voltage side of the main transformer and the 10kV bus voltage. The accuracy of these two values ​​directly affects whether the AVC application generates a regulation strategy, and what regulation strategy it generates. If the values ​​are inaccurate or out of sync, it will directly lead to incorrect judgments by the AVC application, resulting in incorrect control strategies. This can cause the substation voltage or reactive power to exceed limits and not be adjusted in time, or even be over-adjusted. This not only affects the grid voltage operation qualification rate, but in severe cases, it can lead to grid voltage fluctuations, causing electrical appliances to burn out and malfunction.

[0004] However, in routine automated operation and maintenance analysis, when the data volume in the communication channels between some substations and the master station is large, the substation needs to send a large amount of telemetry data to the master station. When the AVC controls the equipment in the substation, the reactive power on the high-voltage side of the main transformer and the 10kV bus voltage cannot be updated in time. In this case, because the data is still in an out-of-limit state, the AVC will generate a new strategy for another adjustment, resulting in over-adjustment of the actual voltage or reactive power on site, affecting the actual voltage qualification rate.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0051] Figure 1This is a flowchart illustrating the steps of a telemetry response time calculation method according to an embodiment of the present invention.

[0052] Figure 2 This is a structural block diagram of an embodiment of a telemetry response time meter device according to the present invention. Detailed Implementation

[0053] This invention provides a method and apparatus for calculating telemetry response time, which is used to ensure the data synchronization of a scheduling automation system and guarantee the stability and security of AVC operation.

[0054] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0055] Please see Figure 1 , Figure 1 This is a flowchart illustrating the steps of a telemetry response time calculation method according to an embodiment of the present invention, which specifically includes the following steps:

[0056] Step S101: Obtain adjustment and control information for AVC applications;

[0057] In this embodiment of the invention, each gear adjustment and capacitor / reactor switch control operation of the AVC application is monitored to capture information on each adjustment control event. When it is determined that a control event has occurred in the control event information, that is, gear adjustment or capacitor / reactor switch control has occurred, the calculation program is started.

[0058] Step S102: When the adjustment control information is control, determine the control type;

[0059] Step S103: Obtain the rated parameters corresponding to the control type from the preset AVC database;

[0060] Specifically, the control types include: capacitor / reactor switch adjustment and gear adjustment; the rated parameters include: rated capacity of capacitor / reactor, bus adjustment sensitivity, and gear distance parameters; the rated parameters corresponding to the control type are obtained from a preset AVC database, including:

[0061] If the control type is capacitor / reactor switch regulation, then obtain the rated capacity of the target capacitor / reactor and the bus regulation sensitivity of the target bus section from the AVC database;

[0062] If the control type is gear adjustment, then the gear distance parameter of the target main transformer is obtained from the AVC database.

[0063] In this embodiment of the 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 system's preset AVC database; if the control type is gear adjustment, the gear distance parameter of the main transformer is obtained from the AVC database.

[0064] It should be noted that the bus regulation sensitivity is the AVC regulation parameter set in the AVC database, representing the change in the 10kV bus voltage caused by the connection or disconnection of a unit capacity capacitor / reactor. If a capacitor has a capacitance of 6MVar and a voltage regulation sensitivity of 0.03, then the connection or disconnection of this capacitor is expected to cause a change in the corresponding bus voltage of 6MVar * 0.03 = 0.18kV. That is, the expected voltage change caused by the connection or disconnection of this capacitor / reactor is calculated as the product of the voltage regulation sensitivity and the capacitor capacitance.

[0065] In addition, the span parameter can be understood as: the change in 10kV bus voltage caused by raising or lowering one span. If the span is 1.5%, it means that raising or lowering one span will cause a change in 10kV bus voltage of 10kV*0.015=0.15kV.

[0066] Meanwhile, adjusting the gear has almost no effect on the reactive power of the main transformer, so there is no need to remotely monitor the reactive power of the main transformer when adjusting the gear.

[0067] Step S104: Based on the topological connection relationship and the control type, obtain the location of the telemetry object to be monitored and its telemetry value.

[0068] Specifically, it includes:

[0069] Based on the topological connection relationship, locate the position of the telemetry object to be monitored;

[0070] If the control type is capacitor / reactor switch regulation, then obtain the 10kV bus voltage value of the bus connected to the target capacitor / reactor and the reactive power of the main transformer.

[0071] If the control type is gear adjustment, then obtain the 10kV bus voltage value of the bus connected to the target main transformer.

[0072] In this embodiment of the invention, after the calculation program is started, the AVC application generates a strategy and issues commands, which can locate the telemetry values ​​that need to be monitored in real time according to the topology connection relationship of the AVC application. If the adjustment object is a capacitor / reactor switch, the monitored telemetry values ​​are the 10kV bus voltage value connected to the capacitor / reactor and the reactive power of the main transformer connected to the corresponding bus; if the adjustment object is a tap, the monitored telemetry values ​​are the 10kV bus voltage value of the bus connected to the target main transformer.

[0073] Step S105: Based on the telemetry difference between the telemetry value before control and the telemetry value after control, and in conjunction with the preset sensitivity and the rated parameters, determine the change type of the telemetry object after control; the change type includes: minor change and significant change;

[0074] Specifically, the preset sensitivity includes: adjusting sensitivity and gear parameters; based on the telemetry difference between the telemetry value before control and the telemetry value after control, combined with the preset sensitivity and the rated parameters, determining the change type of the telemetry object after control, including:

[0075] If the control type is capacitor / reactor switching regulation, then determine whether the voltage difference of the 10kV bus voltage value of the bus connected to the target capacitor / reactor before and after control is greater than the product of the regulation sensitivity and the rated capacity of the capacitor / reactor; and determine whether the power difference of the reactive power of the main transformer before and after control is greater than a preset percentage of the rated capacity of the capacitor / reactor; if yes, then determine that the change type is a significant change; if no, then determine that the change type is a minor change.

[0076] If the control type is gear adjustment, then determine whether the voltage difference between the 10kV bus voltage value of the target main transformer connected to the bus before and after control is greater than the product of the gear parameter and 10kV; if yes, then determine that the change type is a significant change; if no, then determine that the change type is a minor change.

[0077] In this embodiment of the 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 capacitor / reactor switch is successfully remote controlled is obtained as the start time, which represents the time point when the gear has been raised or lowered or the switch has been opened / closed.

[0078] Then, during the monitoring of the telemetry object and its telemetry values, when the telemetry values ​​change, the voltage value of the 10kV bus connected to the target main transformer after the change and the voltage change time, as well as the reactive power of the main transformer after the change and the power change time, are recorded.

[0079] Subsequently, a significant change judgment mechanism is activated to determine whether the change type is significant. Specifically, if the control type is capacitor / reactor control, the voltage difference is calculated, and the relationship between the voltage change value and the adjustment sensitivity is compared. If the voltage difference is greater than 50% of the expected voltage change caused by the capacitor / reactor being engaged or disengaged, 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 being engaged or disengaged, it is judged as a minor change. Then, the power difference of the main transformer's reactive power before and after control is calculated, and the relationship between the power difference and the rated capacity of the capacitor / reactor is compared. If the power difference is greater than 50% of the rated capacity of the capacitor / reactor, it is judged as a significant change. If the power difference is less than or equal to 50% of the rated capacity of the capacitor / reactor, it is judged as a minor change.

[0080] If the regulation control is set to gear adjustment, the following judgment on significant voltage changes is made: Calculate the voltage difference of the 10kV bus voltage of the target main transformer before and after control, and compare the voltage difference with the product of the gear 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; if the voltage difference is less than or equal to the product of the gear parameter and 10kV, it is judged as a minor change.

[0081] Step S106: When the change type is the significant change, calculate the telemetry response time.

[0082] In this embodiment of the invention, under normal circumstances, the telemetry value is continuously monitored until a significant change occurs. The time difference between the start time and the voltage change time is used as the telemetry response time for gear adjustment. The time difference between the start time and the voltage change time is used as the response time of the control voltage in capacitor / reactor switching adjustment. The time difference between the start time and the power change time is used as the response time of the main transformer to increase reactive power.

[0083] In an optional embodiment, when the change type is the significant change, after calculating the telemetry response time, the method further includes:

[0084] The telemetry response time is stored in the AVC database, and the average telemetry response time is calculated by combining the historical telemetry response times in the AVC database.

[0085] In this embodiment of the invention, the voltage or reactive power telemetry response time for each AVC application is stored in a database. The average telemetry response time for AVC regulation in the same substation is calculated using lists and related statistical methods. This facilitates the analysis and monitoring of the AVC regulation response characteristics of the substation by dispatchers and automation maintenance personnel. Any abnormal response time is addressed promptly.

[0086] It should be noted that the method of the present invention mainly utilizes the correspondence between devices and corresponding monitoring objects in the AVC (Automatic Dispatch Control) system to form a correspondence between AVC adjustment devices and corresponding monitoring telemetry points.

[0087] In this embodiment of the invention, after the AVC generation strategy adjusts and controls the device, the calculation process is initiated, and the time corresponding to the successful remote control is recorded as the starting point. Then, the AVC monitoring telemetry value of the target device is monitored in real time. When the telemetry value changes significantly, the telemetry refresh time is recorded as the recording end point. The telemetry response time is determined by calculating the time difference between the starting point and the recording end point. This embodiment of the invention obtains adjustment and control information of the AVC application; when the adjustment and control information is control, the control type is determined; the rated parameters corresponding to the control type are obtained from the preset AVC database; according to the topology connection relationship and the control type, the location of the telemetry object to be monitored and its telemetry value are obtained; based on the telemetry difference between the telemetry value before and after the control, combined with the preset sensitivity and the rated parameters, the change type of the telemetry object after control is determined; the change type includes: small change and significant change; when the change type is the significant change, the telemetry response time is calculated. When the change type of the telemetry object is determined to be a significant change, the corresponding telemetry response time is calculated. This allows maintenance personnel to statistically analyze the telemetry response time of AVC adjustments, helping them to promptly identify abnormal response times and analyze potential problems, thereby enabling timely defect handling.
