Embodiment 1

[0053] For ease of understanding, see figure 1 , an embodiment of a substation jump data monitoring method provided by the present application, including:

[0054] Step 101, the first telecontrol device collects telemetry values ​​of monitored telemetry points.

[0055] Step 102, the first remote control device compares the telemetry value with the jump threshold, and if the telemetry value exceeds the jump threshold, sends request jump status information to the second remote control device that collects the telemetry value at the same time as the first remote control device.

[0056] Step 103, the first remote device receives the jump status signal returned by the second remote device according to the request jump status information, the jump status signal is in the jump state or not in the jump state.

[0057] Step 104, the first telecontrol device sends telemetry of the belt quality to the master station according to the jump state signal, and sends an alarm signal to the ...

Embodiment 2

[0062] For ease of understanding, see figure 2 and image 3 , the present application provides another embodiment of a substation jump data monitoring method, including:

[0063] Step 201, the first remote device continuously collects three telemetry values ​​of the monitored telemetry points.

[0064] Step 202, the first telecontrol device calculates the first absolute value of the difference between the second telemetry value and the first telemetry value, compares the first difference absolute value with the jump threshold, if the first difference absolute value exceeds the jump threshold If the threshold is changed, the telemetry jump judgment time is started.

[0065] Step 203, the first telecontrol device calculates the second absolute value of the difference between the third telemetry value and the second telemetry value, and if the second absolute value of the difference exceeds the jump threshold, it is judged whether the direction of the two jumps is opposite , ...

example

[0075] figure 2 , the absolute value of the difference between the telemetry value h and telemetry g is greater than the jump threshold, the first telecontrol device starts the jump determination time t when receiving the telemetry value h, and the absolute value of the difference between the telemetry values ​​i and h is greater than the jump threshold threshold, but it is consistent with the jump direction of telemetry h and telemetry g, then the telemetry value h is not jump data and will be transmitted to the master station with the original quality. This example corresponds to the process of normal power flow variation.

[0076] figure 2 , the absolute value of the difference between the telemetry values ​​i and h is greater than the jump threshold, the first telecontrol device starts the jump determination time t when receiving the telemetry value h, and the absolute value of the difference between the telemetry values ​​j and i is greater than the jump threshold , a...

Abstract

The invention discloses a transformer substation jump data monitoring method, device and system, and the method comprises the steps: comparing a telemetering value of a monitored telemetering measurement point with a jump threshold when telecontrol equipment collects the monitored telemetering measurement point, judging whether the telemetering jumps or not, and when the telecontrol equipment monitors the jump of the telemetering measurement point, sending request jump state information to opposite telecontrol equipment connected with the same master station, obtaining the jump state of the opposite telecontrol equipment, if the opposite telecontrol equipment does not monitor telemetering jump, remotely transmitting telemetering with quality to the master station and sending a telecontrolalarm signal to the master station, and if the opposite telecontrol equipment also monitors the telemetering jump, remotely performing telemetering with quality with the main station, and sending a spacer layer jump alarm signal to the main station, so the technical problems that abnormal data cannot be identified at a data source end and data quality management caused by telemetering jump is notfacilitated in an existing transformer substation telemetering jump data identification method are solved.

Description

technical field [0001] The present application relates to the technical field of power system automation, in particular to a method, device and system for monitoring substation jump data. Background technique [0002] With the deepening of the smart grid construction, each substation will deploy two telecontrol devices as backup to undertake the communication function with the main station. The telemetry data collected by the smart devices in the substation increases rapidly, and the telecontrol The telemetry jump data is sent to the master station far away, resulting in a decrease in the data quality of the master station. At present, the identification of telemetry jump data adopts the method of master station judgment. Although the master station can identify the jump data, it cannot identify the abnormal data at the data source end, which increases the load of the master station system and communication channel. It is beneficial to data quality governance caused by tele...
