Embodiment 1

[0044] This embodiment discloses a processing method for judging whether the substation RTU telemetry data is refreshed, such as figure 1 and figure 2 , including the following steps:

[0045] S1: The master station reads the database and obtains relevant data of the substation;

[0046] S2: The master station counts the remote measurements refreshed in the data sent by the substation;

[0047] S3: Calculate the judgment basis of the refresh data, compare it with the preset refresh data threshold, and start the alarm and defect elimination process according to the judgment result.

[0048] Obtaining relevant data of the substation in step S1 includes obtaining the total number M of telemetry points of the substation.

[0049] In step S2, count the telemetry refreshed in the data sent by the substation, specifically:

[0050] Every time a telemetry is refreshed, the count is added by 1, and finally the total number of refreshed telemetry m is obtained.

[0051] The judgme...

Embodiment 2

[0062] This embodiment provides a system for judging whether the RTU telemetry data of a substation is refreshed, such as image 3 ,include:

[0063] A data acquisition module, the data acquisition module reads the database to obtain substation related data;

[0064] A counting module, the counting module counts the remote measurements refreshed in the data sent by the substation;

[0065] Judgment processing module, the judgment processing module calculates the refresh data judgment basis, compares it with the preset refresh data threshold, and starts the alarm and defect elimination process according to the judgment result.

[0066] The substation-related data acquired by the data acquisition module includes the total number M of substation telemetry points.

[0067] The judgment processing module starts the alarm and defect elimination process according to the judgment result, specifically:

[0068] If the refresh data judgment basis is less than the refresh data threshold...

Abstract

The invention discloses a method for judging whether substation RTU telemetry data is refreshed or not. The method comprises the following steps: S1, a master station reads a database and acquires substation related data; S2, the main station counts the refreshed remote measurement quantity in uploaded data of a transformer substation; and S3, a refreshing data judgment basis is calculated, the refreshing data judgment basis is compared with a preset refreshing data threshold, and an alarm and defect elimination process is started according to a judgment result. By automatically and intelligently analyzing the number of the telemetering points of the transformer substation and the uploaded telemetering data, the defect discovery rate of data refreshing stopping is increased, the defect elimination time is greatly shortened, meanwhile, through alarming and defect elimination processes, the data uploading stability is guaranteed, and the error correction capacity of a dispatching monitoring system is improved.

Description

technical field [0001] The invention relates to the field of substation maintenance, and more specifically, to a method and system for judging whether RTU telemetry data of a substation is refreshed or not. Background technique [0002] With the continuous improvement of substation intelligence, the network communication message between substation RTU and automation master station has become the main way of information exchange. In order to perceive the health status of substation equipment in real time, it is necessary to record and analyze the messages, filter out the abnormal data and notify the operation and maintenance personnel to deal with the defects in time. If the message telemetry data stops refreshing, it will cause data statistics errors, inaccurate power measurement calculations, and even cause AVC and protection malfunctions, which will affect the normal operation of the power grid at least, and cause major safety accidents at worst. Real-time analysis can be...
