Description

Overhauling determination method and device for telecontrol device
Technical Field
The invention relates to a transformer substation safety technology field, in particular to a maintenance determining method and device for a telecontrol device.
Background
After data such as remote signaling and remote measuring of the transformer substation are collected by the telecontrol device, the data are transmitted to the power dispatching automation system through a telecontrol message data link. Based on the data, a power system dispatcher monitors the whole network in real time, and meanwhile, a voltage reactive power control system (AVC system) can also regulate a transformer substation of the whole network by referring to telemetering data, so that the power grid is ensured to operate at a safe and stable level.
Currently, the communication protocols 101 and 104 are widely used to standardize the communication between the telecontrol device and the power dispatching automation system. Both communication protocols specify the priority of the data to be uploaded, i.e. more important data, such as link initialization messages, general recall messages, etc., are uploaded first, while less important data, such as telemetry changes, are uploaded later. Therefore, when tripping occurs, the remote control device at the substation end simultaneously sends a large number of remote signaling and remote measuring messages, the data request message and the remote control message at the master station end cannot be responded in time, and even the master station end message is not responded, and the remote control device can be considered to have a defect problem at the moment. When the telecontrol device does not respond to the master station message, the remote control response overtime and the key remote measurement change cannot be timely sent, and the power system dispatcher cannot carry out switch remote control, so that the normal operation of dispatching core services is directly influenced.
For the above problems, the conventional solution is to take corresponding measures, such as manual calling or notification of a substation operator to check the remote motivation, when an automatic maintainer or a power system dispatcher finds that the remote device of a certain substation does not return a message from an alarm window or an event window. Obviously, the traditional method is comparatively lagged and inefficient, and consumes a great deal of manpower and maintenance cost.

Detailed Description
The embodiment of the invention provides a method and a device for determining overhaul of a telecontrol device, which are used for monitoring the running state of a telecontrol machine of a transformer substation in real time, checking the telecontrol device with possible problems and solving the problems of message missing and/or message non-response of the telecontrol device when a power grid trips.

Although the widely used communication protocols 101 and 104 at the present stage are normal, the remote signaling deflection, SOE and remote control response message uploading of the substation end cannot be lost, in practical application, when the substation end trips, the remote control device at the substation end simultaneously sends a large number of remote signaling and remote measurement messages, and the remote control device cannot respond to the data request message and the remote control message of the master station end in time, even does not respond to the message of the master station end, and such remote control device can be considered to have a defect problem. When the telecontrol device does not respond to the master station message, the remote control response overtime and the key remote measurement change cannot be timely sent, the power system dispatcher cannot perform switch remote control, and the normal operation of dispatching core services is directly influenced, for example: the real-time load condition of a station end cannot be known in time from an SCADA system, so that telemetering of 10kV bus voltage and the like can be involved, the reference telemetering of AVC cannot be refreshed in time, and blind adjustment to a certain degree easily exists.
In the present stage, to solve the problem, the adopted method is relatively lagged and low in efficiency, and a large amount of manpower and maintenance cost are consumed, so that the invention provides a method for determining the overhaul of the telemechanical device, which comprises the following steps:

In a specific implementation, when a user inputs a detection instruction of the telemechanical device, the first frame of message data is determined, and the flag bit is used as key information to determine the next frame of message data after the first frame of message data.
Of course, in practical applications, there may be a case where there is no next frame of message data after the first frame of message data, and at this time, the current first frame of message data is removed, and the first frame of message data is re-determined.
S2, adjusting the total request message quantity and/or the unanswered request message quantity according to the flag bit of the next frame message data and the flag bit of the first frame message data;
s3, judging whether new message data exists after the next frame of message data; if yes, go to step S4; if not, go to step S5;
s4, adjusting the total request message quantity and/or the unanswered request message quantity according to the flag bit of the next frame message data and the flag bit of the new message data; returning to step S3;
and S5, determining whether the target telecontrol device needs to perform defect analysis according to the number of the unanswered request messages and the total number of the request messages.
In the embodiment of the present invention, by S1, in response to the received first frame of message data, the next frame of message data corresponding to the first frame of message data is determined; s2, adjusting the total request message quantity and/or the unanswered request message quantity according to the flag bit of the next frame message data and the flag bit of the first frame message data; s3, judging whether new message data exists after the next frame of message data; if yes, go to step S4; if not, go to step S5; s4, adjusting the total request message quantity and/or the unanswered request message quantity according to the flag bit of the next frame message data and the flag bit of the new message data; returning to step S3; and S5, determining whether the target telecontrol device needs to perform defect analysis according to the number of the unanswered request messages and the total number of the request messages. The method comprises the steps of counting the total number of request messages received by a substation from a master station, the number of request messages which are not responded and the corresponding proportion, and comprehensively evaluating whether the telecontrol device has the necessity of maintenance.

and step S207, determining that the target telecontrol device does not have the necessity of maintenance.
In the embodiment of the invention, the number of the request messages which are not responded is divided by the total number of the request messages of the station in one day, the proportion of the number of the request messages which are not responded to in the total number of the message requests in one day is obtained and stored in the database, and when the proportion of the number of the request messages which are not responded to in the total number of the message requests in one day exceeds 5%, the telecontrol device is considered to have defects and needs to be tested and overhauled immediately.
Meanwhile, after the analysis of the one frame of request message is completed, the next frame of request message is continuously read and analyzed until all the request messages of the transformer substation on the day are analyzed.
