Description

Technical Field

[0001] The present application relates to the field of electric power technology, and in particular to a statistical method for calculating the number of remote control channel switching times and a related device. Background Art

[0002] At present, in the power dispatching automation system, there are two channels between each substation and the main station, namely the network channel and the analog channel, which are the main and backup channels for each other, responsible for the communication between the substation and the main station, realizing the transmission of the four remote signals between the substation and the main station, and ensuring the safe and stable operation of the power grid. At the same time, only one of the two channels is the main channel, and the other is the backup channel. When the main channel fails or is abnormal, the system will automatically switch the backup channel to the main channel.

[0003] However, the power grid automation system is currently highly dependent on the channel between the substation and the main station. When the channel is switched frequently, it means that the reliability of the channel is not high. In addition, when the channel is switched, it may cause the leakage of the four remote signals. In serious cases, it may even affect the normal operation of the power system and reduce the power supply reliability.

[0004] At present, the dispatching automation system has not yet implemented monitoring of the number of channel switching times, and is unable to quickly and timely obtain the operating status of each channel. Only when a fault occurs or the four remote control signals are missed, the number of channel switching times will be manually counted through offline messages to find the problem, and channel fault warning cannot be achieved. Summary of the invention

[0005] The present application provides a statistical method for the number of remote control channel switching and a related device, which are used to solve the technical problem that the prior art cannot monitor the number of remote control channel switching and cannot obtain the operating status of each channel in a timely manner.

[0017] A second aspect of the present application provides a system for counting the number of telecontrol channel switching times, the system comprising:

[0018] The storage module is used to store the general call message sent from the master station to the substation;

[0019] An acquisition module, used to acquire the message documents of the first channel and the second channel stored in the substation server;

[0032] Compared with the prior art, the present application mainly analyzes and matches the channel messages of each substation on a daily basis. The messages of all channels are stored in the server on a regular basis every day, and these channel messages are read and analyzed by accessing the server. After each channel switch, the channel message will be called up by the master station. The substation sends the total call number, and the master station will send the total call message to the substation. After the substation receives the total call message, it will send the total call data. The message frames of these total call messages are fixed. As long as these fixed message frames are found, the number of channel switching times can be obtained. The statistical method of the present application is used to monitor the number of substation channel switching times every day, so that it is possible to timely determine which substation channels may have abnormal conditions, and to troubleshoot and rectify the channels. It avoids the leakage of four remote signals due to the failure to timely discover the abnormality of the substation channel, causing the dispatcher to be unable to normally monitor the status of each device in the substation, and the occurrence of power grid safety accidents. Thereby solving the technical problem that the prior art cannot monitor the number of remote channel switching times and cannot obtain the operating status of each channel in time.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] See also Figure 1 , a statistical method for the number of telecontrol channel switching provided in an embodiment of the present application includes:

[0038] Step 101, save the general call message sent by the master station to the substation;

[0039] It should be noted that all the channel messages of the substation will be stored in the server regularly every day, and these channel messages will be read and analyzed by accessing the server. After each channel switch, the channel message will be called up, and the master station will send a general call message to the substation.

[0040] Step 102: Obtain the message documents of the first channel and the second channel stored in the substation server;

[0041] It should be noted that this embodiment reads the message documents of the two channels of the substation received the previous day from the power dispatching automation system history server on a regular basis every day. Those skilled in the art can also obtain message documents according to actual needs, such as obtaining them once a week, etc., which will not be repeated here.

[0042] Step 103, matching the message document with the general call message, obtaining a first value of successful matching of the first channel and a second value of successful matching of the second channel;

[0043] Specifically, each frame message in the message document of the first channel is matched with the general call message, and the first value of successful matching is calculated; each frame message in the message document of the second channel is matched with the general call message, and the second value of successful matching is calculated.

[0044] It can be understood that the message of one channel is read frame by frame and matched with the general call message. If the match is unsuccessful, the next frame of the message is read. If the match is successful, the count is increased by one until all the messages of the previous day are read. Then the message of another channel is read frame by frame and matched with the general call message. If the match is unsuccessful, the next frame of the message is read. If the match is successful, the count is increased by one until all the messages of the previous day are read.

[0045] Step 104: The sum of the first value and the second value is used as the switching times of the remote control channel.

[0046] Add the counts of the two channels of this substation to get the number of times this substation switched channels the previous day, and record it in the report. After analyzing one substation, continue to read the channel message of the next substation according to the above steps until all substations are analyzed.

[0047] This embodiment mainly analyzes and matches the channel messages of each substation on a daily basis. The messages of all channels are stored in the server on a regular basis every day, and these channel messages are read and analyzed by accessing the server. After each channel switch, the channel message will be called up. The master station will call up the channel message. The substation sends the total call number. The master station will send the total call message to the substation, and the substation will send the total call data after receiving the total call message. The message frames of these total call messages are fixed. As long as these fixed message frames are found, the number of channel switching times can be obtained. The statistical method of the present application is used to monitor the number of substation channel switching times every day, so that it is possible to timely determine which substation channels may have abnormal conditions, and to troubleshoot and rectify the channels. It avoids the leakage of four remote signals due to the failure to timely discover the abnormality of the substation channel, causing the dispatcher to be unable to normally monitor the status of each device in the substation, and the occurrence of power grid safety accidents. Thereby solving the technical problem that the prior art cannot monitor the number of remote channel switching times and cannot obtain the operating status of each channel in time.

[0048] The above is Example 1 of a statistical method for the number of remote control channel switching times provided in the embodiments of the present application, and the following is Example 2 of a statistical method for the number of remote control channel switching times provided in the embodiments of the present application.

[0049] See also Figure 2 , a statistical method for the number of telecontrol channel switching provided in an embodiment of the present application includes:

[0050] Step 201, save the general call message sent by the master station to the substation;

[0051] Step 202: Obtain the message documents of the first channel and the second channel stored in the substation server;

[0052] Step 203: Match the message document with the general call message to obtain a first value of successful matching of the first channel and a second value of successful matching of the second channel;

[0053] Step 204: The sum of the first value and the second value is used as the switching times of the telecontrol channel.

[0055] Step 205: When the switching times of the telecontrol channel is greater than the preset switching times threshold, an alarm signal is sent to the staff;

[0056] It should be noted that, in the case where the number of telecontrol channel switching is abnormal, this embodiment sends an alarm signal to the staff so that the staff can understand the channel operation status between substations in a timely manner.

[0057] Step 206: sort the switching times calculated periodically each time in order of the switching times to generate a remote control channel switching times report.

[0058] It should be noted that the number of times the substation channels are switched on that day is calculated and recorded in a report, and the channels are sorted by the number of times they are switched. Through the report, it is possible to visually observe which channels are abnormal.
