The failure of the stabilization control device to operate may cause the stability of the power grid to be damaged, and even cause a large-scale power outage.

The switch transmission of the stabilization control device is an important measure to prevent the failure of the stabilization control device to operate.

Since the standard configuration has 16 load shedding outlets, the export transmission requires load interval power outages and it is impossible to cut off power in multiple intervals at the same time, which leads to a long verification period for all exports and low efficiency. Power outages of equipment during export transmission will also pose certain risks to the power grid. In addition, the transmission analysis method of the current export transmission verification method is not intelligent enough, which not only leads to a large workload for on-site operation and maintenance personnel to cut off power supply, but also prone to analysis errors.

[0052] The embodiments of the present invention provide a method, device, electronic device and storage medium for non-stop transmission of a stabilization control device, which are used to solve or partially solve the technical problems of long export transmission verification period, low efficiency, insufficient intelligence of transmission analysis means and easy analysis errors.

[0053] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] As an example, the existing stabilization and control device is not equipped with the function and circuit to start closing after the load is cut off. Since the standard configuration has 16 load-cutting outlets, the export transmission requires load interval power outages and it is impossible to cut off power in multiple intervals at one time, which leads to a long verification period for all exports and low efficiency. Power outages of equipment during export transmission will also pose certain risks to the power grid. Moreover, the transmission analysis means of the current export transmission verification method is not intelligent enough, which not only leads to a large workload for on-site operation and maintenance personnel to cut off power supply, but also prone to analysis errors. At present, there is no relevant technical solution for non-power-off transmission of stabilization and control devices.

[0055] Therefore, one of the core invention points of the embodiment of the present invention is: in view of the shortcomings of the current technology, a non-stop power transmission system and method of a stabilizing control device based on network message timing analysis is provided. The non-stop power transmission system of the stabilizing control device can mainly include a monitoring background with a built-in stabilizing control non-stop power transmission test module, a protection device and a measurement and control device respectively connected to the monitoring background through the station control layer network, and the measurement and control device is connected to the circuit breaker operation box through the stabilizing control device. Among them, the load shedding action timing message of the transmission test of the stabilizing control device is analyzed by the stabilizing control non-stop power transmission test module of the monitoring background, and after it is determined that the transmission test load shedding is correctly exported, the monitoring background automatically executes remote control closing. Therefore, without changing the existing functional architecture and external circuit of the stabilizing control device, the transmission test process of the stabilizing control device can be intelligently analyzed, all action timing messages and transmission result judgment analysis can be automatically summarized, and the non-stop power transmission of the stabilizing control device can be realized, which greatly improves the efficiency of the transmission export test of the stabilizing control device, reduces analysis errors, and avoids the grid risks caused by load interval power outages.

The circuit breaker operation box 106 is connected to the circuit breaker mechanism 107. At the same time, the circuit breaker mechanism 107 is also interconnected with the interval measurement and control device 104.

It is mainly used for the collection of analog and switch signal of substation end equipment and the remote control execution of primary equipment. Furthermore, the interval measurement and control device 104 refers to the measurement and control device belonging to the primary equipment corresponding to the substation.

[0065] The circuit breaker mechanism 107 refers to a mechanical mechanism used to realize the opening and closing of the circuit breaker and reflect the status of the circuit breaker.

[0066] In an embodiment of the present invention, a non-stop power transmission system of a stabilizing control device based on network message timing analysis is provided. The non-stop power transmission system of the stabilizing control device can mainly include a monitoring background with a built-in stabilizing control non-stop power transmission test module, a protection device and a measurement and control device respectively connected to the monitoring background through a station control layer network, and the measurement and control device is connected to the circuit breaker operation box through the stabilizing control device. Among them, the load shedding action timing message of the transmission test of the stabilizing control device is analyzed by the stabilizing control non-stop power transmission test module of the monitoring background, and after it is determined that the transmission test load shedding has a correct exit action, the monitoring background automatically executes remote control closing. Therefore, without changing the existing functional architecture and external circuit of the stabilizing control device, the transmission test process of the stabilizing control device can be intelligently analyzed, all action timing messages and transmission result judgment analysis can be automatically summarized, and non-stop power transmission of the stabilizing control device is realized, which greatly improves the efficiency of the transmission exit test of the stabilizing control device, reduces analysis errors, and avoids the grid risks caused by load interval power outages.

[0067] Based on the above-mentioned embodiment, the non-stop power transmission system of the stabilizing control device is described. Figure 2 , shows a flowchart of a method for non-stop transmission of a stabilizing control device provided by an embodiment of the present invention, which may specifically include the following steps:

[0068] Step 201, control to start the stabilization control non-stop transmission test monitoring, based on the preset state judgment condition, determine whether the test state of the stabilization control device is normal;

[0069] First, monitor the start of the stable control non-stop power transmission test in the background, and confirm whether the stable control non-stop power transmission test module starts normally. If successful, continue to the next step, otherwise end.

[0070] Next, determine whether the test status of the stabilizing control device is normal. If the test status of the stabilizing control device is normal, continue; otherwise, end.

[0071] Among them, the test status judgment conditions of the stabilization and control device mainly include the following points:

[0072] 1. The test plate of the stabilizing device is put into operation;

[0073] 2. There is no alarm information from the stabilization control device;

[0074] 3. The interval measurement and control device and the protection device communicate normally with the monitoring background;

[0075] 4. The disconnection signal status of the circuit breaker control circuit of the load shedding interval of the stabilizing control device is reset.

[0076] When the above conditions are met, the test state of the stabilization control device is in normal state. The above state information is transmitted to the monitoring background by the common measurement and control device, interval measurement and control device and protection device.

[0077] In a specific implementation, based on the preset status judgment conditions, it is determined whether the test status of the stabilization and control device is normal. It can be as follows: determine whether the stabilization and control device simultaneously satisfies the conditions that the test pressure plate is put into operation, there is no alarm information, the communication is normal, and the disconnection signal status of the circuit breaker control circuit during the load shedding interval is reset; if all of the conditions are met at the same time, the test status of the stabilization and control device is in a normal state; if all of the conditions cannot be met at the same time, the test status of the stabilization and control device is in an abnormal state.

[0078] Step 202, if the test state of the stabilization control device is normal, verify the correctness of the transmission setting value of the stabilization control device, and based on the verification result, determine whether the stabilization control output is consistent with the setting value;

[0079] This step mainly implements the transmission test of the stabilization control device. Specifically, the tester can exit the load interval outlet pressure plate of the stabilization control device according to the strategy setting of the stabilization control device, and verify the correctness of the strategy setting outlet of the stabilization control device by adding analog quantities such as current and voltage externally. When the outlet is consistent with the setting, proceed to the next step, otherwise the test ends after recording the logic abnormality of the stabilization control device.

[0080] Among them, the strategy setting value of the stabilization control device is the action value of the stabilization control device set by the setting setting personnel according to the power grid system flow conditions, and the load interval combination corresponding to the action value of the stabilization control device.

[0081] In the specific implementation, the correctness of the transmission setting of the stabilization control device is verified, and based on the verification result, it is judged whether the stabilization control output is consistent with the setting, which can be:

[0082] Obtain the strategy setting value of the stabilization control device;

[0083] According to the strategy setting of the stabilizing control device, exit the load interval outlet pressure plate of the stabilizing control device, and verify the correctness of the strategy setting outlet of the stabilizing control device by adding external current and voltage analog quantities;

[0084] When the constant value export of the stabilization control device strategy is verified correctly, the stabilization control export is consistent with the constant value setting;

[0085] When the constant value export verification of the stabilization control device strategy is wrong, the stabilization control export is inconsistent with the constant value setting.

[0086] Step 203, when the stabilization control export is consistent with the fixed value setting, determine whether the stabilization control device is in export action, and when the stabilization control device is in export action, record the export action timing message of the stabilization control device;

[0087] The stable control non-stop power transmission test module monitors whether the stable control device is in outlet action. Specifically, firstly, the load interval outlet pressure plate of the stable control device is put into operation, and the external current and voltage are input again. Then, the stable control non-stop power transmission test module is used to monitor whether the stable control device is in correct outlet action (i.e., whether the load interval circuit breaker is cut correctly). If the outlet action is correct, the next step is executed, otherwise the abnormal outlet situation is recorded.

[0088] Among them, the action exit judgment conditions can mainly include the following points:

[0089] a. The stabilization control device sends an action signal;

[0090] b. The load interval circuit breaker position changes from closed position to open position, at which time the load interval current value will eventually be less than 0.05In (In represents the interval rated current value);

[0091] c. No protection device sends an action message during the load interval circuit breaker position change; this condition is set to ensure that the circuit breaker change is not caused by the protection device cutting off the power grid system fault.

[0092] When all the above judgment conditions are met, it is judged that the transmission outlet test of the stabilizing control device has correct outlet action.

[0093] In a specific implementation, to determine whether the stabilizing control device is in export action, the following can be done: re-engage the load interval export pressure plate of the stabilizing control device, and add the external current and voltage analog quantity again; and determine whether the stabilizing control device is in export action in combination with the export judgment conditions of the action.

[0094] More specifically, in combination with the action exit judgment conditions, whether the stabilization control device exits the action can be judged as follows: whether the stabilization control device sends an action signal, the load interval circuit breaker position changes from closed position to open position, and no protection device sends an action message during the load interval circuit breaker position change; if so, the stabilization control device exits the action correctly; if not, the stabilization control device cannot exit the action correctly.

[0095] During the non-stop power transmission process, the stabilization control non-stop power transmission test module records the output action sequence message of the stabilization control device. Among them, the output action sequence message refers to the sequence message table formed when the position of the load interval circuit breaker changes after the stabilization control device sends an action message.

[0096] Step 204, when the load bay circuit breaker is in the open state, automatically and remotely close the load bay circuit breaker;

[0097] After the stable control non-stop transmission test module determines the load interval circuit breaker position, it automatically sends a remote control closing command to the interval measurement and control device after a delay of 500ms (time unit: milliseconds). The interval measurement and control device sends a closing pulse to the circuit breaker operation box, and the circuit breaker closes, thereby achieving the purpose of automatically remotely closing the load interval circuit breaker and realizing non-stop transmission.

[0098] It should be pointed out that the delay of 500ms before issuing the remote control closing command is to avoid the circuit breaker opening and closing time interval being too short, which may cause damage to the equipment. Through experiments, the present invention recommends setting the delay time to 500ms. Those skilled in the art can set the closing delay time to other values ​​according to actual needs. However, the set delay time shall not be greater than the reclosing time of the interval protection device, which is generally 1s (time unit: second). It is understandable that the present invention is not limited to this.

[0099] In a specific implementation, when the load interval circuit breaker is in the open state, the automatic remote control closing of the load interval circuit breaker can be: determining whether the load interval circuit breaker is currently in the open state; if so, automatically generating a remote control closing command after a preset delay time, and the remote control closing command is used to automatically remotely close the load interval circuit breaker to achieve non-stop transmission.

[0100] Step 205, obtaining the built-in action message of the stabilization and control device, when the built-in action message is inconsistent with the export action timing message, recording the abnormality and closing the stabilization and control non-stop transmission test monitoring.

[0101] The built-in action message of the stabilization control device refers to the action message pre-written by the test personnel. Its content includes different action records and specific load shedding related actions at different time nodes.

[0102] The export action sequence message is used to compare with the action message in the stabilization control device. For example, the comparison between the built-in action message of the stabilization control device and the export action sequence message is shown as follows: Figure 3 shown.

[0103] The message comparison is to confirm whether the actual output is consistent with the device display. In actual situations, it may happen that the stabilization device cut-off instruction is load 01, but the actual output load 02 circuit breaker. In this case, the monitoring background receives the circuit breaker position change message, corresponding to the load 02 circuit breaker position change.

[0104] In the actual transmission process, the stabilization control device can only send an action signal to the monitoring background, but cannot transmit the specific load removal interval information to the monitoring background. Therefore, the background needs to record the timing message of the actual action to remove the load interval, and compare the timing message with the action message in the stabilization control device to confirm whether the load removal action sequence is consistent. Among them, the comparison content is specifically the time of the load interval removal instruction of the stabilization control device and the time when the corresponding load interval circuit breaker of the monitoring background changes from open to closed. The time is specific to milliseconds. For example: 2025-01-07 10:17:56.454. Since there is a fixed delay in the action of the relay, and there is a mechanical action delay when the circuit breaker changes from the closed position to the open position, it is normal for the circuit breaker opening time to be delayed within 100ms than the load shedding action time. When the message comparison is inconsistent, record the abnormal situation of the actual action timing. When the message comparison is consistent, proceed to the next action.

[0105] Combined with the above introduction, in some embodiments, when the built-in action message is inconsistent with the export action timing message, the abnormality is recorded and the stable control non-stop power transmission test monitoring is closed, which can be specifically:

[0106] Determine whether the egress action timing message is consistent with the built-in action message;

[0107] If yes, then collect the records, generate a report file, and close the stable control non-stop transmission test monitoring;

[0108] If not, after recording the actual action sequence abnormal information of the stabilization and control device, summarize the records, generate a report file, and close the stabilization and control non-stop transmission test monitoring.

[0109] During the non-stop power transmission process, the stable control non-stop power transmission test module can summarize the non-stop power transmission work records in real time, generate a report file and archive it to the fixed path of the monitoring background, and finally close the stable control non-stop power transmission test monitoring. Or when the non-stop power transmission is completed, the stable control non-stop power transmission test module uniformly summarizes the non-stop power transmission work records, generates a report file and archives it to the fixed path of the monitoring background, and finally closes the stable control non-stop power transmission test monitoring to end the entire process.

[0110] In an embodiment of the present invention, in combination with the non-stop power transmission system of the stabilizing control device introduced in the aforementioned embodiment, a non-stop power transmission method of the stabilizing control device based on network message timing analysis is provided. The load shedding action timing message of the transmission test of the stabilizing control device is analyzed by the stabilizing control non-stop power transmission test module of the monitoring background. After determining that the load shedding of the transmission test is a correct export action, the monitoring background automatically executes remote control closing. Therefore, without changing the existing functional architecture and external circuit of the stabilizing control device, the transmission test process of the stabilizing control device can be intelligently analyzed, all action timing messages and transmission result judgment analysis can be automatically summarized, and non-stop power transmission of the stabilizing control device is realized, which greatly improves the efficiency of the transmission export test of the stabilizing control device, reduces analysis errors, and avoids the grid risks caused by load interval power outages.

[0111] For better explanation, refer to Figure 4 , showing a schematic diagram of the overall process of a non-stop power transmission method of a stabilizing control device provided by an embodiment of the present invention. It should be pointed out that this embodiment only briefly describes the general process of non-stop power transmission of the stabilizing control device, and the specific implementation process of each step can be understood by referring to the relevant content in the aforementioned embodiment, which will not be described here. It can be understood that the present invention does not limit this.

[0112] Step 401, monitoring background stable control non-stop transmission test monitoring starts; continue to execute step 402.

[0113] Step 402 , determine whether the stable control non-stop power transmission test module is successfully started; if so, jump to step 403 ; if not, jump to step 408 .

[0114] Step 403 , based on the preset state judgment condition, determine whether the test state of the stabilization control device is normal; if so, jump to step 404 ; if not, jump to step 408 .

[0115] Step 404, execute the transmission setting correctness test of the stabilization control device, that is, based on the strategy setting of the stabilization control device, verify the correctness of the transmission setting of the stabilization control device; based on the verification result, determine whether the stabilization control output is consistent with the setting logic (setting); if so, jump to step 405; if not, after recording the abnormal situation of the logic of the stabilization control device, summarizing the records to generate a report file for archiving, jump to step 408.

[0116] Step 405, execute the transmission outlet test of the stabilizing control device; based on the action outlet judgment condition, determine whether the stabilizing control device has exited the action; if so, jump to step 406; if not, after recording the abnormal situation of the stabilizing control device outlet, summarizing the records to generate a report file for archiving, jump to step 408.
