Description

Technical Field

[0001] This invention relates to the field of automatic transfer switch (ATS) technology, and more specifically, to a remote testing method and system for the transmission of a 110kV ATS device. Background Technology

[0002] In multi-stage series-supply 110kV power systems, to improve power supply reliability, remote automatic transfer switch (ATS) systems are widely used to automatically connect a backup power source at the system open-loop point in the event of a 110kV busbar failure at a substation, quickly restoring power supply to the busbar of the substation that has lost voltage. The working principle of the ATS system is as follows: when a main power supply failure is detected and a series of logical conditions are met, the system will automatically trip the switch of the under-voltage line and close the backup switch at the open-loop point within a predetermined time, completing the automatic power switching and promptly restoring power supply to the busbar of the substation that has lost voltage.

[0003] Verifying the effectiveness of the 110kV automatic transfer switch (ATS) and ensuring its accurate operation in actual operation is a necessary step before the ATS is put into operation in a power system. In related technologies, the transmission verification of the 110kV ATS involves conducting a full-scale transmission test at the substation. This process includes adjusting the system to a specific operating state, putting the ATS in a charging state, and then manually disconnecting the main power supply line switch to simulate a busbar undervoltage scenario. Under this condition, the ATS should trigger an action, tripping the relevant switch and closing the open-loop backup switch after a delay to restore power supply. However, this traditional method has significant limitations, especially in terms of efficiency and operation time: First, the entire process requires manual operation, including adjusting the primary equipment to the required test state and disconnecting and closing switches, which is not only time-consuming but also prone to errors; second, the frequent and complex operations increase the workload of on-site operators, and the long test cycle affects the overall system operating efficiency; third, manual operation poses safety risks in high-voltage environments, especially when operators need to frequently access high-voltage equipment.

[0004] Therefore, the 110kV automatic transfer switching test method in related technologies has significant shortcomings in terms of efficiency, safety, and ease of operation, limiting the efficiency and safety of power system maintenance and commissioning. Currently, no effective solution has been proposed to address these issues. Summary of the Invention

[0005] This invention provides a remote testing method and system for the transmission of a 110kV automatic transfer switch, which at least solves the technical problem in the related art that the automatic transfer switch is often tested on-site manually before it is put into use, resulting in low testing efficiency.

[0024] In this application, the following steps are taken: First, the 110kV standby automatic transfer device to be tested is determined, and the target load station, the nearest standby load station, and the nearest open-loop point of the 110kV standby automatic transfer device to be tested are determined. Then, a transmission operation ticket is generated for the target load station and the standby load station based on the power grid dispatching platform, and the transmission operation ticket is sent to the power grid control station.

[0035] It should be noted that the remote testing method and apparatus for the 110kV automatic transfer switch transmission in this application can be used in the field of automatic transfer switch control technology for 110kV automatic transfer switch transmission tests based on remote uninterrupted power supply function, and can also be used in any field other than the field of automatic transfer switch control technology for 110kV automatic transfer switch transmission tests based on remote uninterrupted power supply function.

This avoids the complexity and time-consuming nature of manual judgment in traditional testing, significantly improving the efficiency and accuracy of the test.

[0037] The present invention will now be described in detail with reference to various embodiments.

[0038] Example 1

[0039] According to an embodiment of the present invention, a method for remote testing of a 110kV automatic transfer switch drive is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0040] Figure 1 This is a flowchart of an optional remote testing method for the transmission of a 110kV automatic transfer switch according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0041] Step S101: Determine the 110kV standby automatic transfer device to be tested, and determine the target load station, the standby load station closest to the target load station, and the open loop point closest to the target load station.

[0042] It should be noted that the 110kV automatic transfer switch (ATS) is used in multi-stage series-powered 110kV systems to activate the backup power supply at the system open-loop point when the 110kV busbar of a substation loses power, thus promptly restoring power to the lost substation busbar. To verify the correctness of the wiring and logic function of the 110kV ATS circuit and ensure its reliable operation after commissioning, a full-scale transmission test needs to be conducted before commissioning the 110kV ATS.

[0043] It should be noted that when conducting transmission tests, the 110kV automatic transfer switch (ATS) to be tested must first be identified, and the load station acting on the ATS should be designated as the target load station. The load station closest to the target load station should be designated as the backup load station. The open-loop point of the ATS needs to be located. In a power system, a load station refers to a station used to supply power to the load, such as a substation. Generally, two or more adjacent load stations serve as backups for each other. When the busbar of one load station loses voltage, the load station with the lost voltage is disconnected, the open-loop point is closed, and the backup load station is switched to supply power. This allows for rapid power restoration of the faulty distribution network, ensuring the stable operation of the power system. By determining the 110kV ATS, target load station, backup load station, and open-loop point before the experiment, automated remote testing can be performed on the ATS, accurately and quickly completing the transmission test and ensuring the normal operation of the 110kV ATS after it is put into operation.

[0044] Optionally, after determining the target load station, the nearest standby load station, and the nearest open-loop point of the 110kV automatic transfer switch to be tested, the process further includes: checking the operating status of the protection device of the target load station, checking the operating status of the 110kV automatic transfer switch of the target load station, and checking the operating status of the 110kV automatic transfer switch of the standby load station to obtain the inspection results; if the inspection results indicate that the inspection has passed, generating an inspection pass signal and sending the inspection pass signal to the power grid dispatching platform.

[0045] It should be noted that after determining the target load station, the nearest standby load station, and the nearest open-loop point of the 110kV automatic transfer switch to be tested, the power system of the target load station and the standby load station must first be checked to ensure that the protection device of the target load station is working properly and that the 110kV automatic transfer switch of the standby load station is working properly. This is a prerequisite for remotely executing the automatic transfer switch transmission test.

[0046] Optionally, the steps for checking the operating status of the protection devices of the target load station include: checking the operating status of the circuit breakers on the high-voltage side bus of the target load station, the operating status including at least one of the following: the communication status between the circuit breaker and the target load station, the operating status of the circuit breaker, the alarm information of the circuit breaker, the charging status of the reclosing of the circuit breaker, the remote operation hard switch of the circuit breaker, the remote uninterruptible power transmission soft switch of the circuit breaker, and the remote activation / deactivation soft switch of the circuit breaker.

[0047] It should be noted that the inspection of the operating status of the protection devices at the target load station is performed by the power system's main information control station. The main information control station needs to check whether the protection devices at the target load station are in normal operating condition. The protection devices here include at least the circuit breaker on the high-voltage side bus of the target load station. This circuit breaker plays a key role in simulating the busbar undervoltage of the target load station. Therefore, it is necessary to ensure that the circuit breaker can work normally before the experiment. The specific checks on the operating status of the circuit breaker can include: communication status, confirming whether the communication channel between the circuit breaker and the target load station is unobstructed and without communication abnormalities, so as to ensure that the circuit breaker on the busbar of the target load station can be remotely tripped during the subsequent test to simulate the busbar undervoltage environment; operating status, the circuit breaker should be in the operating state, i.e., the closed state, and the circuit breaker should not have any abnormal alarms or fault signals; reclosing status, for circuit breaker reclosing, it is necessary to check whether the reclosing is charging normally and whether there are any reclosing-related alarms; soft and hard pressure plates, confirming that the remote uninterruptible transmission soft pressure plate and the remote activation / deactivation hard pressure plate of the circuit breaker are in the correct activation / deactivation state to ensure the feasibility of remote operation.

[0048] Optionally, the steps for checking the operating status of the 110kV automatic transfer switch of the target load station include: checking the charging status of the 110kV automatic transfer switch of the target load station; checking the alarm information of the operating status of the 110kV automatic transfer switch of the target load station; comparing the device data of the 110kV automatic transfer switch of the target load station with the device data in the setting sheet; and checking the activation / deactivation status of the soft pressure plate of the 110kV automatic transfer switch of the target load station.

[0049] It should be noted that the check of the operating status of the 110kV automatic transfer switch at the target load station is performed by the power system's safety control station. The safety control station communicates with the automatic transfer switches at each load station to check their operating status, specifically including: checking the charging status of the 110kV automatic transfer switch at the target load station (a charging status indicates the switch is ready and can automatically start); checking the alarm information of the 110kV automatic transfer switch at the target load station to ensure there are no potential faults or abnormalities; and checking whether the device data of the 110kV automatic transfer switch at the target load station matches the data in the setting sheet. Consistency is key. The setting sheet contains preset parameters for the automatic transfer switch (ATS), such as voltage threshold and time delay. These parameters determine the conditions under which the device operates. Comparing the current configuration data of the ATS with the setting sheet confirms whether the device settings are correct and consistent with the expected test conditions. If inconsistencies are found, adjustments are needed to ensure the accuracy of the test conditions. Finally, the activation / deactivation status of the soft switch of the 110kV ATS at the target load station needs to be checked. The soft switch is a logic switch that controls the activation or deactivation of the ATS function. The soft switch for remote operation needs to be in the activated state so that it can be remotely controlled through the main station.

[0050] Optionally, the steps for checking the operating status of the 110kV automatic transfer switch of the standby load station include: checking the charging status of the 110kV automatic transfer switch of the standby load station; checking the alarm information of the operating status of the 110kV automatic transfer switch of the standby load station; comparing the device data of the 110kV automatic transfer switch of the standby load station with the device data in the setting sheet; and checking the activation / deactivation status of the soft pressure plate of the 110kV automatic transfer switch of the standby load station.

[0051] Similarly, before conducting formal transmission tests, the Anzhi substation needs to check the operating status of the 110kV automatic transfer switch of the standby load station, which is the same as the check of the 110kV automatic transfer switch of the target load station. The specific checks on the operating status of the 110kV automatic transfer switch of the standby load station include: checking whether the 110kV automatic transfer switch of the standby load station is in charging state; checking whether there are any alarm messages in the operating status of the 110kV automatic transfer switch of the standby load station; checking whether the device data of the 110kV automatic transfer switch of the standby load station is consistent with the data configured in the setting sheet; and checking whether the soft pressure plate of the 110kV automatic transfer switch of the standby load station is in the engaged state, thereby ensuring that the 110kV automatic transfer switch of the standby load station is available.

[0052] Step S102: Generate transmission operation tickets for the target load station and the standby load station based on the power grid dispatching platform, and send the transmission operation tickets to the main station of the power grid dispatching platform.

[0053] It should be noted that the safety control station and the security information control station upload the inspection results to the power grid dispatching platform. If the inspection is confirmed to be problem-free, the power grid dispatching platform generates transmission operation tickets for the target load station and the standby load station, and sends the transmission operation tickets to the security information control station to realize intelligent dispatching and control of the power grid. The power grid dispatching platform is deployed in the control center and can be used to generate operation tickets and send operation instructions to the dispatch automation system to complete primary equipment control, send operation instructions to the security information control station to complete the control of protection devices, and send operation commands to the safety control station to complete the control of safety control devices. The transmission operation ticket contains transmission test instructions, which are used to control the security information control station to execute transmission test instructions to simulate the test environment of bus undervoltage of the target load station.

[0054] Step S103: Execute the transmission operation ticket based on the main station of the information security system.

[0055] It should be noted that the transmission operation ticket is used to control the primary equipment of the target load station and the standby load station based on the main station of the power supply and control system, thereby tripping the switch of the target load station, causing the busbar of the target load station to lose voltage, and thus conducting a transmission test on the 110kV standby automatic transfer device.

[0056] Optionally, the steps of executing the transmission operation ticket based on the main station of the power supply and information technology bureau include: removing the reclosing soft pressure plate of the high-voltage side bus circuit breaker of the target load station based on the main station of the power supply and information technology bureau; and executing the transmission command on the high-voltage side bus circuit breaker of the target load station based on the main station of the power supply and information technology bureau, so that the high-voltage side bus circuit breaker of the target load station is in the open position.

[0057] It should be noted that, based on the transmission test command in the transmission operation ticket, the main station of the power supply and control station first disconnects the reclosing soft pressure plate of the high-voltage side bus circuit breaker of the target load station to prevent the reclosing function from automatically closing the circuit breaker after it is tripped, thus affecting the normal operation of the 110kV standby automatic transfer switch. Secondly, it is necessary to execute the transmission command on the high-voltage side bus circuit breaker of the target load station to trip the circuit breaker switch, so that the circuit breaker is in the open position, thereby simulating the scenario of the target load station bus losing voltage.

[0058] Optionally, after executing the transmission operation ticket based on the main station of the power supply and control system, the process further includes: determining the execution result of the transmission operation ticket based on the automatic transfer switch action criteria; and determining that the transmission operation ticket execution has ended if the power system where the target load station and the standby load station are located meets the automatic transfer switch action criteria.

[0059] It should be noted that after simulating the scenario of busbar undervoltage at the target load station, the power system where the target load station and the standby load station are located is judged by the pre-set standby automatic transfer action criteria to determine whether the transmission operation ticket has been executed and whether the simulated busbar undervoltage scenario meets the expected requirements.

[0060] Optionally, the automatic transfer switch (ATS) operation criteria include at least one of the following: the circuit breaker position signal of the target load station is inconsistent with the closed switch position signal; the voltage signal of the bus in the power system other than the bus of the target load station meets the reclosing waveform; the negative sequence voltage of the bus in the power system other than the bus of the target load station is greater than the negative sequence voltage threshold of the fault bus in the target time period; and the zero sequence voltage of the bus in the power system other than the bus of the target load station is greater than the zero sequence voltage threshold of the fault bus in the target time period.

[0061] Specifically, the power system is considered to have successfully executed the transmission operation ticket if at least one of the following conditions is met: First, the circuit breaker position signal of the target load station is inconsistent with the closed switch position signal, that is, in the simulation environment, the bus circuit breaker of the target load station is in the open position; Second, the voltage of any non-maintenance bus in the power system meets the reclosing waveform. The waveform discrimination conditions are as follows: First, the bus voltage should meet the process of "voltage present → voltage absent → voltage present", that is, after the three-phase voltage of the bus is lower than the voltage absent value for more than the first time delay, within the start-up delay Tq of the 110kV automatic transfer switch, the voltage of any phase of any bus is higher than 0.5Un for more than the second time delay, where Un represents the rated voltage of the bus. Second, within at least the second time delay, the negative sequence voltage of any non-maintenance bus is greater than the negative sequence voltage threshold of the fault bus. When a fault occurs in the power system, a negative sequence voltage may be generated. By checking the negative sequence voltage of any non-maintenance bus, it is ensured that the power system will not affect the start-up of the 110kV automatic transfer switch. Third, within at least the second time delay, the zero sequence voltage of any non-maintenance bus is greater than the zero sequence voltage threshold of the fault bus, thereby ensuring that the 110kV automatic transfer switch can start normally.

[0062] Step S104: After the transmission operation ticket is executed, check the status of the open loop point and the bus voltage of the target load station. Based on the status of the open loop point and the bus voltage of the target load station, determine the transmission test results of the 110kV automatic transfer switch of the target load station and the 110kV automatic transfer switch of the standby load station.

[0063] It should be noted that, under normal circumstances, when the 110kV automatic transfer switch detects the busbar voltage loss at the target load station, it will automatically switch to the backup power supply to power the load. In order to obtain the transmission test results of the automatic transfer switch, after the transmission operation ticket is executed, the open-loop circuit breaker and the busbar voltage of the target load station are checked to determine whether the 110kV automatic transfer switch has been successfully started.

[0064] Optionally, the step of checking the status of the open-loop point and the bus voltage of the target load station, and determining the transmission test results of the 110kV automatic transfer switch of the target load station and the 110kV automatic transfer switch of the standby load station based on the status of the open-loop point and the bus voltage of the target load station includes: acquiring the circuit breaker position signal of the open-loop point and comparing the circuit breaker position signal with the closed switch position signal to obtain a first comparison result; acquiring the bus voltage of the target load station and comparing the bus voltage with the fault bus voltage threshold to obtain a second comparison result; determining the transmission test results of the 110kV automatic transfer switch of the target load station and the 110kV automatic transfer switch of the standby load station based on the first comparison result and the second comparison result, wherein, if the first comparison result indicates that the circuit breaker position signal is consistent with the closed switch position signal and the bus voltage is greater than the fault bus voltage threshold, it is determined that the 110kV automatic transfer switch of the target load station and the 110kV automatic transfer switch of the standby load station have passed the transmission test.

[0065] It should be noted that when verifying the results of the transmission test, the circuit breaker position information at the open loop point is first obtained to determine whether the circuit breaker position signal is consistent with the closed switch position signal. The bus voltage of the target load station is also collected to determine whether the bus undervoltage fault of the target load station has been recovered. If the circuit breaker position signal is consistent with the closed switch position signal and the bus voltage is greater than the fault bus voltage threshold, it indicates that the 110kV standby automatic transfer device has been successfully started in the simulated environment and can be put into operation in the actual scenario, thus obtaining the test results of the 110kV standby automatic transfer device passing the transmission test.

[0066] In another embodiment, when the 110kV standby automatic transfer device passes the transmission test, the transmission test results are uploaded to the distribution network dispatching platform. The distribution network dispatching platform generates a restoration operation ticket and sends the restoration operation ticket to the power supply and information control main station. The power supply and information control main station executes the restoration command and puts the soft pressure plate of the circuit breaker reclosing outlet on the high-voltage side bus of the target load station into operation. This allows the reclosing to automatically restore the disconnected circuit breaker switch, relieve the simulated busbar undervoltage environment, and allow the power system to return to normal.

[0067] Through the above steps, the 110kV standby automatic transfer switch to be tested is first determined, along with the target load station, the nearest standby load station, and the nearest open-loop point. Based on the power grid dispatch platform, transmission operation tickets are generated for the target load station and the standby load station, and these tickets are then sent to the main power grid control station. The main power grid control station then executes the transmission operation tickets. Finally, after the execution of the transmission operation tickets, the status of the open-loop point and the bus voltage of the target load station are checked. Based on the status of the open-loop point and the bus voltage of the target load station, the transmission test results of the 110kV standby automatic transfer switch at the target load station and the 110kV standby automatic transfer switch at the standby load station are determined.

[0068] In this embodiment, a transmission operation ticket is generated through the one-click sequential control function of the power grid dispatching platform in the power grid dispatching system and sent to the power supply and information control main station. The operation ticket is executed through the remote uninterrupted power transmission function of the power supply and information control main station to remotely control the primary equipment of the target load station and the standby load station, simulating the power system bus undervoltage environment. This allows for remote automatic transmission testing of the 110kV automatic transfer switch, realizing the automation of the automatic transfer switch transmission test. This avoids the complexity and time-consuming nature of manual judgment in on-site testing, improves test efficiency, reduces operational errors, and enhances the reliability of test results. This solves the technical problem in related technologies where, before the 110kV automatic transfer switch is put into use, it is often tested manually on-site, resulting in low testing efficiency.

[0069] The following describes in detail another optional implementation method.

[0070] The remote testing method for the transmission of 110kV automatic transfer switch (ATS) devices according to this invention is applied to a remote testing system for the transmission of 110kV ATS devices. Besides 110kV power systems, this invention can also be used to conduct transmission tests on ATS devices in other power systems. Figure 2 This is an optional primary wiring diagram of a power system according to an embodiment of the present invention, such as... Figure 2As shown, on the 110kV busbar, stations A and D are power supply stations, while stations B and C are backup load stations for each other. Stations A and B are connected via line AB, stations B and C are connected via line BC, and stations C and D are connected via line CD. With the position of circuit breaker BC as the open loop point, circuit breaker BC at station B is open, and circuit breaker CB at station C is closed. Station B is powered by station A via line AB, and station C is powered by station D via line CD. Stations B and C are each equipped with a 110kV automatic transfer switch (ATS) device. Its operating logic is as follows: When Station C detects no voltage on the 110kV busbar and no current on the main supply line, and meets the KRU condition (corresponding to the aforementioned ATS action criterion), the Station C 110kV ATS is activated. After a delay, the Station C CD circuit breaker trips. The ATS device detects that the CD circuit breaker has tripped and, after a delay, sends a remote closing command to the Station B 110kV ATS device via the channel. The Station B 110kV ATS device then closes the Station B BC circuit breaker, switching power supply to Station B and restoring power supply to Station C.

[0071] Figure 3 This is an architecture diagram of an optional 110kV automatic transfer switch drive remote testing system according to an embodiment of the present invention, as shown below. Figure 3 As shown, the remote testing system for the 110kV automatic transfer switch includes: a DICP system, a firewall, a protection and information system, an automatic safety system, and a remote control system. The DICP system communicates with the automatic safety system, the protection and information system, and the remote control system via the firewall. The automatic safety system consists of automatic safety stations, which connect to the 110kV automatic transfer switches at load stations in the power system via the dispatch data network. The protection and information system consists of a main protection and information station and several protection and information substations deployed in the power system, connecting to the protection devices in the power system. The remote control system consists of an OSC system, which connects to the measurement and control devices at various power stations or load stations via remote control units deployed in the power system. Specifically…

[0072] OCS (Operating Control System) refers to the Dispatch Automation System, deployed in the control center. It is a system that directly collects and monitors data for power grid operation. It can monitor the operating status of primary equipment (switches, disconnectors, etc.) in real time and complete the operation of primary equipment. It communicates with remote control units deployed in substations through the dispatch data network, and then controls the protection devices of the substations through the remote control units.

[0074] The main station of the protection system is deployed in the control center and connects to the substations of the protection system through the dispatch data network. It collects data from the protection equipment in real time and completes the operation of the protection equipment through the substations of the protection system. It can realize operations such as remote activation and deactivation of soft pressure plates, remote modification of set values, and remote uninterrupted power transmission of the protection device.

[0075] Remote uninterrupted power transmission refers to the process where the main power supply station sends a transmission command to the protection device, and the protection device completes the protection tripping and reclosing of the switch after receiving the command. The entire process can be executed remotely without causing power outages for users.

[0076] The automatic transfer station is deployed in the control center and communicates with the 110kV standby automatic transfer device of the load station through the dispatch data network. It is used to forward the remote control commands of the low-frequency low-voltage load shedding device issued by the DICP system and has functions such as remotely activating and deactivating soft pressure plates and remotely modifying setpoints.

[0077] The protection information substation includes intelligent waveform recorders, control substations, etc., and is deployed in the substation. It is used to forward the data of the protection device to the protection information master station, and forward the remote activation / deactivation soft switch, remote setting modification, and remote non-power-off transmission commands of the protection information master station to the protection device.

[0078] The data from the protection device includes analog quantities, input quantities, soft pressure plates, set values, alarm information, etc.

[0079] Remote control units (RTUs) are deployed in substations and can perform functions such as remote control, remote signaling, remote measurement, and remote adjustment.

[0080] The remote testing system for the drive of a 110kV automatic transfer switch according to this invention is used to perform a remote testing method for the drive of a 110kV automatic transfer switch. Figure 4 This is a schematic diagram of an optional remote testing process for a 110kV automatic transfer switch drive according to an embodiment of the present invention. Figure 2 Station C is the target load station for this test, and station B is the backup load station. Figure 4 As shown, the transmission test steps before the automatic switching device is put into use include:

[0081] Step 1, Initialization;

[0082] Step 2: The OSC system checks whether the open loop point is at station B. If yes, proceed to step 3. If no, adjust the open loop point to station B and then proceed to step 2 again.

[0083] Step 3: The main station of the security system checks whether the protection device (i.e., CD circuit breaker) of the CD line of station C is operating normally and whether the reclosing is charging normally. If yes, proceed to step 4. If no, check and handle the protection device of CD line of station C and then proceed to step 3 again.

[0084] Step 4: Check whether the automatic transfer switches of stations B and C are operating normally and whether they are charging normally. If yes, proceed to step 5. If not, check and handle the automatic transfer switches of stations B and C and then proceed to step 4 again.

[0085] Step 5: The DICP system generates a test operation ticket for the 110V standby automatic transfer device and sends it to the main station of the security information system.

[0086] Step 6, Baoxin main station executes operation ticket: Exit CD line protection device reclosing output soft pressure plate;

[0087] Step 7, Baoxin main station executes operation ticket: remote uninterruptible power transmission trips C station CD line switch (i.e. CD circuit breaker);

[0088] Step 8: Check whether the automatic transfer switches of stations B and C are operating correctly: Check whether the BC switch of station B is closed and whether the bus voltage of station C has been restored. If yes, proceed to step 9; otherwise, skip step 9 and proceed to step 10.

[0089] Step nine: The automatic transfer devices at stations B and C are successfully activated.

[0090] Step 10: The automatic transfer device at stations B and C failed to operate.

[0091] Step 11, Baoxin main station executes operation ticket: Activate the reclosing output soft pressure plate of the protection device for C station CD line.

[0092] In this embodiment of the invention, a transmission operation ticket is issued to the main station of the power grid dispatching platform through the one-click sequential control function. The primary equipment in the target load station and the standby load station is controlled through the remote uninterrupted transmission function of the main station of the power grid dispatching platform. The main power supply switch of the non-open loop substation is tripped, and the busbar undervoltage environment is simulated remotely. This realizes the 110kV standby automatic transfer automatic transmission test, avoiding the complexity and time-consuming nature of manual judgment in traditional tests, and significantly improving the efficiency and accuracy of the test.

[0093] The following is a detailed description with reference to another embodiment.

[0094] Example 2

[0095] The remote testing system for the transmission of a 110kV automatic switching device provided in this embodiment includes multiple implementation units. Each implementation unit corresponds to a specific implementation step in the above embodiment one. The specific implementation method and beneficial effects can be referred to the aforementioned method embodiment, and will not be repeated here.

[0096] Figure 5 This is a schematic diagram of a remote testing system for an optional 110kV automatic transfer switch drive according to an embodiment of the present invention, as shown below.

The system then generates transmission operation tickets for the target load station and the standby load station through the power grid dispatch platform 52. The system receives and executes the transmission operation tickets from the power grid dispatch platform through the security and information control master station 53. After the transmission operation tickets are executed, the system checks the status of the open-loop point and the bus voltage of the target load station through the safety and security master station 54, and determines the transmission test results of the 110kV ATS at the target load station and the 110kV ATS at the standby load station based on these parameters.
