[0002] The stabilization control device (system) is the second line of defense to ensure the safety and stability of the power system. 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 failure of the stabilization control device to operate has been the primary risk in the operation of the power grid over the years. The switch transmission of the stabilization control device is an important measure to prevent the failure of the stabilization control device to operate.

[0049] The embodiment of the present invention provides a remote non-stop power transmission system and method for a stabilization control device, which is used to solve or partially solve the technical problems of long export transmission verification period, low efficiency and heavy operation workload.

[0050] 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.

[0051] As an example, the existing stabilization and control devices are constrained by functions and secondary circuits. Since the standard configuration has 16 load shedding outlets, the export transmission requires load interval power outages and cannot be shut down at multiple intervals at one time, resulting in a long verification period for all exports and low efficiency. The existing export transmission verification method not only easily leads to a large workload for on-site operation and maintenance personnel to shut down power, but also brings risks to the power grid caused by equipment power outages. At present, there is no effective technical solution for remote non-stop transmission of stabilization and control devices.

[0052] 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 remote non-stop power transmission system and method for a stabilization control device is provided. In the remote non-stop power transmission system, information is exchanged between modules such as the stabilization control device, the safety main station, the OCS automation main station and the DICP main station. The safety main station performs a remote non-stop power transmission wheel-cut cycle by coordinating the stabilization control device, the DICP main station and the OCS automation main station. The safety main station remotely transmits the load interval of the stabilization control device export, and synchronously generates a closing operation ticket for the load interval at the DICP main station, and realizes automatic closing after the stabilization control device exports. Therefore, on the basis of the existing stabilization control device function, the master station remote control method is adopted to realize efficient non-stop power transmission of the stabilization control device, greatly shorten the export transmission verification cycle, and reduce the operating workload. During the export transmission process, the safety main station analyzes the non-stop power transmission results of the stabilization control device in real time throughout the whole process, and summarizes the non-stop power transmission export results of all load intervals, thereby effectively improving the timeliness of the export transmission test of the stabilization control device and the reliability of the power grid operation, and building a reliable stabilization control and anti-rejection system.

[0053] Reference Figure 1 , showing a schematic structural diagram of a remote non-stop power transmission system of a stabilization control device provided by an embodiment of the present invention.

[0054] Combination Figure 1 The remote non-stop power transmission system mainly includes an autonomous station 101, a DICP master station 102, a stabilization control device 103 and an OCS automation master station 104 respectively connected to the autonomous station 101. Among them, the DICP master station 102 is connected to the autonomous station 101 and the OCS automation master station 104 respectively through a forward / reverse isolation device 105. The OCS automation master station 104 is connected to the autonomous station 101 through a firewall 106. The autonomous station 101 is connected to the stabilization control device 103 at the substation end through a dispatching data network 107. In addition, the remote non-stop power transmission system also includes a motion machine 108 connected to the OCS automation master station 104 through a dispatching data network 107, and a measurement and control device 109 connected to the motion machine 108. The stabilization control device 103 and the measurement and control device 109 are respectively connected to a circuit breaker operation box 1010. The circuit breaker operation box 1010 is connected to the circuit breaker structure. One end of the circuit breaker structure is connected to the measurement and control device 109.

[0055] To facilitate flow control, the embodiment of the present invention divides the remote non-stop power transmission system into zones based on the power system monitoring network specification. It is mainly divided into zone I, zone II (zone I and zone II can be understood as the dispatching master station side) and station end (referring to the substation side, which can also be called the substation end).

[0056] Among them, Zone I and Zone II are divided based on the real-time transmission of business. Various master stations in Zone I and Zone II are deployed in the control center to centrally control the equipment of the substation at the lower station end. Zone I is a real-time zone, which is responsible for the most critical and real-time data transmission of the power system and needs to receive or feedback information immediately. Zone I has high transmission real-time requirements, generally in milliseconds or seconds. Zone II is a non-real-time zone with low transmission real-time requirements. It is generally used for operation and maintenance personnel to transmit instructions such as control operations. Since the DICP master station 102 is used for operation instruction transmission, the data flow is small and the real-time performance does not meet the millisecond requirement. Therefore, the DICP master station 102 is set in Zone II. Therefore, for the sake of flow control and network monitoring, more standardized site and network management can be achieved by further zoning the remote non-stop transmission system.

[0057] DICP Master Station 102 (Distributed Intelligent Control Platform Master Station) refers to the dispatching intelligent operation platform. It can be understood as a central management node of a distributed intelligent control platform. DICP Master Station 102 can be used to compile operation tickets (Operation Ticket or Work Order) related to primary and secondary equipment in substations. Specifically, DICP Master Station 102 can realize functions such as operation ticket generation, operation order sending, and operation result verification.

[0058] The OCS automation master station 104 (Operational Control System Master Station) refers to the master station of the power grid dispatching automation system. It can be understood as a central platform for centralized monitoring, control and management of distributed automation systems. The OCS automation master station 104 can receive telesignal quantities and telemetering quantities sent by the remote motor at the substation end. It can also forward the operation commands issued by the DICP master station 102 to realize remote control operation of the circuit breaker at the substation end.

[0059] The safety master station 101 refers to the main management station of the safety automatic equipment. The safety master station 101 can query the status of the safety automatic equipment such as the substation end stabilization control device 103, remotely modify and query the setting value of the safety automatic equipment, and remotely control the safety automatic equipment to execute the export.

[0060] The telemotor is a device that realizes communication between the dispatching master station and the substation. It is mainly used to realize remote monitoring, remote control and other functions.

[0061] The measurement and control device 109 refers to a substation-side information collection and remote control execution device. The measurement and control device 109 is mainly used to collect analog and switch signal of substation-side equipment and remotely control primary equipment.

[0062] The stabilization control device 103 refers to a device for controlling the stability of parameters such as voltage and frequency of the power system. When the power system encounters disturbances, the stabilization control device 103 can realize the function of load shedding.

[0063] The circuit breaker operation box 1010 is used to complete the circuit breaker opening and closing operations and the circuit breaker associated signal output.

[0064] The circuit breaker mechanism 1011 refers to a mechanical system that realizes the opening and closing of the circuit breaker and reflects the status of the circuit breaker.

[0065] Based on the content introduced above, in the remote non-stop power transmission process of the stabilization and control device, the main functions implemented by the main station 101 are: receiving the non-stop power transmission task issued by the DICP master station 102 to the stabilization and control device 103, and matching the task according to the non-stop power transmission task; when the task matching is successful and the state of the stabilization and control device 103 is judged to be normal, obtaining the constant file of the stabilization and control device 103; remotely controlling the non-stop power transmission enabling soft pressure plate of the stabilization and control device, if successfully put into operation, the coordinated stabilization and control device 103, the DICP master station 102 and the OCS automation master station 104 will execute the remote non-stop power transmission wheel-cutting cycle; when the number of wheel-cutting reaches the number corresponding to the constant file, the wheel-cutting cycle is ended, and the non-stop power transmission enabling soft pressure plate of the stabilization and control device is exited.

[0066] Specifically, after the DICP master station 102 selects a specific stabilization and control device and writes a task, it starts the process of issuing the non-stop power transmission task of the stabilization and control device. After the main station 101 receives the non-stop power transmission task, it confirms whether all the task items are matched according to the non-stop power transmission task. Among them, the main station 101 needs to confirm that the matching task items include the substation where the stabilization and control device is located, the model of the stabilization and control device, and the device setting number. When all the task items are matched (that is, the substation where the stabilization and control device is located, the model of the stabilization and control device, and the device setting number are all matched successfully), continue to execute the next step of the stabilization and control device status judgment action. When there is a mismatch in the task items, the current non-stop power transmission task is terminated.

[0067] When all the task items are matched, the main station 101 obtains the operating status (i.e., status information) sent by the stabilization and control device 103. Then, the main station 101 determines whether the stabilization and control device 103 at the substation end is normal according to the preset judgment conditions. When making a judgment, the set judgment conditions must be met, and the system will determine that the operating status of the stabilization and control device 103 is normal. Only when the operating status of the stabilization and control device 103 is normal will the next step be performed, otherwise the abnormal status will be recorded. In other words, when the operating status of the stabilization and control device 103 meets the preset judgment conditions, it is determined that the stabilization and control device 103 is in a normal state, and the next step of the stabilization and control device 103 constant value file acquisition action is performed. When the operating status of the stabilization and control device 103 does not meet the preset judgment conditions, the abnormal status is recorded.

[0068] Among them, the status judgment conditions of the stabilization control device 103 include the following: the communication of the stabilization control device is normal, there is no alarm information of the stabilization control device, the non-stop transmission function of the stabilization control device is not enabled, and the state and fixed value of the pressure plate of the stabilization control device are consistent with the device fixed value list. In other words, when the stabilization control device 103 satisfies the normal communication, no alarm information, the non-stop transmission function is not enabled, and the state and fixed value of the pressure plate are consistent with the device fixed value list, the operation state of the stabilization control device 103 meets the preset judgment conditions.

[0069] The stabilization control device 103 stores the corresponding fixed value file (fixed value list). The fixed value file is a unified standard format file that covers all the information of the fixed value list of the stabilization control device. After the main station 101 sends a fixed value file information acquisition instruction, the fixed value file stored in the substation-end stabilization control device 103 can be obtained through the dispatching data network 107. After receiving the fixed value file, the main station 101 interprets it and obtains the contents in the fixed value list.

[0070] In a specific implementation, when it is determined that the stabilization device 103 is in a normal state, the main station 101 obtains the fixed value file of the stabilization device 103 specified by the task, and then parses it to confirm the number of wheel shedding load intervals of the stabilization device 103. The number of wheel shedding load intervals refers to the number of load intervals of the set output in the fixed value file of the stabilization device, which can be confirmed according to the soft pressure plate throw-in and throw-out conditions. Figure 2 shown. Figure 2 The number of load shedding intervals corresponding to the stabilizing device 103 shown in the figure is 2, and the load shedding objects are 110kV Difeng A line and 110kV Difeng B line in sequence.

[0071] Then, the main station 101 activates the non-stop power transmission enabling soft pressure plate of the stabilization and control device, and determines whether it is successfully activated. Specifically, the main station 101 remotely controls the activation of the non-stop power transmission enabling soft pressure plate of the stabilization and control device 103 corresponding to the non-stop power transmission task, and determines whether it is successfully activated after remote control. If it is successfully activated, the task will continue to be executed. Otherwise, the failure will be recorded. The non-stop power transmission enabling soft pressure plate refers to the soft pressure plate used by the stabilization and control device 103 to determine whether the device enters the non-stop power transmission mode. After the non-stop power transmission enabling soft pressure plate is successfully activated, the stabilization and control device 103 can enter the non-stop power transmission exit execution menu.

[0072] After the non-stop power transmission enabling soft pressure plate is successfully put into use, combined with the analysis and processing of the fixed value file, the safety master station 101 is used as the execution subject to coordinate the stabilization control device 103, the DICP master station 102 and the OCS automation master station 104 to execute the remote non-stop power transmission wheel switching cycle. The specific steps are as follows:

[0073] Step 1: confirm the number of wheel shedding load intervals of the stabilization control device 103 according to the fixed value file.

[0074] Step 2: Initialize the current wheel cutting interval sequence number, wherein the initialized wheel cutting interval sequence number is 1.

[0075] Step 3, determine the relationship between the current wheel cutting interval number and the wheel cutting load interval number. The specific size determination condition is: if the current wheel cutting interval number ≤ wheel cutting load interval number, continue the cycle, otherwise end the cycle and exit the non-power-off transmission enabling soft pressure plate of the stabilization control device.

[0076] Step 4: When the current wheel shedding interval sequence number is less than or equal to the wheel shedding load interval number, generate an operation ticket instruction for closing the current wheel shedding object switch.

[0077] Step 5, send the instruction to generate an operation ticket to the DICP master station 102, so that the DICP master station 102 generates an operation ticket for the switching object according to the instruction to generate an operation ticket. The DICP master station 101 sends the instruction to generate an operation ticket to the DICP master station 102, and the DICP master station 102 generates the corresponding operation ticket for the switching object after receiving the instruction. The operation ticket content of the switching object at the DICP master station 102 is: remote control closing + substation name + switching object interval name + switching object interval number. For example: remote control closing 220kV Diguang station 110kV Difeng A line switch 1175.

[0078] Step 6: Generate a transmission output instruction for the current wheel cutting object according to the current wheel cutting interval sequence number.

[0079] Step 7: Send the transmission exit instruction to the stabilization control device 103, so that the stabilization control device 103 executes the transmission exit based on the transmission exit instruction. Steps 6 and 7 are mainly used to implement the transmission exit of the remote part of the wheel-cutting object without power outage. The main station 101 sends the transmission exit instruction of the wheel-cutting object according to the wheel-cutting interval sequence number, and the stabilization control device 103 executes the transmission exit after receiving the instruction.

[0080] Step 8, receiving the message information during the transmission period forwarded by the OCS automation master station 104, and judging whether the current wheel-cutting object meets the stable control disconnection criterion according to the message information. More specifically, the OCS automation master station 104 receives the message information during the transmission period sent by the measurement and control device 109 via the motion machine 108, and transmits the message information to the safety master station 101 via the firewall 106, so that the safety master station 101 can judge whether the current wheel-cutting object meets the stable control disconnection criterion according to the message information. Among them, the stable control disconnection criterion is to simultaneously meet the switch position of the current wheel-cutting object is open, the current wheel-cutting object has no current, and there is no protection action message at the station end where the stable control device is located.

[0081] Step 9: When the current wheel cutting object meets the stable control disconnection criterion, record the transmission success interval and generate a remote control closing operation ticket execution instruction. When the current wheel cutting object does not meet the stable control disconnection criterion, record the transmission abnormal interval.

[0082] Step 10, send the remote control closing operation ticket execution instruction to the DICP master station 102, so that the DICP master station 102 executes the switch object operation ticket according to the remote control closing operation ticket execution instruction, and controls the OCS automation master station 104 to remotely close the current switch object. After the main station 101 determines that the current switch object meets the stable control disconnection criterion, it sends the remote control closing operation ticket execution instruction to the DICP master station 102. After receiving the instruction, the DICP master station 102 executes the operation ticket. After receiving the operation execution instruction, the OCS automation master station 104 remotely closes the switch of the switch object.

[0083] Step 11. When the current wheel-cutting object is successfully closed, the wheel-cutting interval number is superimposed, and the step of judging the relationship between the current wheel-cutting interval number and the wheel-cutting load interval number is returned, and the wheel-cutting cycle is continued until the current wheel-cutting interval number is greater than the wheel-cutting load interval number. After the OCS automation master station 104 executes the remote control closing operation, it is determined whether the remote control is successful (i.e., whether the wheel-cutting object switch is closed). When the switch position changes to the closed position after remote control, it indicates that the closing is successful. The main station 101 performs the wheel-cutting interval number superposition. The superimposed wheel-cutting interval number is (the current wheel-cutting interval number + 1), and returns to the loop judgment condition (i.e., step 3). Otherwise, the abnormal remote control interval is recorded.

[0084] When the wheel cutting cycle is completed, the non-stop transmission of the corresponding stabilization control device enables the soft pressure plate of the remote remote control exit task of the autonomous station 101.

[0085] Furthermore, when the autonomous station 101 remotely controls the exit of the non-stop power transmission enabling soft pressure plate of the stabilization control device, it can autonomously summarize the record results output by each process node, generate a work record of the non-stop power transmission task, and store the work record.

[0086] In an embodiment of the present invention, a remote non-stop power transmission system for a stabilization control device is provided. In the system, information is exchanged between modules such as the stabilization control device, the safety main station, the OCS automation main station and the DICP main station. The safety main station performs a remote non-stop power transmission wheel-cut cycle by coordinating the stabilization control device, the DICP main station and the OCS automation main station. The safety main station remotely transmits the load interval of the stabilization control device export, and synchronously generates a closing operation ticket for the load interval at the DICP main station, and realizes automatic closing after the stabilization control device exports. Therefore, on the basis of the existing stabilization control device function, the master station remote control method is adopted to realize efficient non-stop power transmission of the stabilization control device, greatly shorten the export transmission verification cycle, and reduce the operating workload. During the export transmission process, the safety main station analyzes the non-stop power transmission results of the stabilization control device in real time throughout the whole process, and summarizes the non-stop power transmission export results of all load intervals, thereby effectively improving the timeliness of the export transmission test of the stabilization control device and the reliability of the power grid operation, and building a reliable stabilization control and anti-rejection system.

[0087] Reference Figure 3 , shows a flowchart of the steps of a remote non-stop power transmission method of a stabilization control device provided by an embodiment of the present invention, the method is applied to the remote non-stop power transmission system of the stabilization control device as described in the above embodiment; the remote non-stop power transmission method may specifically include the following steps:

[0088] Step 301, the security master station receives the non-stop power transmission task issued by the DICP master station for the stabilization control device, and performs task matching according to the non-stop power transmission task;

[0089] Step 302, when the task matching is successful and the state of the stabilization control device is judged to be normal, the security main station obtains the fixed value file of the stabilization control device;

[0090] Step 303, the automation master station remotely controls the activation of the non-stop power transmission soft pressure plate of the stabilization control device. If the activation is successful, the automation master station cooperates with the stabilization control device, the DICP master station and the OCS automation master station to perform a remote non-stop power transmission wheel switching cycle;

[0119] As for the method embodiment, since it is basically similar to the system embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the aforementioned system embodiment.

[0120] In an embodiment of the present invention, a method corresponding to a remote non-stop power transmission system of a stabilization and control device is provided. The information between modules such as the stabilization and control device, the safety main station, the OCS automation main station and the DICP main station is exchanged. The safety main station performs a remote non-stop power transmission wheel-cut cycle by coordinating the stabilization and control device, the DICP main station and the OCS automation main station. The load interval of the stabilization and control device is remotely transmitted by the safety main station, and the closing operation ticket of the load interval is synchronously generated at the DICP main station, and the stabilization and control device is automatically closed after the export. Therefore, on the basis of the existing stabilization and control device function, the master station remote control method is adopted to realize efficient non-stop power transmission of the stabilization and control device, greatly shorten the export transmission verification cycle, and reduce the operating workload. During the export transmission process, the safety main station analyzes the non-stop power transmission results of the stabilization and control device in real time throughout the whole process, and summarizes the non-stop power transmission export results of all load intervals, thereby effectively improving the timeliness of the export transmission test of the stabilization and control device and the reliability of the power grid operation, and building a reliable stabilization and control anti-rejection system.

[0121] For better explanation, refer to Figure 4 , showing an overall flow chart of a method for remote non-stop power transmission 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 remote non-stop power transmission of a 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.

[0122] Step 401, the DICP master station starts the process of issuing the non-stop power transmission task of the stabilization control device, and issues the non-stop power transmission task; and then proceeds to step 402.

[0123] Step 402: After receiving the non-stop power transmission task, the main station confirms whether all task items match according to the non-stop power transmission task; if so, jump to step 403; if not, jump directly to step 4015.

[0124] Step 403, the main station obtains the operating status sent by the stabilization and control device, and judges whether the stabilization and control device at the substation end is normal according to the preset judgment conditions; if so, jump to step 404; if not, record the cause of the abnormal state and jump to step 4014.

[0125] Step 404, the installation station obtains the constant value file of the stabilization control device, obtains the number of load shedding intervals of the stabilization control device through analysis, and puts the soft pressure plate of the non-stop transmission of the stabilization control device into operation; and continues to execute step 405.

[0126] Step 405, the autonomous station determines whether the non-power-off transmission enabling soft pressure plate of the stabilization control device is successfully put into operation; if so, jump to step 406; if not, record the abnormality of the soft pressure plate being put into operation and jump to step 4014.

[0127] Step 406 : The main station initializes the current shear interval sequence number, wherein the initialized shear interval sequence number is 1. Then proceed to step 407 .

[0128] Step 407, determine whether the current wheel cutting interval number is less than or equal to the wheel cutting load interval number; if so, continue the loop and jump to step 408; if not, end the loop, install the self-station exit stabilization control device non-stop transmission enable soft pressure plate, and jump to step 4014.

[0129] Step 408, the main station generates a generate operation ticket instruction for closing the current switch of the rotation switching object, and sends the generate operation ticket instruction to the DICP main station, so that the DICP main station generates a rotation switching object closing operation ticket according to the generate operation ticket instruction; continue to execute step 409.

[0130] Step 409, the main station generates a transmission exit instruction for the current wheel cutting object according to the current wheel cutting interval sequence number, and sends the transmission exit instruction to the stabilization control device, so that the stabilization control device executes the transmission exit based on the transmission exit instruction; continue to execute step 4010.

[0131] Step 4010, the main station receives the message information during the transmission period forwarded by the OCS automation master station, and determines whether the current wheel-cutting object meets the stable control disconnection criterion based on the message information, that is, whether the wheel-cutting object switch is disconnected; if so, jump to step 4011; if not, record the abnormal transmission load interval and jump to step 4013.

[0132] Step 4011, the main station records the successful transmission load interval, generates a remote control closing operation ticket execution instruction, and sends the remote control closing operation ticket execution instruction to the DICP master station, so that the DICP master station executes the shift object operation ticket according to the remote control closing operation ticket execution instruction, and controls the OCS automation master station to remotely close the current shift object; continue to execute step 4012.

[0133] Step 4012, determine whether the current wheel-cutting object is successfully closed, that is, whether the wheel-cutting object switch is closed. If so, jump to step 4013; if not, jump to step 4013 after recording the remote control abnormal load interval.

[0134] Step 4013, the wheel cutting interval sequence numbers are superimposed; jump back to step 407.

[0135] Step 4014, the main station summarizes the non-power-off transmission task records; jump to step 4015.

[0136] Step 4015, end the remote non-stop power transmission process of the stabilization control device.
