Description

Technical Field

[0001] This application relates to the field of substation monitoring technology, and more specifically, to a method and apparatus for updating a forwarding point table and a non-volatile storage medium. Background Technology

[0002] The substation remote control unit (RCU) is responsible for transmitting information from within the substation to the master station of the dispatch automation system. Routine changes to the power grid structure, new line commissioning, and integrated automation upgrades all require updating the RCU's forwarding point table. After the forwarding point table is updated, maintenance personnel at both the substation and master station ends must conduct debugging and verification before the update work is complete.

[0003] However, due to the large amount of data in the forwarding point table of the remote control unit (RCU), with over a thousand remote signaling points in a single 110kV substation, verifying all forwarding points for every change to the forwarding point table would be extremely labor-intensive. Furthermore, since all equipment except for the modified bays is already energized, it is impossible to manually trigger signals for verification with the master station. Therefore, after each change to the forwarding point table of the RCU, only the modified forwarding points are verified. If the manufacturer mistakenly modifies the forwarding point table during commissioning, the point numbers of signals that have already been verified may be changed or deleted, creating safety hazards and preventing important signals from being transmitted to the dispatcher's interface, thus posing a risk to the power grid.

[0004] The verification of the substation remote control relay point table is completed through joint debugging by both the substation and the master station. When the equipment is de-energized, the substation manually triggers a signal. If the master station receives a correct signal, the debugging is successful. However, this method only verifies the correctness of the signals in the de-energized part. Although other signals in the relay point table have been verified before commissioning, it is possible that after a period of time, someone may accidentally change the relay point table for other reasons. Such safety hazards are difficult to detect. If the change is to telemetry, the anomaly can be easily detected through the telemetry over-limit alarm. However, if the change is to remote signaling, since remote signaling does not send signals under normal circumstances and is only triggered when an anomaly occurs in the substation, there may be signal omissions or mis-sent signals, affecting the dispatcher's judgment and increasing the risk to the power grid.

[0005] In summary, after modifying the forwarding point table of the remote control unit, only the modified parts were verified, which led to potential safety hazards in the substation management process.

[0006] There is currently no effective solution to the above problems. Summary of the Invention

[0007] This application provides a method and apparatus for updating a forwarding point table, as well as a non-volatile storage medium, to at least solve the technical problem of potential safety hazards in substation management caused by only verifying the modified parts after modifying the forwarding point table of the remote motor in the substation.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] To better understand the embodiments of this application, the technical terms involved in the embodiments of this application are explained below:

[0028] Remote control (RCD) devices are used for remote control and monitoring in power systems. Their main functions include remote control, telemetry, and remote signaling of power equipment. Remote control (YK) is a technology that uses radio waves or communication lines to remotely operate and manage power equipment. It is mainly used in substations for operation ticket management, equipment startup, and equipment commissioning. For example, remote control technology can be used to remotely operate circuit breakers, reducing the need for manual on-site operation and improving operational safety and efficiency. Telemetry (YC) uses sensors and communication technology to remotely measure the operating parameters of power equipment, such as voltage, current, and power. It is mainly used in substations and distribution rooms to measure parameters such as voltage, current, and power. For example, wireless temperature sensors can be used to monitor the environment and equipment status of high and low voltage distribution cabinets in real time, ensuring the safe operation of power equipment. Telesignaling (YX) uses sensors to remotely monitor the operating status of power equipment, mainly used for transmitting switch status and alarm information. It is used to monitor the status of protection devices, voltage regulators, current transformers, and other equipment. For example, it collects and transmits various protection and switching information to determine whether the equipment is operating normally or has malfunctioned. Remote adjustment (T&T) uses radio waves to remotely regulate power equipment, primarily for adjusting operating parameters such as voltage and current. It is mainly used for voltage and current regulation in substations. For example, remote adjustment can remotely set the tap position of a transformer and adjust the output power of a generator.

[0029] The forwarding point table for remote actuators in a substation is mainly used to define and record data point information that remote actuators (installed in the substation) need to forward to the dispatch master station. This information includes, but is not limited to, telemetry (such as voltage, current, power, etc.), remote signaling (such as switch position, protection action signals, etc.), remote control (such as circuit breaker opening and closing control), and remote adjustment (such as transformer tap adjustment). The accuracy and completeness of the remote actuator forwarding table are crucial for the safe, stable, and efficient operation of the power system. The main functions of the remote actuator forwarding table are as follows: 1. Data forwarding: The remote actuator reads real-time data from various devices in the substation and forwards this data to the dispatch master station according to the configuration in the forwarding table. The dispatch master station can monitor the operating status of the power grid in real time by receiving this data. 2. Control command execution: In addition to forwarding data, the remote actuator also needs to find the corresponding control point in the forwarding table according to the control commands (such as circuit breaker opening and closing control) issued by the dispatch master station and execute the corresponding control operations. 3. Security verification: During the data forwarding and control command execution process, the remote actuator forwarding table also plays a certain security verification role. By comparing the data in the forwarding table with the actual situation, the accuracy of the data and the correctness of the control instructions can be ensured, preventing erroneous operations.

[0030] Alarm direct transmission: This refers to the process of using a single event or comprehensive analysis result from the substation monitoring system as the information source, processing it in a standardized manner to generate standard alarm clauses, and then transmitting them directly to the dispatch master station and equipment maintenance station in text format via the alarm direct transmission system.

[0031] In related technologies, it is impossible to periodically verify whether the forwarding point table of the remote actuators in the substation is consistent with the forwarding point table of the control master station, which poses a significant safety hazard. To solve this problem, this application provides a relevant solution, which is described in detail below.

[0032] According to an embodiment of this application, a method embodiment for updating a forwarding point table 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.

[0033] Figure 1 This is a flowchart of a forwarding point table update method according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0034] Step S102: Obtain the alarm direct transmission information sent by the substation monitoring system to the control master station. The alarm direct transmission information includes at least the identification information of the target equipment in the substation that caused the alarm.

[0035] The control station is the command center for power grid operation, centrally controlling substations. It sends control commands to substations via a remote communication system, such as the opening and closing of circuit breakers and the adjustment of transformer taps. Substations then execute the corresponding operations according to the commands from the control station, achieving real-time control of the power grid. Various equipment in the substations, such as instrument transformers and monitoring devices, collect power grid operating data, including telemetry information such as voltage, current, and power, as well as remote signaling information such as equipment status and switch positions. This information is uploaded to the control station via the remote communication system, enabling control personnel to understand the real-time operating status of the power grid. Simultaneously, substations also receive parameter settings and control strategies from the control station, achieving two-way information flow.

[0036] When a fault occurs in primary equipment (such as transformers, circuit breakers, disconnectors, etc.) or secondary equipment (such as protection devices, monitoring and control devices, etc.) within a substation, the substation monitoring system will immediately issue a fault alarm message. When the operating parameters of equipment in the substation exceed the normal range or abnormal conditions occur, such as excessively high or low voltage, current overload, or abnormal frequency, the monitoring system will issue an abnormal operation alarm message. These fault alarm messages and abnormal operation alarm messages constitute the direct alarm transmission information. For example, the specific format of the direct alarm transmission information is: alarm level, alarm time, substation name, equipment name, alarm content, and alarm reason. Each field is separated by a single space, and an empty field is indicated by a quotation mark (""). Alarm levels 1 represent an accident, 2 an abnormality, 3 an over-limit, 4 a displacement, and 5 a notification.

[0037] The alarm message transmitted directly is as follows: "#1 main transformer high voltage 101 switch main protection device activated", that is, the high voltage side of the main transformer numbered 1 triggered the main protection device, causing the 101 switch to trip.

[0038] Step S104: Obtain the remote control message sent by the remote control unit received by the control master station. The remote control message includes at least the identification information of the equipment in the substation.

[0039] The remote control message sent by the remote control unit to the control master station includes at least: remote signaling information, which includes: equipment status signals, such as the opening and closing status of switches, the action signals of protection devices, and the tap position of transformers.

[0040] Remote signaling information, for example: "#2 main transformer low voltage 102 switch main protection device activated", that is, the low voltage side of the main transformer numbered 2 triggered the main protection device, causing the 102 switch to trip.

[0041] Step S106: Based on the alarm direct transmission information and remote control message received by the control master station within a preset time period, determine whether the forwarding point of the control master station is consistent with the forwarding point of the substation.

[0042] Step S108: If the forwarding point of the control master station is inconsistent with the forwarding point of the substation, update the forwarding point table of the control master station or the forwarding point table of the substation.

[0043] For example, if a switch protection action occurs in a substation, the following signal is generated: "#1 Main Transformer High Voltage 101 Switch Main Protection Action". In the remote control message, this signal will be accompanied by a Sequence of Events (SOE) timestamp. Simultaneously, the alarm direct transmission channel should also simultaneously transmit the same signal with the same SOE timestamp. If the transmitted signal is received from the remote control message, a waiting period begins. If no signal with the same time point appears within the specified time range in the alarm direct transmission message, it is determined that the alarm direct transmission channel configuration is incorrect, and the alarm direct transmission channel configuration error information, along with the device name in the signal, is sent to the substation monitoring system. If the transmitted signal is received from the alarm direct transmission channel, a waiting period begins. If no signal with the same time point appears within the specified time range in the remote control message, it is determined that the remote control transmission configuration is incorrect, and the transmission configuration error information, along with the device name in the signal, is sent to the substation monitoring system.

[0044] Based on the above steps, the system acquires alarm direct transmission information received by the control master station from the substation monitoring system. This alarm direct transmission information includes at least the identification information of the target equipment in the substation that triggered the alarm. It also acquires remote control messages received by the control master station from the remote control unit. These remote control messages include at least the identification information of the equipment in the substation. Based on the alarm direct transmission information and remote control messages received by the control master station within a preset time period, it determines whether the forwarding point of the control master station is consistent with the forwarding point of the substation. If the forwarding point of the control master station is inconsistent with the forwarding point of the substation, it updates the forwarding point table of either the control master station or the substation. This method achieves the purpose of online verification and updating of the modified forwarding point table, thereby realizing the technical effect of eliminating potential safety hazards in substation management.

[0045] The following are Figure 1 The steps shown are illustrated and explained by way of example.

[0046] According to some optional embodiments of this application, determining whether the forwarding point of the control master station is consistent with the forwarding point of the substation based on the alarm direct transmission information and remote control message received by the control master station within a preset time period can be achieved by the following method: detecting whether there is a first signal and a first time mark corresponding to the first signal in the remote control message, wherein the first signal includes at least: the switching operation status of the equipment; if the first signal and the first time mark appear in the remote control message, setting the time when the first signal appears in the remote control message to zero time and starting the timing operation; if no alarm direct transmission information including the first signal and the first time mark is received within a first preset time period from the zero time, determining that the forwarding point of the control master station is inconsistent with the forwarding point of the substation.

[0047] For example, the remote control (RTC) message is checked for the presence of equipment status signals (first signals), such as the opening / closing status of switches, the action signals of protection devices, the tap position of transformers, etc., as well as the timestamp corresponding to the first signal. Assuming that at 8:00:00, the RTC message contains the signal "#2 Main Transformer Low Voltage 102 Switch Main Protection Action" along with the corresponding timestamp 7:58:23, 8:00:00 is set to zero, and the timing operation begins. If, within 2 seconds of zero, no alarm transmission information including "#2 Main Transformer Low Voltage 102 Switch Main Protection Action" and the timestamp 7:58:23 is received, it can be determined that the forwarding point of the control master station is inconsistent with the forwarding point of the substation.

[0048] On the other hand, based on the alarm direct transmission information and remote control messages received by the control master station within a preset time period, it can be determined whether the forwarding point of the control master station is consistent with the forwarding point of the substation. This can be achieved by the following method: detecting whether there is a second signal and a second time marker corresponding to the second signal in the alarm direct transmission information, wherein the second signal includes at least: the switching operation status of the equipment; if the second signal and the second time marker appear in the alarm direct transmission information, the time when the second signal appears in the alarm direct transmission information is set to zero and the timing operation starts; if no remote control message including the second signal and the second time marker is received within the second preset time period from the zero time, it is determined that the forwarding point of the control master station is inconsistent with the forwarding point of the substation.

[0049] For example, the system checks whether the alarm transmission information contains a device status signal (second signal), such as the opening / closing status of a switch, the action signal of a protection device, the tap position of a transformer, etc., as well as the timestamp corresponding to this second signal. Assuming that at 9:00:00, the remote control message contains the signal "#1 Main Transformer High Voltage 101 Switch Main Protection Action" along with the timestamp 6:58:49, the system sets 9:00:00 to zero and starts timing. If, within 2 seconds of zero, no remote control message containing "#1 Main Transformer High Voltage 101 Switch Main Protection Action" and the timestamp 6:58:49 is received, it can be determined that the forwarding point of the control master station is inconsistent with the forwarding point of the substation.

[0050] Furthermore, after determining that the forwarding point of the control master station and the forwarding point of the substation are inconsistent, the following steps can be performed: A first message is sent to the substation monitoring system, wherein the first message includes at least: the identification information of the equipment in the first signal and the alarm direct transmission channel configuration error information. A second message is sent to the substation monitoring system, wherein the second message includes at least: the identification information of the equipment in the second signal and the transmission configuration error information.

[0051] In other words, if an uplink signal is received in a remote control message, the system starts waiting. If no signal at the same time point appears within the specified time range in the alarm direct transmission message, it is determined that the alarm direct transmission channel is misconfigured, and the alarm direct transmission channel configuration error information and the device name in the signal are sent to the substation monitoring system.

[0052] If an alarm signal is received from the direct alarm transmission channel, the system will wait. If no signal at the same time point appears in the remote control message within the specified time range, it will be determined that the remote control transmission configuration is incorrect, and the transmission configuration error information and the device name in the signal will be sent to the substation monitoring system.

[0053] As some optional embodiments of this application, when the forwarding point of the control master station and the forwarding point of the substation are inconsistent, updating the forwarding point table of the control master station or the forwarding point table of the substation can be achieved by the following methods:

[0054] If the number of forwarding points at the control master station is less than the number of forwarding points at the substation, obtain the forwarding point table of the control master station and the forwarding point table of the substation; determine whether the forwarding point table of the control master station and the forwarding point table of the substation include the preset signal corresponding to the target equipment, wherein the preset signal includes at least: the three-phase switch of the target equipment undergoes a three-phase inconsistent operation; if the preset signal is not included in the forwarding point table of the control master station, but is included in the forwarding point table of the substation, add the target equipment to the forwarding point table of the control master station.

[0055] In other words, if the number of forwarding points at the control master station is less than the number of forwarding points at the substation, it is necessary to export the substation forwarding point table to verify whether there are any important signals that need to be collected according to the specifications, and whether there are any signals that the control master station has missed collecting, such as inconsistent operation of three-phase switches. If the master station has not collected these important signals, but the substation has forwarded them, the master station's database needs to be modified immediately so that the signal can be sent to the dispatcher's interface normally.

[0056] Furthermore, when the forwarding points of the control master station and the forwarding points of the substation are inconsistent, updating the forwarding point table of the control master station or the forwarding point table of the substation can be achieved by the following method: if the number of forwarding points of the control master station is greater than the number of forwarding points of the substation, obtain the forwarding point table of the control master station and the forwarding point table of the substation; identify the target forwarding point that differs between the forwarding point table of the control master station and the forwarding point table of the substation, and determine whether the forwarding signal corresponding to the target forwarding point is a preset signal; if the forwarding signal corresponding to the target forwarding point is a preset signal, send a first instruction to the substation monitoring system, wherein the first instruction is used to instruct the data stored in the remote control unit to be reconfigured.

[0057] In other words, if the number of forwarding points at the control master station exceeds the number of forwarding points at the substation, and if this signal is critical, the remote control data needs to be re-downloaded to ensure that the signal can be transmitted normally through the remote control message. It is worth noting that because signals in the alarm direct transmission message do not currently trigger alarms, the remote control message must ensure that critical signals can be transmitted to the dispatcher's interface.

[0058] Preferably, when the forwarding point of the control master station is inconsistent with the forwarding point of the substation, updating the forwarding point table of the control master station or the forwarding point table of the substation can be achieved by the following method: when the point number of the forwarding point of the control master station is inconsistent with the point number of the forwarding point of the substation, receive the updated forwarding point table of the control master station or the updated forwarding point table of the substation.

[0059] Understandably, when the forwarding point number of the control station is inconsistent with the forwarding point number of the substation, the substation maintenance personnel need to enter the station to check the drawings and adjust the forwarding point table of the control station or the forwarding point table of the substation according to the actual situation.

[0060] Figure 2 This is a structural diagram of a forwarding point table updating device according to an embodiment of this application, such as... Figure 2 As shown, the device includes:

[0061] The first acquisition module 20 is used to acquire alarm direct transmission information sent by the substation monitoring system to the control master station. The alarm direct transmission information includes at least the identification information of the target equipment in the substation that caused the alarm.

[0063] The determination module 24 is used to determine whether the forwarding point of the control master station is consistent with the forwarding point of the substation based on the alarm direct transmission information and remote control message received by the control master station within a preset time period.

[0064] Update module 26 is used to update the forwarding point table of the control master station or the forwarding point table of the substation when the forwarding point of the control master station is inconsistent with the forwarding point of the substation.

[0065] Optionally, the determining module 24 is further configured to perform the following steps: detect whether there is a first signal and a first time marker corresponding to the first signal in the remote control message, wherein the first signal includes at least: the switching operation status of the equipment; if the first signal and the first time marker appear in the remote control message, set the time when the first signal appears in the remote control message to zero time and start timing operation; if no alarm direct transmission information including the first signal and the first time marker is received within a first preset time period from the zero time, determine that the forwarding point of the control master station is inconsistent with the forwarding point of the substation.
