Description

Technical Field

[0001] The present application relates to the technical field of substation monitoring, and in particular to a method and device for updating a forwarding point table, and a non-volatile storage medium. Background Art

[0002] The substation remote motor is responsible for sending the station information to the dispatching automation system master station. Daily grid changes, new line investment, equipment comprehensive automatic transformation and other work all require changes to the remote motor's forwarding point table. After the forwarding point table is changed, the operation and maintenance personnel on both the substation and master station sides need to debug and verify before the change is completed.

[0003] However, due to the large amount of data in the forwarding point table of the remote motor, a 110kV substation has more than a thousand telesignal points. If all forwarding points need to be verified for each change in the forwarding point table, the workload is large, and since all equipment except the modified interval is energized, it is impossible to manually trigger the signal to verify with the master station. Therefore, each time the remote motor changes the forwarding point table, only the forwarding points of the modified part are verified. If the manufacturer mistakenly modifies the forwarding point table during the debugging process, the point number of the signal that has been verified will be changed or deleted, causing a safety hazard and resulting in the inability to send important signals to the dispatcher interface, posing a power grid risk.

[0004] The verification of the substation telemotor forwarding point table is completed through the cooperation of the station and the master station. When the equipment is powered off, the station triggers the signal manually, and the master station receives the correct signal, then the debugging is passed, but this practice only verifies whether the power outage signal is correct. Although other signals in the forwarding point table have been verified before commissioning, it is not ruled out that after a period of time, someone misoperates or other reasons cause the forwarding point table to be changed. This kind of safety hazard is difficult to be discovered. If the change is telemetry, it is easy to find the abnormality through the telemetry over-limit alarm, but if the change is telesignal, because the telesignal will not send a signal under normal circumstances, it will only be triggered when an abnormality occurs in the substation. At this time, there will be a phenomenon of missing signals or sending other signals by mistake, which will affect the dispatcher's judgment and increase the risk of the power grid.

[0005] In summary, after modifying the forwarding point table of the remote motor, only the modified part is verified, resulting in safety hazards in the substation management process.

[0006] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0007] The embodiments of the present application provide a method and device for updating a forwarding point table, and a non-volatile storage medium, so as to at least solve the technical problem of potential safety hazards in the substation management process caused by only verifying the modified part after modifying the forwarding point table of the telematic motor in the substation.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0028] Telemotor: It is a device used for remote control and monitoring in power systems. Its main function is to realize remote control, telemetry and telesignaling of power equipment. Remote control (YK) is a technology for remote operation and management of power equipment through radio waves or communication lines. It is mainly used for operation ticket management, equipment startup, equipment commissioning and other tasks in substations. For example, the opening and closing of switches can be remotely operated through remote control technology, reducing the need for manual on-site operation and improving operation safety and efficiency. Telemetry (YC) is the remote measurement of operating parameters of power equipment, such as voltage, current, power, etc., through sensors and communication technology. It is mainly used for the measurement of parameters such as voltage, current, power, etc. in substations and distribution rooms. For example, wireless temperature sensors can be used to monitor the environment of high and low voltage distribution cabinets and the status of power equipment in real time to ensure the safe operation of power equipment. Telesignaling (YX) is the remote monitoring of the operating status of power equipment through sensors, mainly used to transmit switch status, alarm direct transmission information, etc. It is used to monitor the status of equipment such as protection devices, voltage regulators, and current transformers. For example, it collects and transmits various protection and switch quantity information to determine whether the equipment is operating normally or has a fault. Teleadjustment (YT) is the remote adjustment of power equipment through radio waves, mainly used to adjust operating parameters such as voltage and current. It is mainly used for voltage regulation and current regulation in substations. For example, through teleadjustment, the tap position of the transformer can be remotely set to adjust the output power of the generator.

[0029] The forwarding point table of the telemotor in the substation: It is mainly used to define and record the data point information that the telemotor (installed in the substation) needs to forward to the dispatching master station. This information includes but is not limited to telemetry (such as voltage, current, power, etc.), telesignaling (such as switch position, protection action signal, etc.), remote control (such as circuit breaker opening and closing control) and remote adjustment (such as transformer tap adjustment). The correctness and integrity of the telemotor forwarding table are crucial to the safe, stable and efficient operation of the power system. The main functions of the telemotor forwarding table are as follows: 1. Data forwarding: The telemotor reads the real-time data of various devices in the substation and forwards these data to the dispatching master station according to the configuration in the forwarding table. The dispatching master station can monitor the operating status of the power grid in real time by receiving these data. 2. Control instruction execution: In addition to forwarding data, the telemotor also needs to find the corresponding control point in the forwarding table according to the control instructions (such as circuit breaker opening and closing control) issued by the dispatching master station, and perform the corresponding control operation. 3. Safety verification: In the process of data forwarding and control instruction execution, the telemotor forwarding table also plays a certain role in safety verification. 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 to prevent the occurrence of misoperation.

[0030] Direct alarm transmission: Using a single event or comprehensive analysis result of the substation monitoring system as the information source, after standardized processing, standard alarm clauses are generated and directly transmitted in text format to the dispatching master station and equipment operation and maintenance station through the direct alarm transmission system.

[0031] In the related art, it is not possible to regularly check whether the forwarding point table of the telemotor in the substation is consistent with the forwarding point table of the control master station, which poses a great safety hazard. In order to solve this problem, the embodiments of the present application provide a related solution, which is described in detail below.

[0032] According to an embodiment of the present application, a method embodiment of a method for updating a forwarding point table is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Figure 1 is a flow chart of a method for updating a forwarding point table according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0034] Step S102, obtaining the alarm direct transmission information sent by the substation monitoring system and received by the control master station, wherein the alarm direct transmission information at least includes: identification information of the target device where the alarm occurs in the substation.

[0035] The control master station is the command center for power grid operation and performs centralized control over substations. It sends control instructions to substations through the telecontrol communication system, such as the opening and closing of circuit breakers and the adjustment of transformer taps. Substations perform corresponding operations according to the instructions of the control master station to achieve real-time control of the power grid. Various types of equipment in the substation, such as transformers, measurement and control devices, etc., collect power grid operation data, including telemetry information such as voltage, current, and power, as well as telesignal information such as equipment status and switch position. This information is uploaded to the control master station through the telecontrol communication system, so that control personnel can understand the operation status of the power grid in real time. At the same time, the substation also receives information such as parameter settings and control strategies issued by the control master station to achieve two-way flow of information.

[0036] When a primary device (such as a transformer, circuit breaker, disconnector, etc.) or secondary device (such as a protection device, measurement and control device, etc.) in a substation fails, the substation monitoring system will immediately issue a fault alarm message. When the operating parameters of the equipment in the substation exceed the normal range or an abnormal situation occurs, such as voltage is too high or too low, current is overloaded, frequency is abnormal, etc., the monitoring system will issue an abnormal operation alarm message. The above-mentioned fault alarm message and abnormal operation alarm message are alarm direct transmission messages. For example, the specific format of the alarm direct transmission message is alarm level, alarm time, substation name, equipment name, alarm content, and alarm reason. Each field is separated by a space, and "" is used to indicate that the field content is empty. Among them, the alarm level 1 is an accident, 2 is an abnormality, 3 is over the limit, 4 is a displacement, and 5 is a notification.

[0037] An example of alarm direct transmission information is: "#1 main transformer high 101 switch main protection action", 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, obtaining a telecontrol message sent by a telemotor and received by the control master station, wherein the telecontrol message at least includes: identification information of equipment in the substation.

[0039] The telecontrol message sent by the telemotor to the control master station includes at least: telesignaling information, which includes: equipment status signals, such as the opening and closing status of switches, action signals of protection devices, gear position of transformers, etc.

[0040] The remote signal information is, for example: "#2 main transformer low voltage 102 switch main protection action", 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, determining whether the forwarding point of the control master station is consistent with the forwarding point of the substation according to the alarm direct transmission information and telecontrol messages received by the control master station within a preset time period.

[0042] Step S108: when 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 the substation, the following signal is generated: "#1 main transformer high 101 switch main protection action". In the telecontrol message, this signal will be sent to the event sequence record (Sequence Of Event, SOE) time stamp. Moreover, the same signal should also be sent to the alarm direct transmission channel at the same time, with the same SOE time stamp. If the sent signal in the telecontrol message is received, the waiting process begins. If the signal at the same time point does not appear in the alarm direct transmission message within the specified time range, it is determined that the alarm direct transmission channel configuration is incorrect, and the alarm direct transmission channel configuration error information and the device name in the signal are sent to the substation monitoring system. If the sent signal in the alarm direct transmission channel is received, the waiting process begins. If the signal at the same time point does not appear in the alarm direct transmission message within the specified time range, it is determined that the remote motor sending configuration is incorrect, and the sending configuration error information and the device name in the signal are sent to the substation monitoring system.

[0044] According to the above steps, the method of obtaining the alarm direct transmission information sent by the substation monitoring system and received by the control master station is adopted, wherein the alarm direct transmission information at least includes: the identification information of the target device in the substation where the alarm occurs; obtaining the telecontrol message sent by the telemotor and received by the control master station, wherein the telecontrol message at least includes: the identification information of the equipment in the substation; 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 telecontrol message received by the control master station within a preset time period; in the case that 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 achieves the purpose of online verification and updating of the modified forwarding point table, thereby realizing the technical effect of eliminating safety hazards in the substation management process.

[0045] The following Figure 1 The steps shown are exemplary and explanatory.

[0046] According to some optional embodiments of the present 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 telecontrol messages received by the control master station within a preset time length 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 telecontrol message, wherein the first signal at least includes: the switch operation status of the equipment; when the first signal and the first time mark appear in the telecontrol message, setting the time when the first signal appears in the telecontrol message to zero time, and starting the timing operation; if the alarm direct transmission information including the first signal and the first time mark is not received within the first preset time length 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, it is detected whether there is a status signal (first signal) of the equipment in the telecontrol message, such as the opening and closing status of the switch, the action signal of the protection device, the gear position of the transformer, etc., and the timestamp corresponding to the first signal. Assuming that at 8:00:00, the "#2 main transformer low 102 switch main protection action" signal and the timestamp 7:58:23 corresponding to the signal appear in the telecontrol message, set the time of 8:00:00 to the zero time, and start the timing operation. If within 2s from the zero time, the alarm direct transmission information including the "#2 main transformer low 102 switch main protection action" and the timestamp of 7:58:23 is not 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, according to the alarm direct transmission information and telecontrol message received by the control master station within the preset time length, determining whether the forwarding point of the control master station is consistent with the forwarding point of the substation can be achieved by the following method: detecting whether there is a second signal and a second time mark corresponding to the second signal in the alarm direct transmission information, wherein the second signal at least includes: the switch operation status of the equipment; when the second signal and the second time mark appear in the alarm direct transmission information, the time when the second signal appears in the alarm direct transmission information is set to zero time, and the timing operation is started; if the telecontrol message including the second signal and the second time mark is not received within the second preset time length 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, it is detected whether there is a status signal (second signal) of the equipment in the alarm direct transmission information, such as the opening and closing status of the switch, the action signal of the protection device, the gear position of the transformer, etc., and the timestamp corresponding to the second signal. Assume that at 9:00:00, the "#1 main transformer high 101 switch main protection action" signal and the timestamp 6:58:49 corresponding to the signal appear in the telecontrol message, set the time of 9:00:00 to the zero time, and start the timing operation. If within 2s from the zero time, no telecontrol message including "#1 main transformer high 101 switch main protection action" and the timestamp of 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 is inconsistent with the forwarding point of the substation, the following steps may be performed: sending a first message to the substation monitoring system, wherein the first message at least includes: the identification information of the device in the first signal and the alarm direct transmission channel configuration error information. Sending a second message to the substation monitoring system, wherein the second message at least includes: the identification information of the device in the second signal and the sending configuration error information.

[0051] That is to say, if an upward signal is received in a telecontrol message, it starts waiting. If the signal at the same time point does not appear in the alarm direct transmission message within the specified time range, it is determined that the alarm direct transmission channel configuration is incorrect, 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 upward signal is received in the alarm direct transmission channel, it starts waiting. If the signal at the same time point does not appear in the telecontrol message within the specified time range, it is determined that the telecontrol sending configuration is incorrect, and the sending configuration error information and the device name in the signal are sent to the substation monitoring system.

[0053] As some optional embodiments of the present application, 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:

[0054] When the number of forwarding points of the control master station is less 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; determine whether the preset signal corresponding to the target device is included in the forwarding point table of the control master station and the forwarding point table of the substation, wherein the preset signal at least includes: the three-phase switch of the target device has a three-phase inconsistent action; if the preset signal is not included in the forwarding point table of the control master station, and the preset signal is included in the forwarding point table of the substation, add the target device to the forwarding point table of the control master station.

[0055] In other words, when the number of forwarding points of the control master station is less than the number of forwarding points of the substation, it is necessary to export the substation forwarding point table to verify whether there are important signals that need to be collected within the specifications, and whether there are any missed signals in the control master station, such as inconsistent operation of the three-phase switch. If these important signals are not collected by the master station but forwarded by the substation, it is necessary to modify the database of the master station immediately so that the signal can be sent to the dispatcher interface normally.

[0056] Furthermore, 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 number of forwarding points of the control master station is greater than the number of forwarding points of the substation, obtaining the forwarding point table of the control master station and the forwarding point table of the substation; determining the target forwarding point where there is a difference between the forwarding point table of the control master station and the forwarding point table of the substation, and determining whether the forwarding signal corresponding to the target forwarding point is a preset signal; when the forwarding signal corresponding to the target forwarding point is a preset signal, sending a first instruction to the substation monitoring system, wherein the first instruction is used to instruct reconfiguration of data stored in the remote motor.

[0057] That is, when the number of forwarding points of the control master station is greater than the number of forwarding points of the substation, if the signal is an important signal, the telecontrol machine data needs to be reinstalled to ensure that the signal can be sent up through the telecontrol message normally. It is worth noting that, because the signal in the alarm direct transmission message is not an alarm, the telecontrol message must ensure that the important signal can be sent to the dispatcher 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, receiving the updated forwarding point table of the control master station or the updated forwarding point table of the substation.

[0059] It is understandable that 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, the substation operation and maintenance personnel are required to enter the station to check the drawings and adjust the forwarding point table of the control master station or the forwarding point table of the substation according to the actual situation.

[0060] Figure 2 is a structural diagram of a device for updating a forwarding point table according to an embodiment of the present application, such as Figure 2 As shown, the device comprises:

[0061] The first acquisition module 20 is used to acquire the alarm direct transmission information sent by the substation monitoring system and received by the control master station, wherein the alarm direct transmission information at least includes: identification information of the target device where the alarm occurs in the substation.

[0062] The second acquisition module 22 is used to acquire the telecontrol message sent by the telemotor and received by the control master station, wherein the telecontrol message at least includes: identification information of the equipment in the substation.

[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 according to the alarm direct transmission information and the telecontrol message received by the control master station within a preset time period.
