Description

Technical Field

[0001] This invention relates to an acceptance verification system and verification method for accessing monitoring information from existing substations to a centralized control station, belonging to the field of power system automation technology. Background Technology

[0002] With the development of business needs of power grid centralized control stations, more and more new centralized control stations are being built. To complete the monitoring of substations within their jurisdiction, the primary task of these stations is to stably, reliably, and efficiently access the main equipment monitoring information of existing substations. The accuracy of the accessed information directly affects the safe operation of the substations. Currently, the reality is that there are a huge number of existing substations. Under the premise of uninterrupted power supply, traditional acceptance methods cannot verify all signals one by one; only spot checks can be performed. This is especially true for remote control signals, where traditional acceptance methods pose significant risks (such as loose connections after disassembling and restoring terminals). Research on automatic verification technology for the access of existing substation monitoring information to centralized control stations has significant practical value. Currently, there is a lack of a fully functional acceptance system and a good verification method to achieve comprehensive verification. There is no complete solution for the access and acceptance of existing substation monitoring information, and the needs of centralized control systems for accessing and accepting existing substation monitoring information cannot be fully met. Summary of the Invention

[0003] Purpose of the invention: This invention provides an acceptance verification system and method for accessing monitoring information of existing substations to a centralized control station, which at least partially solves the problems of the prior art.

[0004] Technical solution: According to a first aspect of the present invention, an acceptance verification system for accessing monitoring information of existing substations to a centralized control station is provided, including a centralized control system, a data communication gateway, a monitoring host, and an automatic acceptance tester;

[0005] The centralized control system is used to perform signal joint debugging with the substations and to verify and accept the correctness of the remote signaling and telemetry configuration according to the acceptance strategy; the centralized control system has the function of batch issuing remote control preset commands, which is used to perform batch remote control acceptance with the substations.

[0006] The remote signaling and telemetry forwarding configuration of the data communication gateway is used as the benchmark data, and the correctness of the remote signaling and telemetry forwarding configuration of its centralized control link is verified by the automatic acceptance tester through comprehensive comparison.

[0007] The remote control configuration of the monitoring host is used as benchmark data, and the correctness of the remote control configuration of the centralized control system and the remote forwarding configuration of the data communication gateway are comprehensively compared and verified by the automatic acceptance tester.

[0008] The automatic acceptance tester simulates multiple protection and control devices based on model files, simulating information input and output based on station control layer communication. Following the acceptance configuration strategy, it makes station control layer communication messages customizable and interactive behavior controllable. Based on the configuration, it simulates and schedules the master station and centralized control master station, receives data forwarded by the data communication gateway, records the multi-channel forwarding remote signaling and telemetry data of the data communication gateway, and automatically compares the consistency to verify the correctness of the remote signaling and telemetry centralized control link forwarding table of the data communication gateway. It records the preset remote control objects of the centralized control system, the preset remote control objects of the data communication gateway, and the preset remote control objects of the monitoring host, performs a comprehensive comparison, and verifies the correctness of the remote control configuration of the centralized control system and the remote control forwarding table of the data communication gateway. It batch triggers changed data, driving the data communication gateway to forward data to the centralized control system, which then verifies the correctness of the remote signaling and telemetry configuration on the centralized control system side.

[0009] According to a second aspect of the present invention, an acceptance verification method for accessing monitoring information of existing substations to a centralized control station is provided, comprising the following steps:

[0010] The automatic acceptance tester simulates multiple protection and control devices based on model files, and simulates information input and output based on station control layer communication. According to the acceptance configuration strategy, the station control layer communication messages are customizable and the interactive behavior is controllable. According to the configuration, the simulation schedules the master station and the centralized control master station, and receives data communication gateways to forward remote signaling and telemetry data.

[0011] The centralized control system imports the centralized control information point table and performs consistency verification on the configuration information of the front-end database of the simulated scheduling master station and the centralized control master station;

[0012] The automatic acceptance tester and the data communication gateway form a closed-loop connection, so that the automatic acceptance tester serves as both the input data source and the data forwarding receiver of the data communication gateway. The automatic acceptance tester triggers corresponding signals based on the remote signaling configuration and telemetry configuration in the data communication gateway's scheduling link forwarding table file, and performs consistency verification on the remote signaling forwarding values ​​of the centralized control link and the scheduling link of the data communication gateway, as well as on the telemetry forwarding values ​​of the centralized control link and the scheduling link of the data communication gateway.

[0013] The automatic acceptance tester is used only as a data input for the data communication gateway. The data communication gateway forwards data to the centralized control system. The automatic acceptance tester triggers corresponding signals based on the remote signaling and telemetry configurations in the data communication gateway's scheduling link forwarding table file to verify the remote signaling data on the master station side and the telemetry data on the master station side.

[0014] The monitoring host and the automatic acceptance tester are connected. The protection and control equipment simulated by the automatic acceptance tester communicates and interacts with the monitoring host. The centralized control system issues remote control preset commands in batches according to the remote control point number sequence of the centralized control information point table. The data communication gateway forwards the commands to the control equipment simulated by the automatic acceptance tester to verify the correctness of the remote control.

[0015] Beneficial Effects: This invention utilizes an automatic acceptance tester to automatically perform dynamic consistency comparison of the remote signaling and telemetry data of the centralized control link and the dispatch link of the data communication gateway, and automatically generates an acceptance report based on the comparison results. This efficiently, reliably, and comprehensively verifies the correctness of the centralized control link configuration of the data communication gateway. Through automatic signal triggering of the automatic acceptance tester and joint testing with the automatic acceptance module on the centralized control system side, the correctness of the remote signaling and telemetry on the centralized control system side is verified. By having the centralized control system issue batch preset commands to remote control signals, the automatic acceptance tester combines the remote control data from the centralized control system, the remote control data from the data communication gateway, and the remote control data from the monitoring host to automatically verify the correctness of the remote control configuration on the centralized control system side and the remote control configuration of the centralized control link of the data communication gateway. The automatic generation of a test report based on the comparison results enables the verification of the correctness of accessing existing substation monitoring information to the centralized control system. This solves the problems of inefficiency, incompleteness, and insecurity of traditional acceptance methods for accessing existing substation monitoring information to the centralized control system, meeting the requirements for efficient, comprehensive, and secure acceptance of accessing existing substation monitoring information to the centralized control system.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1As shown, an automatic verification system for the acceptance of monitoring information access to a centralized control station in an existing substation includes a centralized control system, a data communication gateway, a monitoring host, and an automatic acceptance tester. The centralized control system and the data communication gateway are connected during the joint commissioning of the master and substations. The data communication gateway is connected to the automatic acceptance tester, and the monitoring host is connected to the automatic acceptance tester during remote control verification. The centralized control system is mainly used to collect and process remote signaling, telemetry, and remote control information transmitted from the substations, and to perform centralized monitoring and alarms, while also issuing remote control commands. The centralized control system is the object being accepted, and the correctness of its remote signaling, telemetry, and remote control configuration is one of the tasks of the acceptance verification. The data communication gateway is also the object being accepted, and the correctness of its centralized control link's remote signaling, telemetry, and remote control forwarding configuration is one of the tasks of the acceptance verification. The centralized control link of the data communication gateway refers to the centralized control link from the substation equipment through the gateway to the centralized control master station. The general process is that the status information and change information of the substation equipment are transmitted to the gateway, and the gateway forwards the received information to the centralized control master station.

[0022] The centralized control system has an automatic acceptance module for signal integration with substations. Based on the acceptance strategy, it can verify the correctness of remote signaling and telemetry configurations. The centralized control system also has a batch remote control preset command issuance function for batch remote control acceptance with substations. The master station refers to the dispatch master station or centralized control master station, and the substation is a specific substation.

[0023] The remote signaling and telemetry forwarding configuration of the data communication gateway is used as the benchmark data. The correctness of the remote signaling and telemetry forwarding configuration of the centralized control link is verified by the automatic acceptance tester. The data communication gateway is also referred to as the gateway in the following text. Its scheduling link refers to the scheduling link from the equipment in the station through the gateway to the scheduling master station. The general process is that the status information and change information of the equipment in the station are transmitted to the gateway, and the gateway forwards the received information to the scheduling master station.

[0024] The monitoring host remotely controls the switches and disconnectors within the station, controlling their opening and closing. Its remote control configuration serves as benchmark data, which is comprehensively compared and verified by an automatic acceptance tester to confirm the correctness of the remote control configuration of the centralized control system and the remote control forwarding configuration of the data communication gateway. The monitoring host does not require configuration, as the relevant configuration has been completed and verified in practice. It only requires operation, which involves user selection and password input.

[0025] The automatic acceptance tester can simulate multiple protection and control devices based on model files, completely simulating information input and output based on station control layer communication in terms of information interaction. According to the acceptance configuration strategy, station control layer communication messages are customizable, and interactive behavior is controllable. It can simulate the scheduling master station and centralized control master station according to the configuration, receive data forwarded by the data communication gateway, record the multi-channel forwarded remote signaling and telemetry data of the data communication gateway, and automatically compare consistency to verify the correctness of the remote signaling and telemetry centralized control link forwarding table of the data communication gateway; it records the preset remote control objects of the centralized control system, the preset remote control objects of the data communication gateway, and the preset remote control objects of the monitoring host, performs comprehensive comparison, and verifies the correctness of the remote control configuration of the centralized control system and the remote control forwarding table of the data communication gateway; it can batch trigger changed data, driving the data communication gateway to forward data to the centralized control system, where the automatic acceptance module of the centralized control system verifies the correctness of the remote signaling and telemetry configuration on the centralized control system side.

[0026] The automated acceptance testing process is divided into two parts: in-station acceptance and master-slave station acceptance. During in-station acceptance, the automated testing instrument simulates the master station; the actual master station does not need to participate. Otherwise, it would increase the workload of coordination and communication, affecting acceptance efficiency. This is because the equipment within a substation that is already in operation cannot be operated arbitrarily; otherwise, it may trigger accidents and alarms, posing significant safety hazards. Operation would require applying for a complete station power outage or shutdown of specific equipment, which is not conducive to efficient acceptance testing.

[0027] In this embodiment of the invention, the automatic acceptance tester simulates the communication behavior of substation bay-level equipment based on substation bay-level equipment model files, and the interaction behavior is controllable. For example, the automatic acceptance tester reads the SCD file based on the IEC61850 substation to complete the bay-level equipment simulation, and completes communication interaction with the data communication gateway and monitoring host through the IEC61850 communication protocol; it also reads the model file based on the monitoring manufacturer's proprietary communication protocol (such as Network 103) to complete the bay-level equipment simulation, and completes communication interaction with the data communication gateway and monitoring host through a special communication protocol (such as Network 103).

[0028] In this embodiment of the invention, the centralized control system integrates an automatic acceptance function module as an automatic acceptance tool on the master station side. This module includes automatic verification functions for remote signaling and telemetry, and batch triggering functions for preset remote control commands. Specifically, it includes: a centralized control information table verification unit to verify the consistency between the information in the master station's front-end database and the centralized control point table; a remote signaling and telemetry data verification unit to verify the correctness of the master station's front-end remote signaling and telemetry data; and a batch triggering unit for preset remote control commands to enable the master station to issue remote control commands in batches according to the remote control information table order, and to jointly verify the correctness of the remote control configuration with the substations. The automatic verification report for remote signaling and telemetry from the centralized control side automatic acceptance function module includes point number, description, set value, acceptance value, acceptance time, and acceptance conclusion; the automatic verification report for remote control includes point number, description, and preset time.

[0029] Centralized control information table verification: Verify whether the information in the centralized control master station database is consistent with the acceptance information point table, that is, whether the database information maintained by the centralized control master station is consistent with the point table. The meaning of this project is to check whether the master station database is configured according to the point table and verify the correctness of the point table parameter maintenance.

[0030] Remote signaling and telemetry data verification: Verify whether the remote signaling configuration of the database of the centralized control master station is consistent with that of the station-end gateway database, including naming rules, point number arrangement order, coefficient size, polarity inversion, etc. The meaning of this item is to verify the consistency of information configuration between the centralized control master station and the substation.

[0031] Remote control verification: Verify the switches and disconnectors controlled by the centralized control master station at the substation end, including naming rules, remote control point number sequence, control target, etc. The meaning of this item is to verify the correctness of the centralized control master station in remotely controlling the switches and disconnectors within the station.

[0032] The automatic acceptance tester, serving as an automatic acceptance tool for substation monitoring information, specifically includes: an automatic verification module for the correctness of telemetry data in the centralized control link of the data communication gateway, which automatically compares the consistency of telemetry data in the centralized control link and the dispatch link, and completes the configuration verification of newly added centralized control link telemetry data in the gateway; an automatic verification module for the correctness of telemetry data in the centralized control link of the data communication gateway, which automatically compares the consistency of telemetry data in the centralized control link and the dispatch link, and completes the configuration verification of newly added telemetry data in the centralized control link of the data communication gateway; and an automatic verification module for the correctness of remote control data in the centralized control link of the data communication gateway, which comprehensively compares the consistency of remote control data in the centralized control link and the remote control data of the monitoring host, and completes the configuration verification of newly added remote control data in the centralized control link of the gateway. The automatic verification report for telemetry and telemetry data in the automatic acceptance tester includes the point number, description, trigger value, dispatch link forwarding value, centralized control link forwarding value, verification time, and consistency conclusion; the automatic verification report for remote control data includes the point number, description, remote control object of the data communication gateway, remote control object of the monitoring host, verification time, and consistency conclusion.

[0033] The automatic acceptance tester needs to verify the correctness of the newly added centralized control link configuration on the gateway machine at the station end.

[0034] The remote signaling and telemetry signal dispatching master station link has been verified in practice and is correct. The configuration and verification of the newly added centralized control link are completed based on the dispatching master station link.

[0035] The remote control configuration of the station-side monitoring host has been verified in practice and is correct. Based on the remote control of the monitoring host, the remote control verification of the newly added centralized control link is completed.

[0036] The verification method for integrating the monitoring information of existing substations into the automatic verification system for acceptance testing of the centralized control station involves the following steps:

[0037] Step 1: The automatic acceptance tester prepares and configures the data, and the centralized control system verifies the consistency of the configuration information.

[0038] The automatic acceptance tester imports the centralized control information point table, substation configuration file, data communication gateway scheduling link forwarding table file, and configures the scheduling link master station IP and centralized control link master station IP. The substation configuration file is an SCD file for smart substations and a monitoring manufacturer model configuration file for conventional substations. The scheduling link forwarding table file is an RCD file for smart substations and a monitoring manufacturer forwarding table file for conventional substations.

[0039] The automatic acceptance tester simulates all bay-level equipment in the substation based on the substation configuration file.

[0040] The automatic acceptance tester simulates the scheduling master station front-end and the centralized control master station front-end based on the configured IP address information. The simulated front-end receives information sent to the master station by the gateway, thus completing the master station's monitoring function at the station end. The station information sent by the gateway is sent to different places based on different IP addresses. The IP addresses have been configured on the gateway. After the link is normal, the system can monitor the information sent to the master station by the gateway, receive data communication data, and forward remote signaling and telemetry data.

[0041] The automatic acceptance module of the centralized control system imports the centralized control information point table and performs consistency verification with the configuration information in the front-end database;

[0042] Reference Figure 2 The automatic acceptance tester and the data communication gateway form a closed-loop connection, meaning that the automatic acceptance tester serves as both the source of input data for the data communication gateway and the data forwarding receiver for the data communication gateway.

[0043] Step 2: Verify the remote signaling data of the data communication gateway.

[0044] The automatic acceptance tester triggers a batch of reset signals based on the remote signaling configuration in the data communication gateway's scheduling link forwarding table file, driving the data communication gateway to forward remote signaling signals in a reset state.

[0045] Then, following the remote signaling signal sequence, the signal state changes are triggered sequentially: reset -> action -> reset, driving the data communication gateway to forward the signal. The automatic acceptance tester automatically compares the consistency of the remote signaling forwarding values ​​on the centralized control link and the scheduling link of the data communication gateway, and automatically outputs a conclusion to generate an acceptance report. The consistency of the forwarding values ​​refers to whether the values ​​received by the scheduling link and the centralized control link are the same.

[0046] Step 3: Verify the telemetry data of the data communication gateway.

[0047] The automatic acceptance tester triggers zero-value signals in batches based on the telemetry configuration in the data communication gateway's scheduling link forwarding table file, driving the data communication gateway to forward telemetry signal values ​​of zero.

[0048] Then, following the telemetry signal sequence, unique characteristic values ​​(e.g., point number + fixed offset) are triggered sequentially to drive the data communication gateway to forward the signals. The automatic acceptance tester automatically compares the consistency of the telemetry forwarding values ​​on the centralized control link and the scheduling link of the data communication gateway, and automatically outputs a conclusion to generate an acceptance report. The unique characteristic value is the data change sent by the automatic acceptance tester to the gateway; the point number is the point number in the information point table, which is a unique mapping relationship between the master station and the sub-station; consistency refers to the consistency of the telemetry values ​​forwarded by the gateway to the centralized control link and the scheduling link, that is, automatically comparing whether the telemetry values ​​received by the centralized control link and the scheduling link are the same.

[0049] Steps one, two, and three are completed when the automatic acceptance tester and the data communication gateway form a closed-loop connection.

[0050] Step 4: Verify the remote signaling data on the main station side.

[0051] Reference Figure 3 The automatic acceptance tester serves only as data input for the data communication gateway, which forwards data to the centralized control system. Based on the remote signaling configuration in the data communication gateway's scheduling link forwarding table, the automatic acceptance tester triggers a batch of reset signals, driving the data communication gateway to forward remote signaling signals in a reset state. Then, it triggers signal state changes sequentially according to the remote signaling signal order: reset -> action -> reset, driving the data communication gateway to forward. The automatic acceptance function module of the centralized control system automatically provides the remote signaling acceptance conclusion on the master station side based on whether the received data change pattern is consistent with the acceptance strategy, and automatically generates an acceptance report.

[0052] The acceptance strategy refers to the station sending the action signal first and then the reset signal, while the central control station receives the action signal first and then the reset signal. Following the point number sequence, the automatic acceptance instrument triggers the action signal of one point at a time, followed by the reset signal. The automatic acceptance module of the central control system receives the action signal of that point first, and then the reset signal, and determines that the acceptance is successful; otherwise, the acceptance fails.

[0053] Step 5: Verify the telemetry data from the main station.

[0054] Reference Figure 3The automatic acceptance tester triggers zero-value signals in batches according to the telemetry configuration in the data communication gateway's scheduling link forwarding table file, driving the data communication gateway to forward telemetry signal values ​​of zero. Then, it triggers unique characteristic values ​​(such as point number + fixed offset) in sequence according to the telemetry signal order, driving the data communication gateway to forward. The automatic acceptance function module of the centralized control system automatically gives the telemetry acceptance conclusion of the master station side based on whether the received data value is the set unique characteristic value, and automatically generates an acceptance report.

[0055] Step six: Verify the remote control data of the data communication gateway and the centralized control system.

[0056] Reference Figure 4 During remote control acceptance, the monitoring host and the automatic acceptance tester need to be connected. The protection and control equipment simulated by the automatic acceptance tester interacts with the monitoring host through data communication. Then, the centralized control system issues remote control preset commands in batches according to the remote control point number sequence in the centralized control information table. These commands are then forwarded by the data communication gateway to the control equipment simulated by the automatic acceptance tester. The acceptance personnel initiate preset commands for the remote control objects on the monitoring host according to the order of the remote control objects issued by the centralized control master station. The automatic acceptance tester comprehensively compares the remote control objects in the remote control commands of the centralized control system, the remote control objects in the remote control commands of the data communication gateway, and the remote control objects in the remote control commands of the monitoring host to ensure consistency. It automatically completes the remote control correctness verification and automatically generates an acceptance report.

[0057] During remote acceptance testing, the actual centralized control master station and gateway establish a connection and issue remote control commands. At this time, the automatic acceptance instrument does not need to simulate the connection between the centralized control front-end and the gateway; it only needs to listen in to obtain the remote control point number issued by the centralized control. Figure 4 The image shown is a mirror of the centralized control and remote control data. The remote control object is the simulated testing and control equipment on the automatic acceptance tester.

[0058] The above steps one through six complete the acceptance verification of the access of the monitoring information of the existing substation to the centralized control station. It should be understood that the above description in the order of steps one through six is ​​not a limitation of the present invention. Without departing from the essential purpose and scope, it can be performed in different orders. For example, the order of steps two and three can be adjusted, and the order of steps four, five, and six can be adjusted. Generally, steps four and five are performed in sequence. However, if step six is ​​performed between steps four and five, it will affect the acceptance efficiency.
