In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0049] Terminology explanation:

[0050] The CMS protocol is the standard language for internal communication in smart substations. It is responsible for coordinating the information transmission and processing of various devices in the substation and can ensure the accuracy and real-time nature of the data.

[0051] Figure 1 FIG. 1 is a schematic diagram of a structure of a CMS protocol-based intelligent substation simulation debugging system according to an embodiment of the present invention. Figure 1 The CMS protocol-based intelligent substation simulation debugging system in the present embodiment shown may include: a CMS client simulation system, a CMS server simulation system, and a CMS message capture and analysis tool;

[0052] The CMS client simulation system is used to retrieve the corresponding parsed substation configuration description language (SCL) model file for parameter configuration (including SCL file, IP address, MAC address, etc.), simulate the client device to implement command request operation, message sending and receiving operation and command and message processing operation; wherein, the client device is a master station or a gateway machine;

[0053] The CMS server simulation system is used to simulate the secondary system device and communicate with the simulated client device to implement the change data sending and message sending operations;

[0054] The CMS message capture and analysis tool captures and analyzes messages sent and received by the CMS client simulation system and the CMS server simulation system, and modifies the configuration information of the CMS client simulation system and / or the CMS server simulation system according to the analysis results.

[0055] This embodiment uses a simulation client to view the four remote information, set values, device information, etc., and can issue telesignaling and telemetry data, remote control, set value commands, etc.; the simulation server is used to send protection, measurement and control, power supply and other collected information to the main station or real-time gateway, and respond to the commands issued by the main station or real-time gateway, providing flexible simulation and debugging means for smart substation gateways, backgrounds, measurement and control, protection, power supplies and other products, thereby improving the debugging efficiency of autonomous and controllable CMS protocol communications.

[0056] In some specific implementations, the CMS client simulation system obtains and analyzes the substation configuration description language (SCL) model file from the local, such as Figure 2 shown.

[0057] The parsed substation configuration description language (SCL) model file includes telesignaling, telemetering information, data set information, report control block information, remote control related information, set value control block information, set value list and log control block information.

[0058] In some other optional implementations, the CMS client simulation system dynamically obtains and parses the substation configuration description language (SCL) model file from the CMS server simulation system, such as Figure 3 shown.

[0059] The process of the CMS client simulation system dynamically obtaining and parsing the substation configuration description language (SCL) model file from the CMS server simulation system includes:

[0060] The CMS client simulation system is associated with the CMS server simulation system to determine whether the two are connected. If so, the server directory, logical device target, logical node directory, data directory, data value and all control block values ​​are read in sequence.

[0061] In some specific implementations, the CMS client simulation system includes a command request unit, a service logic unit, and a message manufacturing center;

[0062] The command request unit is used to issue various command requests; wherein the command requests include read and write commands, model commands, control commands, set value commands and exception request commands.

[0063] The service logic unit is used for logic processing and abnormal judgment of each server, including processing of each command request and receiving and decoding of messages.

[0064] The message manufacturing center is used to encode and send each command.

[0065] Through the simulation service communication, information is exchanged with protection, measurement and control devices. The simulation process of the CMS client simulation system, such as Figure 4 As shown. Based on CMS client simulation communication abnormality debugging, when deploying interval layer equipment in the intelligent station, the CMS client simulation system can be used to debug it. When the monitoring background, real-time gateway machine or intelligent anti-error host machine and the secondary equipment have communication abnormalities, and when the real-time gateway machine and the dispatching master station have communication abnormalities, abnormality investigation and debugging can be performed.

[0066] CMS client simulation debugging architecture Figure 5As shown. When it is used as CMS client 1, the communication with the real-time gateway is normal, indicating that the abnormality occurs on the link of the master station communication, otherwise it indicates that the abnormality occurs on the real-time gateway side. When it is used as CMS client 2, the communication with the secondary equipment protection and multi-function measurement and control device is normal, and the abnormality occurs on the real-time gateway side, otherwise it occurs on the secondary equipment side.

[0067] The CMS client simulation system can be used for abnormal analysis. When it is inconvenient to view relevant data, you can use the simulation client to view data, call four remote information, set value information, and call files for analysis. The CMS client simulation system can also realize remote control, set value setting, remote access and other operations.

[0068] In one or more embodiments, Figure 6 As shown, the CMS server simulation system includes an auxiliary center, an SCD analysis module, a data simulation center, a simulation logic center, a message processing center and a network communication center;

[0069] The auxiliary center is used to configure information; for example, configure the size of the server APDU and ASDU, configure the allowed connection whitelist, etc.

[0070] The SCD parsing module is used to parse the SCD; the parsing information type is the same as the simulation client, but the difference is that the constructed structure is different. Parsing the SCD is the basis of the service.

[0071] The data simulation center is used to simulate data according to the parsed SCD; the data simulation can be performed through an interface or a script.

[0072] The simulation logic center is used to process and analyze messages for each service;

[0073] The message processing center is used to process received messages and organize messages according to services;

[0074] The network communication center is used to parse and send the protocol.

[0075] The CMS server simulation system simulation device can be used with the main and auxiliary integrated machines, real-time gateway machines, and intelligent anti-error host machines for joint debugging. The master station sends four remote control, fixed value and other commands. After the CMS server simulation system receives the command sent by the master station, it organizes the corresponding message to complete the correct response. The debugging architecture of the CMS server simulation system is as follows Figure 7 shown.

[0076] In one or more embodiments, the intelligent substation simulation debugging system based on the CMS protocol is constructed based on the change of the data source and the reception and transmission of the simulation message. The intelligent substation simulation debugging system based on the CMS protocol also includes a unified security management module, which is used to manage user information, permissions and logs.

[0077] In one or more embodiments, a CMS protocol-based intelligent substation simulation debugging method is also provided, including:

[0078] Step 1: Use the CMS client simulation system to retrieve the corresponding substation configuration description language (SCL) model file for parameter configuration and simulate the client device to implement command request operations, message sending and receiving operations, and command and message processing operations; wherein the client device is a master station or a gateway machine;

[0079] Step 2: Use the CMS server simulation system to simulate the secondary system device and communicate with the simulated client device to implement the change data sending and message sending operations;

[0080] Step 3: Capture and analyze the messages sent and received by the CMS client simulation system and the CMS server simulation system, and modify the configuration information of the CMS client simulation system and / or the CMS server simulation system according to the analysis results.

[0081] This embodiment provides CMS abnormality detection means for the main and auxiliary integrated machines, real-time gateway machines, and intelligent anti-error host deployment of smart substations, and provides them with flexible debugging means such as simulation data changes and abnormal analysis; through the CMS debugging system, the four remote controls and fixed value information can be viewed, and the master station or real-time gateway machine can be simulated to send commands, etc., which improves the debugging efficiency of smart substation deployment and ensures the normal operation of smart substations.
