Description

Technical Field

[0001] The invention relates to the technical field of substations, and in particular to an automatic calibration system for substation meters. Background Art

[0002] With the increasing popularity of unmanned smart substations, whether the dispatch center can correctly monitor the substation is a prerequisite for the safe and stable operation of the power grid, which requires the substation information stored in the dispatch center to be highly accurate. The point of the smart substation is to check the substation information stored in the dispatch center with the actual substation information to verify the consistency between the two, so as to ensure that the dispatch center can correctly monitor the substation.

[0003] To ensure that the dispatch center can correctly monitor the station, the correctness of the information received by the dispatch center should be ensured. Since the operating status information of IEC60870-5-104 does not contain the specific name of a certain device in the station, but uses the information address to identify the name of a certain station device. The dispatch center stores a storage table containing the names of all substation devices and the corresponding specific information. This table is called a point table. The data point number in the point table can be mapped one by one with the information address body in the IEC60870-5-104 message, and the device name in the point table can correspond to the device operating status information of IEC60870-5-104.

[0004] The dispatch center can obtain correct telecontrol information, and the normal operation of the telecontrol system is the premise to ensure that the dispatch center can correctly monitor the substation. However, in order for the dispatch center to obtain correct telecontrol information, it must ensure that the information stored in the dispatch master station table in the dispatch master station is consistent with the actual information of the corresponding substation equipment.

[0005] Substation point-to-point is to check the information received by the dispatching master station with the actual information of the substation equipment. Point-to-point is to compare the actual information of each device in the substation with the information received by the dispatching center, so as to find out the error information stored in the dispatching center point table, and also to perform functional tests on the telecontrol device, graphic gateway machine, and alarm direct transmission machine. Point-to-point is mainly used for acceptance and later maintenance of smart substations during the commissioning stage.

[0006] The traditional point-to-point method is complicated and cumbersome, and the point-to-point work needs to be done at a long distance between the dispatching master station and the substation. The specific process is as follows: First, the staff of the dispatching master station contacts the staff of the substation through a telephone connection, and the staff of the substation manually acts on the primary equipment as an input stimulus; then, the dispatching center receives the output information corresponding to the input stimulus, and manually verifies the action information of the primary equipment input by the substation with the information received by the dispatching center, and finally completes the point-to-point work. Therefore, the point-to-point work in the prior art adopts a manual method, which brings a series of inconveniences to the staff of the substation and the staff of the dispatching center. At the same time, the manual point-to-point method also violates the development trend of intelligent substations with intelligent and unmanned operation. Summary of the invention

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.

[0066] 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 sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

[0067] As introduced in the background technology, the prior art adopts manual methods to perform point alignment, which brings a series of inconveniences to the substation staff and the dispatch center staff. In order to solve the problem that the prior art requires staff to operate at the substation and the dispatch center respectively, and to intercept data respectively and perform manual point alignment operations, which is cumbersome and inefficient, the embodiment of the present application provides an automatic calibration system for substation sites.

[0068] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0069] Figure 1 1 is a structural block diagram of an automatic calibration system for a substation provided according to an embodiment of the present application. Figure 1 As shown, the substation automatic calibration system 10 includes: 101, a simulated MMS module; 102, a telecontrol system; 103, a simulated dispatching master station module; 104, an automatic point-to-point module, which are specifically as follows:

[0070] The simulation MMS module 101 is used to generate a target MMS message based on the historical MMS message of the substation control layer, and generate a first calibration point table. The object of the target MMS message includes all primary devices of the substation. The first calibration point table includes at least address information of the object, real-time image of the object and alarm information of the object.

[0071] The main function of the simulation MMS module is to generate the target MMS message based on the historical MMS message of the substation control layer, and generate the first calibration point table accordingly. This module simulates all primary devices (such as switches, circuit breakers, transformers, etc.) in the substation, and includes the address information, real-time images and alarm information of these devices in the first calibration point table.

[0072] Through this module, the system can accurately simulate and record the current status of the substation primary equipment, which helps to ensure that the information received by the dispatch center is consistent with the actual information of the substation in the subsequent steps. The information contained in the target MMS message lays the data foundation for the system's automatic proofreading and improves the integrity and accuracy of the substation equipment information.

[0073] The telecontrol system 102 is connected to the simulation MMS module for communication. The telecontrol system is used to receive the target MMS message sent by the simulation MMS module and generate an IEC104 message and a DL476 message. The IEC104 message includes the telemetry data and telesignaling data of the object in the target MMS message. The DL476 message includes the device alarm data and device graphic data of the object in the target MMS message and the operation data information corresponding to the device graphic data.

[0074] The telecontrol system is responsible for receiving the target MMS message sent by the analog MMS module and converting it into IEC104 message and DL476 message. IEC104 message includes telemetry data and telesignaling data of substation equipment, and DL476 message includes alarm data, equipment graphic data and operation data information of equipment. These messages are the main basis for the dispatch center to receive and interpret substation equipment information.

[0075] The telecontrol system converts MMS messages into IEC104 and DL476 messages, so that substation equipment information can be received and processed in the format required by the dispatch center, increasing the compatibility and versatility of the system and ensuring the consistency of information during transmission between different systems.

[0076] The simulation dispatching master station module 103 is connected to the telecontrol system for communication. The simulation dispatching master station module is used to receive the IEC104 message and the DL476 message sent by the telecontrol system, parse the IEC104 message and the DL476 message by the simulation dispatching master station, and generate a second proofreading point table, which includes the device name and device information of the object and the wiring diagram of the substation;

[0077] The simulation dispatching master station module is connected to the telecontrol system and is used to receive IEC104 messages and DL476 messages. The module simulates the dispatching master station to parse the received messages and generate a second proofreading point table. This point table contains the device name, device information, and the wiring diagram of the substation, providing the dispatching center with a full picture of the device status.

[0078] This module provides the dispatch center with a global view of the substation, ensuring that the dispatch center can obtain the name, status and wiring information of each device, facilitating the visual management of information. At the same time, the module provides the necessary data support when the dispatch center conducts point-to-point, increasing the accuracy of the data and the efficiency of proofreading.

[0079] The automatic point alignment module 104 is in communication connection with the simulated MMS module and the simulated dispatching master station module, and is used for performing automatic point alignment operation according to the first calibration point table and the second calibration point table.

[0080] The automatic point alignment module is connected to the simulated MMS module and the simulated dispatching master station module, and is used to automatically align the first and second calibration point tables. The module verifies the consistency between the point table data stored in the dispatching center and the actual substation information by comparing the equipment information in the first and second calibration point tables.

[0081] The automatic point-to-point module greatly improves the efficiency and accuracy of proofreading through the automated proofreading process, avoids errors caused by manual proofreading, and can promptly detect and correct possible erroneous information in the dispatch center point table, thereby improving the accuracy of information and the reliability of system operation.

[0082] Therefore, the automatic calibration system for substations provided by the present application realizes the automatic collection, message generation, data format conversion, information analysis and automatic calibration of substation equipment information through the collaborative work of the simulated MMS module, telecontrol system, simulated dispatching master station module and automatic point-to-point module. The system not only improves the management efficiency of the dispatching center for substation equipment information, but also reduces the error of manual calibration, ensures the consistency between the equipment information received by the dispatching center and the actual substation equipment status, thereby ensuring the dispatching center's accurate monitoring of the substation and improving the safety and stability of power grid operation.

[0083] Figure 2 is a structural block diagram of a telecontrol system provided according to an embodiment of the present application. Figure 2 As shown, the telecontrol system includes: 1021, telecontrol gateway; 1022, alarm direct transmission gateway; 1023, graphic gateway, as follows:

[0084] The telecontrol gateway 1021 is used to receive the target MMS message, parse the telemetry data and telesignaling data in the target MMS message, and generate an IEC104 message based on the preset telecontrol communication protocol according to the telemetry data and telesignaling data;

[0085] The main task of the telecontrol gateway is to receive the target MMS message and parse the telemetry data and telesignaling data therein. After parsing, the telecontrol gateway generates an IEC104 message according to the preset telecontrol communication protocol (such as IEC 60870-5-104). Telemetry data usually contains the real-time status information of the equipment, while telesignaling data is used to indicate the switch status of the equipment (for example: whether the circuit breaker is closed).

[0086] By effectively converting the telemetry and telesignaling data in the target MMS message into IEC104 message, the telecontrol gateway improves the data transmission capability between different communication protocols, ensuring that the dispatch center can obtain the status information of the substation equipment in a timely manner, thereby enhancing the real-time performance and reliability of the system.

[0087] The alarm direct transmission gateway 1022 is used to receive the target MMS message, parse the alarm information in the target MMS message, and generate the device alarm data in the DL476 message based on the preset real-time data transmission protocol according to the alarm information;

[0088] The alarm direct transmission gateway is responsible for receiving the target MMS message and parsing the alarm information in it. Based on the parsed alarm information, it generates the equipment alarm data in the DL476 message through the preset real-time data transmission protocol (such as MQTT, HTTP, etc.). These alarm data can reflect the fault or abnormal status of the substation equipment.

[0089] The existence of the alarm direct transmission gateway makes the transmission of alarm information more efficient and timely, thus helping the dispatch center to quickly understand the abnormal status of the equipment and take corresponding measures. This function significantly improves the system's response speed to emergencies and helps maintain the safe operation of the substation.

[0090] The graphic gateway 1023 is used to receive the target MMS message, parse the real-time image and real-time operation data in the target MMS message, and generate the device graphic data and operation data information in the DL476 message based on the real-time image and real-time operation data based on the preset real-time data transmission protocol.

[0091] The function of the graphic gateway is to receive the target MMS message, analyze the real-time images and operation data therein, and generate the equipment graphic data and operation data information in the DL476 message through the preset real-time data transmission protocol based on this information. This includes the status diagram of the equipment, wiring diagram, etc., which can provide intuitive information display for the dispatch center.

[0092] By providing real-time images and operating data of equipment, the graphic gateway enhances the dispatch center's visual management of substation equipment status. Dispatchers can understand the equipment operating status more intuitively, which helps to make quick judgments and decisions, and improves work efficiency and accuracy.

[0093] Through the comprehensive application of telecontrol gateways, direct alarm transmission gateways and graphic gateways, a complete telecontrol information processing mechanism has been formed. This mechanism not only realizes the effective analysis and conversion of telemetry, telesignaling, alarm information and real-time images in the target MMS message, but also ensures that this information is transmitted to the dispatch center in an efficient manner through appropriate protocols. The high efficiency and real-time nature of this information transmission significantly improves the dispatch center's ability to monitor the status of substation equipment, enabling it to obtain and respond to equipment status changes in a timely manner, ensuring the safe and stable operation of the power grid. Through the accurate transmission of equipment status and alarm information, the system can effectively reduce fault response time and improve the operation and maintenance efficiency and management level of substations.

[0121] The first message parsing module extracts the specified original message from the IEC104 message storage module for parsing according to the second target instruction. The parsed message data is matched with the substation point table to obtain the first parsing result and store it in the IEC104 message storage module. This module deeply parses the original message and matches the message data with the point table information, so that the system can quickly obtain the operation information of the equipment, ensure the accuracy of the equipment information obtained by the dispatch center, and significantly improve the consistency of the system data and the grasp of the equipment status.

[0127] As a possible implementation method, the automatic point-to-point module is also used to capture the first proofreading point table from the simulated MMS module, capture the first parsing result from the simulated IEC104 master station module of the simulated scheduling master station module, and match the objects included in the first proofreading point table and the first parsing result. When all objects are matched, it is determined that the proofreading is passed, and the first parsing result includes the device name and device information of the second proofreading point table.

[0128] Specifically, the automatic point-to-point module captures the first proofreading point table from the simulated MMS module, which contains the basic information of the substation equipment (such as equipment name, address, real-time image, alarm information, etc.). This process is the first step of the automatic point-to-point operation, ensuring that the data of the dispatch center can be reliably supported from the source. The automatic point-to-point module directly captures the proofreading point table from the simulated MMS module, avoiding the delay of manual query and data transmission, improving the real-time and accuracy of the system's substation equipment information, and providing a reliable data source for subsequent point-to-point matching operations.

The result contains the device name and device information obtained from the IEC104 message parsing, etc., and is intended to verify the received telecontrol data with the information stored in the dispatch center. Capturing and using the first parsing result can ensure that the system can effectively match the on-site equipment information based on the equipment information transmitted by the telecontrol system, which helps to timely discover data inconsistencies or errors and enhance the dispatch master station's control over the equipment operation status. The automatic point-to-point module matches the object information in the first proofreading point table and the first parsing result to ensure that each object in the proofreading table can find a corresponding one in the parsing result. The matching content includes detailed information such as device name, address, and real-time status to ensure that the telecontrol data of the dispatching master station system is consistent with the real device information on site. Through object matching, the system can automatically verify the consistency of the data of the dispatching center and the data of the on-site equipment, reduce the monitoring error caused by data errors, and provide data guarantee for remote monitoring and real-time management. When the automatic point-to-point module confirms that all object matches have passed, the system automatically determines that the proofreading operation has passed, indicating that the data of the dispatching master station is completely consistent with the on-site device information, and no further manual intervention or data correction is required. Setting the conditions for proofreading not only simplifies the operation process, but also reduces unnecessary repeated verification work, improves the work efficiency and reliability of the system, and ensures that the substation data has high accuracy after automated proofreading.

[0129] The automatic point-to-point module can automatically complete data capture, object matching and proofreading result determination, forming a complete automatic point-to-point process. By capturing the first proofreading point table and the first parsing result, the system can automatically complete the consistency check of the dispatching center and substation equipment information. The object matching process ensures the proofreading of each piece of information, avoiding the errors and inefficiency of traditional manual verification. When all objects are matched, the proofreading is automatically determined to be completed, further reducing the need for manual intervention, so that the system can efficiently and accurately complete the automatic proofreading operation on the basis of maintaining the safe and stable operation of the power grid. This system design greatly improves the automation level and data consistency of the power system, and provides technical support for the precise operation of the dispatching system.

[0136] After receiving the fourth target instruction, the second message parsing module grabs the original alarm data in the DL476 message from the first real-time storage module, performs detailed parsing, extracts the alarm information of the equipment and generates the second parsing result. At the same time, the module visualizes the parsing results to facilitate monitoring personnel to intuitively view the alarm status. Extracting and visually displaying the equipment alarm data not only improves the processing speed of the alarm information, but also improves the readability and intuitiveness of the information, enabling dispatchers to quickly locate equipment problems, reduce response time, and improve the overall operating efficiency of the system.

[0140] According to the fifth target instruction of the human-computer interaction interface, this module generates the corresponding APDU (application protocol data unit) for the alarm data in the received DL476 message to simulate the response of the telecontrol system to the dispatching master station. The generated APDU can simulate the transmission of alarm information to the dispatching master station, effectively test the response of the dispatching system to the actual alarm event, verify the response accuracy and reliability of the system, and improve the early warning and response processing capabilities of the system.

[0141] The analog alarm direct transmission master station module constitutes an integrated alarm data processing and feedback system through a series of communication, data acquisition, analysis and feedback functions. Data transmission through Socket and TCP / IP ensures real-time and reliability, while the layered message acquisition and analysis mechanism enables data to be quickly classified, stored, deeply analyzed and displayed, thereby improving the system's response efficiency and the readability of alarm information. At the same time, the real-time storage module and feedback module ensure the efficient interaction and feedback capabilities of data between the modules of the system, providing reliable alarm information support for the dispatching center, and making the system more reliable and responsive in the substation environment. This module has a significant safety improvement effect in the entire substation station meter automatic proofreading system.

When receiving the second protocol control frame fed back by the alarm direct transmission gateway, it synchronously receives the DL476 message transmitted by the alarm direct transmission gateway. The DL476 message is transmitted in the basic data frame format of the DL476 protocol.

[0143] Specifically, the analog alarm direct transmission master station module requests the alarm direct transmission gateway to establish a communication connection by sending a first protocol control frame. The control frame follows the specification of the DL476 protocol to ensure that the format and content of the information meet the communication requirements. The connection request is made through a formal protocol control frame, which ensures the standardization and reliability of communication, reduces communication failures caused by format errors, and improves the compatibility and stability of the system. Once the alarm direct transmission gateway successfully receives the first protocol control frame, it will return a second protocol control frame as feedback to indicate the result of the connection request. The feedback frame contains information about the connection status, indicating whether data transmission can be performed. Through the feedback mechanism, the analog alarm direct transmission master station module can promptly obtain the status of the connection request to ensure that subsequent data transmission is performed at the appropriate time.

The synchronous receiving mechanism improves the real-time performance of data processing, ensures the rapid transmission and processing of alarm information, effectively reduces the potential risk of delay, and enhances the system's responsiveness to real-time monitoring of substations. During transmission, the DL476 message follows the basic data frame format of the DL476 protocol, which defines the structure and content of the data frame and ensures accurate transmission and parsing of information. The standardized data frame format enhances the interoperability of the system, simplifies the data parsing process, ensures that information can be correctly identified and processed, improves data processing efficiency, and reduces the risk of potential data loss or misinterpretation.
