Description

Technical Field

[0001] The present invention relates to the technical field of Baoxin substation configuration acceptance, and in particular to a Baoxin substation configuration acceptance method and system based on multi-scenario adaptability. Background Art

[0002] The power system relay protection and fault information system consists of two parts: the main station and the substation. At the plant station end, the substation of the security system communicates with intelligent electronic devices such as relay protection, fault recorders, and safety automatic devices to collect normal operation, abnormal alarms, and fault information from these devices. After preliminary processing, it is uploaded to the main station located at the dispatching end. The substation of the security system needs to collect information from different manufacturers and models of protection devices and upload it to the main station. Therefore, the security substation must maintain normal communication with each protection device and be able to correctly parse the various information uploaded by the protection device. However, the security substation is faced with a large number of protection devices and a variety of protection device communication protocols.

[0003] Currently, on-site testing of Baoxin substations connected to protection devices primarily utilizes interoperability testing. This involves interconnecting the Baoxin substation with the on-site protection devices during on-site acceptance testing. Testers are required to record and test each protection device individually according to specific acceptance standards and requirements. This workload is substantial, and the testing process is prone to omissions, resulting in incomplete testing. Furthermore, non-standard implementation of the protection device's communication protocol can directly impact the Baoxin substation's ability to connect to other protection devices using the same protocol.

[0004] Prior art document 1 (CN 102821010 B) discloses a protection device simulator, comprising: a public dispatching module, a protection device behavior simulation module connected to one end of the public dispatching module, a communication protocol simulation module connected to the other end of the public dispatching module, and a communication interface connected to the communication protocol simulation module. The simulator focuses on the normal communication between the protection substation and the protection device and the correctness of information analysis. The operation content is complicated and the function is single, and it cannot verify the correctness of the protection substation information.

[0005] Prior art document 2 (CN 102403788 B) provides a test system suitable for the Southern Power Grid's security system, including a human-machine interface, a test case database, a communication message and device information database, a master station simulation tool, a communication front-end and a communication interface. The system automatically determines the configuration correctness and information integrity of the fault information substation by verifying the consistency between the configuration information in the substation and the read information in the master station. However, this method only accepts the security substation information when the security system fails to operate.

[0006] Prior art document 3 (CN 109495290 A) discloses a method and system for interaction between a master and a substation of an operation and maintenance system. However, the method only involves information transmission between a main station and a substation, cannot guarantee the timeliness of information transmission, and the information involved is not comprehensive enough.

[0007] In short, during the specific project implementation process, the following problems exist: the workload of manual acceptance is large. Due to the large number of devices, manual verification of substation configurations item by item directly leads to the inability to complete the acceptance and verification of all items manually, and the acceptance work efficiency is extremely low. Summary of the Invention

[0008] In order to address the deficiencies in the prior art, the present invention provides a method and system for the configuration acceptance of a trustworthy substation based on multi-scenario adaptability.
