Misoperation-preventive locking logic automatic test system for intelligent transformer substation

Abstract

The invention discloses a misoperation-preventive locking logic automatic test system for an intelligent transformer substation, comprising a data layer, a business layer and a presentation layer, wherein the data layer comprises a GOOSE (Generic Object Oriented Substation Event) message receiving and sending module for receiving a GOOSE signal, a switch and disconnecting link deflection signal and a switching value signal from a monitoring system of the intelligent transformer substation and sending the received data to a comparison and analysis module of the business layer, and an SCD (Science Citation Database) file parsing module for analyzing the GOOSE signal from the system of the intelligent transformer substation; and the business layer comprises a standard library for storing an input misoperation-preventive locking logic database, and the comparison and analysis module used for performing real-time logical operation by different switch and disconnecting link position combinations received from the GOOSE message receiving and sending module according to the input misoperation-preventive locking logic database, comparing the standard output result with the locking result fed back by a monitoring device and verifying validity of the misoperation-preventive locking logic of the monitoring device. The system can verify the validity and integrity of the misoperation-preventive locking logic of the monitoring device.

Description

technical field [0001] The invention relates to an intelligent substation anti-error locking logic test system, which belongs to the technical field of electric power automation. Background technique [0002] Compared with traditional substations, smart substations have undergone major technological innovations in equipment information collection, information sharing, and equipment control. The secondary equipment of the traditional substation adopts a decentralized collection method, and each equipment collects corresponding data independently; the smart substation greatly utilizes the advantages of the network, adopts the method of centralized collection and data sharing, and distributes the switch and analog quantity acquisition modules to the equipment itself. After digital processing, it is transmitted to the protection device or high-speed Ethernet switch, realizing one-time collection and data sharing. The equipment switching signal acquisition module - intelligent t...

Problems solved by technology

[0003] The verification of the anti-misoperation locking logic function of the substation monitoring system is closely related to the position signal of the switch equipment. In the initial stage of the integration test or field test, the position signal needs to be simulated through temporary wiring, and the test preparation Heavy workload

[0004] The debugging of the traditional substation anti-mislocking logic generally needs to be verified by simulating the position of the switch switch. To complete the different combinations of all the switch switch positions is not only a heavy workload, but also easy to miss
