Abstract

The invention relates to a whole-group verification method and system for a network virtual secondary loop of an intelligent substation. The method comprises the following steps: acquiring a CID (Configured IED Description) file and an ICD (IED Capability Description) file of IED equipment to be verified and an SCD (Substation Configuration Description) file of the intelligent substation, and extracting configuration description specific to the IED equipment in the SCD file; extracting SV configuration and GOOSE configuration in the configuration description, and generating an SV test message and a GOOSE test message according to the SV configuration and the GOOSE configuration; receiving a test parameter input by a user, extracting equipment characteristics in the configuration description, and generating a protection logic verification message; sending the messages to the IED equipment respectively; and receiving an action message returned by the IED equipment to be verified, and judging that the IED equipment to be verified works normally if the action message is consistent with a pre-stored action reference message. Through adoption of the whole-group verification method and system, the complexity degree of the secondary loop in an intelligent power grid is lowered; operation of periodical verification personnel is reduced; and power failure time in a whole-group verification process is shortened.

Description

【Technical field】 [0001] The invention relates to power electronics technology, in particular to a method and system for verifying a whole set of virtual secondary circuits in an intelligent substation network. 【Background technique】 [0002] With the development of smart substation communication transmission technology, the information transmission mode of smart substations has changed from the analog transmission of electrical signals using cables as the medium in conventional substations to the digital transmission of digital signals using optical fibers as the medium. The digital transmission method realizes the distributed functions of the substation secondary system such as monitoring interlocking, protection sampling, tripping and closing, starting, and blocking. [0003] After the smart substation is put into operation, it is necessary to carry out regular inspections on various IED (Intelligent Electronic Devices, intelligent electronic devices) equipment in the net...
