Abstract

The invention discloses an SV and GOOSE synchronous output control method for smart substation testing equipment. The method comprises the following steps: a data distribution module receives an SV message and a GOOSE message sent from a CPU, and sends the SV message to an SV message cache module and the GOOSE message to a GOOSE message cache module; and an MUX switch outputs the SV message in the SV message cache module to a coding and sending module through SV message switching steps, or outputs the GOOSE message in the GOOSE message cache module to the coding and sending module through GOOSE message switching steps. The method provided by the invention has the advantages that synchronous control for the output of SV signals and GOOSE signals through a single optical port or different optical ports of the smart substation testing equipment is effectively achieved; and meanwhile, the number of the optical ports of a battery-powered handheld tester of a smart substation can be effectively reduced, so that the power consumption is lowered, and the effective working time is prolonged.

Description

technical field [0001] The invention relates to the technical field of smart substation testing, in particular to a method for controlling the synchronous output of smart substation testing equipment SV and GOOSE. Background technique [0002] The smart substation is based on the digitalization of information in the whole station, the networking of the communication platform, and the standardization of information sharing. form of transmission. According to certain rules, the message combines the SV or GOOSE information to be transmitted by the IED device, and uses information such as AppID (application identification) to identify some special information of the message. [0003] The protection, measurement and control equipment in the smart substation passively receives the SV message sent by the merging unit and the GOOSE message sent by the smart terminal, and obtains data such as voltage, current and position signal by analyzing the content of the message. Since the pa...
