Embodiment Construction

[0037] The present invention is a GOOSE message / switch value conversion method for digital transformation of relay protection, which is suitable for a GOOSE message / switch value conversion device for digital transformation of relay protection, comprising the following steps: the device receives a digital 500kV bus difference GOOSE message protocol for protection action tripping, and output corresponding traditional switch value commands;

[0038] The device receives the traditional switching value command for tripping of the traditional 500kV bus differential protection action, and outputs the corresponding GOOSE message protocol;

[0039] The device receives the GOOSE message protocol of the 500kV bus differential protection action starting side switch failure / blocking reclosing, and outputs the corresponding traditional switching value command;

[0040] The device receives the traditional switch command of 500kV bus differential protection action starting side switch failure...

Abstract

The invention aims to overcome the shortcomings in the prior art, designs a communication method on a GOOSE message / switching value conversion device for digitized relay protection transformation of 500 kV transformer substations, and discloses a GOOSE message / switching value conversion method for digitized relay protection transformation. According to the method, communication under various conditions can be carried out. By adopting the technical scheme, the traditional 500 kV transformer substations can work efficiently after sequential power outage and the digitized relay protection transformation work are carried out according to clusters or intervals, reliable communication connection of traditional protection and digitalized protection is achieved, and the relay protection function and the secondary circuit completeness are guaranteed.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to a GOOSE message / switch value conversion method used for digital transformation of relay protection. Background technique [0002] Traditional relay protection uses secondary cables to transmit electrical signals, while digital relay protection transmits GOOSE message protocol through optical cables. For the digital transformation project of the operating substation, if the traditional relay protection transformation plan is followed, the primary equipment such as the line and the main transformer are sequentially shut down, and the digital transformation of the relay protection equipment is carried out at intervals, there must be both untransformed and transformed relays. Electrical protection equipment. Untransformed traditional line protection, switch protection, bus differential protection, and main transformer protection cannot communicate reliably with the transformed...
