Abstract

The invention discloses a relay protection equipment status identification method based on a BP neural network. The status of the relay protection equipment can be in details identified by the identification method, and thus the relay protection equipment is guided to take corresponding protection measures for different defaults; by adopting the identification method, a problem that various operating conditions are difficult to be compatible due to single mode of the relay protection equipment is solved, influence of faults on the equipment is reduced to a great extent, and the equipment is prevented from being seriously damaged.

Description

technical field

[0001] The invention relates to a state recognition method of relay protection equipment based on BP neural network, which belongs to the field of state recognition of relay protection equipment in substations. Background technique

[0002] The smart substation takes the primary and secondary equipment of the substation as the digital object, based on the high-speed network communication platform, and realizes information sharing and interactive operation inside and outside the station by standardizing digital information. In the development of smart substations, the large-scale use of smart devices has also brought some problems. Compared with the traditional substation, the smart substation moves the secondary equipment data acquisition equipment that should have been placed in the relay room to the primary equipment area, and the data acquisition equipment is weak current equipment, which is extremely vulnerable to the electromagnetic environment in the pr...
