Research of relay protection automation technology application in power system

Aiming at the difficulty of detecting faults of relay protection devices in the prior art,which is not conducive to field maintenance,a new type of relay protection automation technology is designed,and a new relay protection application integrating hardware design and big data algorithms is constructed.The hardware system uses ARM Cortex-M3 processor to realize the state calculation in the working process of the relay,and realize the multi-channel output of the relay protection data.The big data algorithm uses the relay protection state algorithm model and the support vector machine algorithm model to realize the failure analysis and regression analysis of the relay protection.The macro data representation of the relay operation is converted into micro data analysis,which improves the relay application and management capabilities.Experiments show that the scheme of this research has low error and high operating efficiency.
