The intelligent grid promotes the information and digital construction of the power system,and the secondary circuit equipment and its protection device of the power system will produce a large amount of data and information during the operation and maintenance.Through data mining,the intelligent monitoring of the system can be realized,which provides an important guarantee for the stable operation of the power grid.Relay protection is an important guarantee for the normal operation of power system.The combination of big data mining technology and secondary protection data can better realize the intelligent development of power system.In this paper,a monitoring strategy of electrical secondary circuit based on big data is proposed,and cloud computing is used to process and analyze the data of electrical secondary protection.This method has strong data analysis ability,realizes the operation monitoring and fault diagnosis of the secondary circuit,improves the security and reliability of power supply effectively,and has good application prospect and practical value.
