Abstract:  To meet the demands of secondary equipment information for power grid operation and intelligent dispatching, the online monitoring and fault diagnosis system for smart substation secondary equipment is constructed in Anhui provincial power grid to realize the remote inspection and operation, state monitoring and warning, analysis of fault diagnosis and action behavior of relay protection devices. Combined with the practice and application of pilot system, this paper introduces the construction demand and realization of the hardware structure, software structure and functional module. And a look-ahead is presented for future technology development in promoting the online monitoring and fault diagnosis system. Through the construction and application of the system, it provides decision-making basis for dispatchers to deal with power grid faults quickly and effective technical support for the fault elimination and condition based maintenance of secondary equipment in intelligent substations.

Key words: secondary equipment, online monitoring, fault diagnosis
