Abstract

The invention relates to a substation secondary automation equipment stable operation control method. A substation secondary automation equipment stable operation control system architecture building method and an information transfer flow are included, and equipment stable operation is monitored through the change of a secondary automation equipment operation index. According to the method, maintenance personnel can be periodically reminded to maintain secondary automation equipment, an equipment fault characteristic is judged when the equipment is failed, a fault impact scope is defined in case of a batch of failures and a fault processing assistant decision is given, and the operation of the substation secondary automation equipment in an ill state or with extended service is prevented.
