With the gradual expansion of power system construction, unattended substation is imperative. The number and type of auxiliary equipment and environmental equipment in station operation are relatively large, so to realize the efficient and centralized monitoring and management of the equipment bears the brunt of difficulties. A new solution of plant station running auxiliary equipment and environmental equipment for centralized monitoring system is designed and proposed based on the relative switch information of automatic control and new sensing technology collect equipment. The system realizes centralized monitoring and management on auxiliary equipment and environment in the station operation by the dispatching terminal, after the communication network of electric power and the internal information network sent back the running state data of auxiliary equipment and environmental equipment in the station operation, which not only greatly improves the quality and efficiency of the equipment operation and maintenance, but also provides a new solution for substation communication network operation and maintenance. It can effectively realize unmanned operation and development of substation.
