智能变电站状态监测技术及应用

变电设备智能状态监测是实现变电站信息数字化、通信平台网络化、信息共享标准化的必要条件．并可根据需要支持电网实时自动控制、在线分析决策、协同互动等高级功能，实现与相邻变电站、电网调度等互动。电力设备智能状态监测不仅可以掌握电力设备当前的运行情况．还可以根据其专家系统利用其运行状态数据库对电力设备进行综合诊断，电力设备智能状态监测系统是实现智能变电站的基础。文中针对目前变电站设备的监测技术。结合近年来该领域的现状和智能电网的发展方向，对变电站智能状态监测系统进行综述。

The Technology of State Monitoring System and its Application in Smart Substation

Intelligent state monitoring of substation equipment is an essential factor to realize digitalization of substation information,networking of communication platform and standardization of information sharing.It can also support real-time automatic control,online analysis and decision,cooperative interaction and other advanced features,thus to realize interaction with neighboring substation and dispatching center when necessary.Intelligent state monitoring of electrical equipment can not only ensure proper operation of electrical equipment,but also realize electrical equipment integrated diagnostics using its run state database based on its expert system,so it is the basis of the smart substation.Focused on the present technology of equipment monitoring in substation and combined with the status in this area and the development direction of smart grid in recent years,this paper gave summary of intelligent condition monitoring system for substations.
