广域同步测量技术在智能电网保护与控制中的应用

Application of Wide Area Synchronized Measurement in Protection and Control of Smart Grid

以同步相量测量装置为基础构建的广域测量系统不断扩大和完善,为电力系统的观测提供了重要的数据支撑。随着智能电网建设的不断推进,对同步相量测量的实现方式及其应用提出了许多新的思路,这些思路都是来自于现实应用的需求,但总体上呈发散的状态,没有统一的原则。文中建立了时—空协调分析的原则,从系统能观和能控2个方面,对广域同步测量的物理条件和协议支撑进行了深入地分析,提出了广域同步测量技术在智能电网中的实现方式以及电网保护与控制中的应用。

The synchronized phas or measurement based the Wide Area Measurement System is expanding and improving constantly, which provides important data to support power system observing. With the development of the Smart Grid, many new ideas about the synchronized phaosr measurement and application are proposed for reality applications. But those ideas are not systematized due to there isn＇t a unified principle to follow. This paper proposes a principle of time-space coordination based on the physical conditions and protocol support from the aspect of observability and controllability, and then introduces the application of wide area synchronized measurement in the protection and control of Smart Grid.
