主要介绍电网动态稳定实时监测系统监测原理、组成及功能 ,提出利用 GPS同步时钟 ,同步测量功角和异地母线相位的方法 ,并通过所研制的厂站端监测装置和通信系统将状态和工况参数实时传送到调度端装置 ,从而实时监测机组和电网的动态和暂态行为 ,直接监测稳定性 ,并可用于稳定控制。 This paper mainly introduces the monitoring principle, composition and function of dynamic real-time monitoring system for power grid. The method of using GPS synchronous clock to synchronously measure power angle and remote bus phase is proposed. The status and working conditions of power grid monitoring system and communication system The parameters are sent to the dispatcher in real time to monitor the dynamic and transient behavior of the unit and grid in real time, directly monitor the stability and can be used for stable control.
