| 摘 要： | 能观性和能控性是大系统保护的基本目标,电力系统的SCADA,PMU及其它监控设备都为这2个目标实现提供数据.从时空协调的角度分析电力系统的控制问题,认为PMU提供某个尺度上(例如:10ms时间尺度以及220kV以上变电站空间尺度)观察和控制电力系统的基本数据;并分析智能变电站PMU功能的实现,给出基于PMU的广域保护配置方案,为智能电网建设提供参考.

| Abstract: | Observability and controllability are the purposes of large scale power systems protections.Data recorded by SCADA,PMU or other units are employed for the purposes implementation.The problem of power system control is analyzed from a viewpoint of space-time cooperation in this paper.PMU provides some data to observe and control the power system in certain scale(for example,10 ms time scale and 220 kV or more space scale).And the PMU function implementation is analyzed.The PMU configuration scheme based on w... |
