Abstract
In this chapter, wide area measurement systems (WAMS), which are one of the cornerstones in modern power systems, are overviewed. The WAMS has great applications in power system monitoring, operation, control, and protection systems. In the modern power systems, WAMS is adopted as a base for the modern monitoring and control techniques. Therefore, an introduction of WAMS is firstly provided. Then, phasor measurement unit (PMU), which is the base of WAMS, is described. Afterward, the most recent developments in power system estimation, stability, and security techniques, which are based on WAMS, are introduced. Later, general system setup for WAMS-based under-frequency load shedding (UFLS) is provided. Finally, the required communications infrastructures are comprehensively discussed.
