Phasor Measurement Unit (PMU) devices, based on the synchronized measurement technology, are basic building blocks of Wide Area Monitoring System (WAMS) and Wide Area Monitoring Analysis Protection-control (WAMAP). Similar to the Remote Terminal Unit (RTU) in Energy Management System (EMS), PMU is becoming very important in the WAMS or WAMAP. This paper introduces the architecture of PMU testing and evaluation (T&E) in our laboratory. The integrated evaluation schemes include testing environment, performance testing method, conformance testing method and evaluation.
