Phasor measurement unit (PMU) is an emerging measurement technology for power grids which enables the synchronised high speed measurement with precise time stamps for accurate system comparison over a wide geographic area. PMU measurement quality is the key issue in application purposes. To evaluate the measurement quality, the concepts of total vector error (TVE) and benchmark tests, including the magnitude, phase and frequency step tests, are proposed in the C37.118 standard. It also includes requirements for test results. This paper reports the results of tests performed on several PMUs. These tests include both steady state and dynamic conditions conforming to the new requirements under development by the IEEE for the updated C37.118 standard. In addition to validating the new IEEE requirements with actual PMU measurements, the results evaluated by TVE are discussed and with errors analyzed based on phasor magnitude and angle.
