Abstract

The installation of phasor measurement units (PMUs) around the world enables wide-area monitoring and control applications. To incorporate PMU data in grid operations, system operators must understand, validate, and correct phasor measurements before using them in higher-level applications. In this paper, we first discuss the phasor measurement process that takes place inside a PMU, then we present a phasor state estimator to correlate and validate PMU data across a network, and finally we discuss a two-level interarea mode damping controller using remote phasor measurements.
