Phasor Measurement Technology Based Power System Monitoring and Control
نویسندگان
چکیده
The concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase angle response signals using Fourier Transforms or Short Time Fourier Transform, Prony or Wavelet analysis technique or any other combination among those methods. Moreover, using the wide area signal provided by PMU, power system stability control also gain benefit through the wide area control technique where the system provide a better response toward the inter-area oscillation compared to the conventional damping controller. Finally, at the end of this work, the application of phasor measurement technology in the small signal stability monitoring and the wide area control based on phasor measurement data are discussed.
