Abstract

The usage of synchrophasors (synchronized phasors) is considered to be the most promising tool to monitor dynamics of modern electric power systems. Synchrophasors are measured by synchronized measurement units, such as Phasor Measurement Units (PMUs), providing high-speed measurements of voltage, current, and frequency. The PMU, as the most sophisticated time-synchronized tool, has been made possible by advancements in computer technology and availability of Global Positioning System (GPS) signals. Application of synchrophasor technology for wide-area measurement, monitoring, analysis and control of electric power systems can enhance its reliability, efficiency, and resilience. To achieve these benefits synchrophasor technology must be matched by advancements in other areas such as: data communications, instrument transformers accuracy, etc. One very important area is in developing methods and applications, i.e., software that uses the data provided by the PMUs. In this area utilities need huge help from academia. This is why Salt River Project (SRP) has established a joint research program with Arizona State University (ASU) and initiated several research projects. So far in many of them Prof. Heydt has been the Principal Investigator. In this chapter a summary of the results of a few such projects is given:

  • State estimation improvements.

  • The time skew problem in PMU measurements.

  • The integrated calibration of synchronized phasor measurements data.

  • Impact of PMU measurement buffer length on state estimation.

  • Synchronous generator parameter identification.
