Measurement Class Phasor Measurement Unit Compliance for Electrical Grid Monitoring

This article offers synchrophasor transient and steady compliance with IEC/IEEE 60,255-118-1:2018 standard. This power system standard is mainly designed for the synchronized phasor measurement and specifies the synchronized voltage and current phasors, frequency and derivative requirements, time tag, and synchronization of all measurements. The Synchrophasor testbed includes three-phase high-precision power and current signal voltage, system time unit, GPS receiver, server PC, electricity standards, PMUCAL and test-based PMU software. Three-Phase Measurement Units (PMUs) from different machines have been tested individually to confirm compliance with the state-of-the-art international standard, which is essentially a dual logo standard. Such measured information is being used to control the power grid by smart communication utility. The test results of synchrophasor have been analyzed and discussed.
