Abstract

The performance of Phasor Measurement Units (PMUs) is essential and must ensure accuracy before installation in the substation. In the field, various interference conditions would occur in the power systems and were tested as per IEC/IEEE 60255.118.1:2018. Three number of PMUs from different manufacturers was configured for the M-class and P-class requirements. They were tested for two interference condition scenarios. The first case injected single harmonics with the input to test the impacts on accuracy. The second scenario was considered for inter-harmonics and checked the accuracy of PMUs. This will be useful in selecting high-quality PMUs, to obtain the most precise and dependable measurements under real-time power system operating conditions, the testing procedures, findings, and analysis are presented in this paper.
