Phasor Measurement Unit Test Under Interference Conditions [PDF]
IEEE Transactions on Power Delivery, 2018 This paper investigates the performance of phasor measurement units (PMUs) under interference conditions, which can appear in a power system and are not tested by the C37.118.1 standard. Three PMUs from different vendors configured for the M-class requirements were used to test three possible interference condition scenarios.
