Relay Protection Vector Measurement
This paper studies vector surge estimation methods of four different commercial relays. Simulations of frequency and rate of change of frequency (ROCOF) variations, phase angle changes, islandings, short-circuits, and transmission events. The recently reported occurrences showed the spurious tripping of DG has been caused due to sensitive LoM settings, mainly by vector surge (VS, 78VS or vector jump) and ROCOF (81R) functions ,. 1547-2018 recommended ride-through requirements for which the LoM protection must ride-through during. The 78VS principle of operation is based on the phase displacement of voltage measured in the terminals of a synchronous generator operating in parallel with the grid when unintentional islanding occurs. When there is a sudden disconnection of the generator and the grid, the frequency accelerates (or decelerates) based on the power imbalance at the.
