Title: Characteristics of Vector Surge Relays for Distributed Synchronous Generator Protection

Abstract

This work presented a detailed investigation on the performance characteristics if vector surge relays to detect islanding of distributed synchronous generators. A detection time versus active power imbalance curve is proposed to evaluate the relay performance. Computer simulations are used to obtain the performance curves. The concept of critical active power imbalance is introduced based on these curves. Main factors affecting the performance of the relays are analyzed. The factors investigated are voltage-dependent loads, load power factor, inertia constant of the generator, generator excitation system control mode, feeder length and R/X ratio as well as multi-distributed generators. The results are a useful guideline to evaluate the effectiveness of anti-islanding schemes based on vector surge relays for distributed generation applications.
