Abstract
This paper proposes a practical mitigation solution to the voltage sag problem by resonant grounding for a 22-kV distribution system of Provincial Electricity Authority (PEA). The simulation is carried out to investigate the voltage sag impact at the low voltage side of the delta/wye distribution transformer connected at the fault location in the existing solidly grounded system and proposed resonant grounded system by ATP-EMTP simulation. The results indicate that the proposed resonant grounding can help all customers connected at the same bus survive from voltage sag problems and also keep the customers on the faulty feeder connected to the system being continuously supplied. In addition, the distribution system with resonant ground lengthens the useful lifetime of the upstream circuit breaker of the feeder as its number of operations is significantly reduced.
