摘要
Abstract
There are significant differences in output characteristics between inverter interfaced distributed generator (IIDG) and rotating machine when accidents occur in power system. An IIDG' s output model was established based on PQ control strategy considering its limited overcurrent ability, and a qualitative analysis was made on IIDG's influence on relay protection and the short-circuit current calculation formulas containing IIDG was duduced. The maximum penetration level of different access point was obtained according to current protection' s state and compared with the penetration level without considering overcurrent limit. To meet the demand of protection of complicated distribution network with high permeability IIDG, a new fault location algorithm was proposed based on zone division and verified by a case study.关键词
