The Study on Configuration and Setting of Relay Protection when Distributed Generation Accesses to Distribution Network

Abstract:

When distributed generation (DG) accesses to non-system bus , and the power capacity increases to a certain extent, it will cause malfunction of protective devices, as a result of which ,protective devices lose selectivity. This paper analyzes influence to relay protection of power system as a result of the access of DG, establishes a model of the access of DG, and proposes principles of reconfiguration of protection devices, and re-setting of relay protection when DG accesses to power system. This method provides a theoretical basis for designing of DG accessing to power system, reconfiguration of protection devices and re-setting of relay protection.
