Research on the Network Based Protection to Settle the Distribution Networks Three-Phase Short-Circuit Faults with Distributed Generators

Abstract:

A model is established to research on the applicability of network protection in theory. In this model, distributed power generation with constant power (PQ) control mode which is equivalent to a voltage control current source is taken as the research object. Fault ride-through control theory is used to analyze the influence on the network protection exerted by three-phase short-circuit fault. In this paper, the equivalent model of the distributed generation is offered firstly. Then the three-phase short-circuit fault characteristics are illustrated based on the equations of the access points voltage and the distributed generations current. In the end, a simulation model is built to verify that the network protection can be applied to settle the three-phase short-circuit fault in the distributed network with distributed generation.
