Micro-Grid Fault Transient Characteristics and Relay Protection

Abstract:

Micro grid can minish the impact from fluctuation of distributed generator by control and management system as a new type of power system. But micro-grid also brings disadvantages on power attemperation, function and relay protection. Firstly the inverter’s electric model is built and the fault transient is simulated. Inverter interfaced distributed generator shows evident non-linear characteristic for the limits on power and current from control system. In this paper, according to the fault transient simulation results, analysis of the problems faced by the existing relay protection and corresponding solutions is given respectively.
