Abstract :
With the increase of wind plants integrated to the power system, the effect of the wind power generation on the system has become more and more severe. The connection of wind power plant changes the short-circuit current in distribution network. Protections now used must be adjusted and changed to ensure correct fault clearing with right method, and maintain the safe and stable operation of the distribution system. In this paper, cases including the wind farm cut-in and cut-off, wind different farm capacity, different integration points, and different fault types have been studied to get changes of fault current. After detailed investigation, an adaptive algorithm is proposed to deal with the effect of wind farm integration on relays in distribution system. A model system in Matlab/Simulink is used to show the effectiveness of the proposed algorithm.
