Abstract

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 system. Based on the short circuit current calculation and analysis after the wind farm connected to distribution network, the adaptive instantaneous protection is put forward to solve the problem of malfunction or refusal that original instantaneous protection may appear, and the reliability of the protection is improved.
