Traditional relay protection methods for doubly-fed wind farms have the problem of phase current distance protection mismatch. As a result, the protection boundary is too small. A relay protection method of doubly-fed wind farm considering the transient characteristics of wind power is designed. The flux equation was substituted into the voltage equation to obtain the differential current parameters of the double-fed wind farm, extract the transient characteristics of wind power, reduce the electromagnetic torque command value of the generator, adopt the connection mode with zero sequence compensation, adjust the interphase current distance protection, set the minimum threshold for the current vector, and design the relay protection mode of action. Experimental results: average value of relay protection boundary of the relaying protection method of the double-fed wind farm in this paper and the other two relaying protection methods are 57.888%, 41.955% and 38.397% respectively. Indicating that the relaying protection method of the doublefed wind farm considering the transient characteristics of wind power has better performance.
