英文摘要：

According to the principle of wind turbine, the concept of equivalent wind speed is put forward. The method of establishing the equivalent model of wind farm is put forward for the three kinds of different distribution forms of it. Simulation analysis is carried out in the PSCAD/EMTDC to verify the correctness of the proposed model, and the adaptability of the model is verified by the dynamic characteristics.
