When the effects of wind farms on power system are researched, to save the calculation time the simplified model of asynchronous motors are often used or the wind-farm consisting of many wind-turbines can be simplified by multi-machine dynamic aggregation. Here, an aggregation method for parameters identification of many asynchronous generators based on the concept of the transfer function of synchronous generator is put forward, in which the synchronous reactance, transient reactance and rotor time constant are calculated by least square method. The aggregation of three asynchronous generators is simulated by MATLAB/SIMULINK and the simulation results show that the presented method is effective.
