Test method for parameters of wind farm dynamic model

The invention discloses a test method for parameters of a wind farm dynamic model. Under the conditions that a wind farm unit and reactive power compensation equipment work stably, the wind speed is stable and is between a cut-in wind speed and a rated wind speed, and the wind farm force output is smaller than a rated force output, a wing-speed transition disturbance test, a wind farm tripping/input unit disturbance test, a wind farm power variation test, a wind farm reactive power compensation equipment disturbance test, a near-wind farm water and fire power farm tripping machine disturbance test and a manual uniphase grounded short circuit test at the wind farm outgoing line part are completed, and operation curves of the wind farms under all conditions are recorded so as to complete parameter test. Therefore, the advantages of providing accurate measurement data for stability analysis of an electric power system and power network dispatching are achieved.
