A wind farm with the regional power grid reactive power control method of coordination

The present invention discloses a coordinated windfarm reactive power control method and the grid area, comprising a) establishing a voltage control region model; 2) Upload windfarm real and reactive power capacity operating state, the master station received in real time scheduling and tracking control command execution; 3 grid operating-state data) acquired in real-time scanning SCADA; 4) in accordance with operating conditions of the grid running state decision data; 5) of the central decision-making and the wind farm network bus according to the voltage state; 6) the voltage control of the secondary area update programming model, the use of the wind farm reactive power regulation, reactive power output distribution; 7) by solving the quadratic programming algorithm to obtain the power grid substation and wind farm area control strategy. The present invention, in reactive power regulation capability of full wind farm on a variety of reactive power sources in the wind power plant and regional power capacitor / reactor like coordinated control, voltage fluctuation of wind farms due to compensate for Wind Power and network voltage stability.
