Embodiment 1
[0090] like figure 1 As shown, the invention of this example is applicable to the reactive power control system for the voltage control of the grid connection point of the wind farm. The system includes a dispatching system, and the dispatching system is connected to the automatic voltage control (AVC) system of the wind farm. The automatic voltage control of the wind farm The system is respectively connected with the reactive power reference given improved wind farm concentrated reactive power compensation device (SVC), measurement device and wind turbine data acquisition and supervisory control (SCADA) system; the wind turbine data acquisition and supervisory control (SCADA) system and wind power Fans with reactive power regulation capability in the field are connected. The wind farm AVC system communicates and issues commands with the dispatching system, the measuring device, the wind turbine SCADA system and the wind farm concentrated reactive power compensation device (SV...
