| Abstract: | The reactive power compensation in the wind farm is becoming more and more attention with the rapid development of the wind power.In this paper,the reactive power loss characteristics of the wind farm are analyzed and the reactive power compensation margin of an pratical wind farm at steady-state operation is proposed.the theoretical reactive power loss of different components in the actual wind farm is presented.the reactive power loss of the wind farms under typical operating conditions is calculated.Furthermore,the total wind farm reactive power loss is obtained considering the voltage and the transformation tap.the reactive power compensation margin of the wind farm under"N-1"and"N-2"outage contingency of reactive power compensation device with the voltage and transformation ratio in the range of allowed changesis presented. |
