Method for selecting reactive power compensation location of wind power access considering system

The invention discloses a method for selecting a reactive power compensation location of a wind power access considering system, comprising the steps of: 1) real-time monitoring a local voltage stability index (L index) of each node of the wind power system through online calculation; 2) setting a threshold value L(i)G(/i), and eliminating the node with the L index less than L(i)G(/i) to obtain avoltage dangerous node; 3) calculating the sensitivity R(i)i(/i) of the reactive power of each possible reactive power compensation node to the L index of the voltage dangerous node; and 4) setting athreshold value R(i)G(/i), and eliminating the node with the R index less than R(i)G(/i) to obtain an appropriate reactive power compensation location. The invention is capable of effectively preventing voltage instability and improving the voltage stability of the wind power-containing power system. 本发明公开了种考虑风电接入的系统无功补偿地点选择方法，包括步骤：1）通过在线计算，实时监测风电系统各节点的局部电压稳定指标（指标）；2）设置个门槛值，剔除掉指标小于的节点，得到电压危险节点；3）计算各个可能的无功补偿节点的无功对电压危险节点指标的灵
