电压无功控制设备对系统电压的影响分析

Analysis on the Influences of Voltage Reactive Control Equipment on System Voltage

控制设备的合理选择是进行电压无功控制的关键。以两端网络输入阻抗作为节点之间的电气距离,提出通过电气距离来衡量电压无功控制设备的影响能力。以IEEE30节点算例为对象,分析了控制设备对节点电压的灵敏度,找出了控制设备之间的相互关系。

The reasonable choice of control equipments is the key of voltage reactive control.Taking the network input impedance of both ends as the electrical distance between nodes,this paper points out that the electrical distance can be used to measure the influence ability of voltage reactive control equipment,and taking the IEEE30-node example as the object,analyzes the sensitivity of control equipment on node voltage,and finds out the interrelation among control equipment.
