摘　　要：主要介绍无功控制自动原理与在变配电站的应用。为了变配电站在安装电压的无功功率控制设备后,能够提高变配电站的输电质量,使得无功功率得到一定的平衡,并且能够使VQC设备在变配电站内发挥出其最佳及输出最大的效率。首先,必须满足VQC设备的无功功率控制必须科学、可靠、安全、功能齐全;其次,VQC控制设备所得数据必须准确;同时,变配电所运行的过程中要加强设备运行管理、设备的维护,运用调压的开关与电容并联设备等方式进行无功、电压平衡,保证输电质量及功率的因数达到输配电的经济、可靠的供电。The principle of reactive power control and its application in variable power stations were introduced.In order to change the power transmission quality of the substation and the power transmission quality of the substation,so the reactive power can be balanced and the VQC equipment can be optimized in the substation.and output the maximum efficiency.The reactive power control of the VQC equipment must be scientific,reliable,safe,and complete.The data obtained by the VQC control equipment must be accurate.The equipment operation management and equipment maintenance should be strengthened during the operation of the power distribution station.Reactive power and voltage balance are carried out by using voltage-regulating switches and capacitor parallel devices to ensure that the transmission quality and power factor reach the economical and reliable power supply of transmission and distribution.
