摘　　要：维持电力系统的电压在允许的范围内变动,对保障电力负荷的正常运行和系统自身的安全至关重要,而电压水平则是与无功功率的平衡密切相关,控制无功补偿的电容器投切,可以改变无功功率分布,改善功率因素,减少网损和电压损耗,分析了以工控机为载体的电压和无功自动调节装置。To protect the normal load operation and the safety of its system, it＇s essential to maintain the power system voltage variation within allowable range. However the voltage level is closely related to the balance of the reactive power. To control the reactive power compensation, the capacitor switching can change the distribution of reactive power, improve power factor, and reduce network loss and voltage＇, loss. This paper analyzes the voltage and reactive power automatic regulation device based on industrial control computer.
