摘　　要：电压是电能主要质量指标之一。维持电力系统的电压在允许的范围内变动,对保障电力设备的正常安全运行和系统自身的安全至关重要。无功电力是影响电压质量的一个重要因素。电力系统的无功补偿与无功平衡,是保证电压质量的基本条件。本文介绍一种基于变电站通讯管理机的电压和无功自动调节装置,该装置采用逻辑表达式和可编程脚本技术分别实现调节设备闭锁和主变运行方式识别,具有极大的灵活性和适应性。Voltage is an important quality index for power systems. It is necessary to keep voltage change within an allowable range for power systems to ensure both operation safety and system safety of power equipments. Reactive power is an important factor that exerts great influence on quality of voltage. As well, reactive power compensation and reactive power balance are fundamental conditions for power systems. In this paper, a voltage and reactive power auto-adjust device is constructed which is based on communication management machine of power station. Logical expression and programming script techniques are adopted in this device to realize adjustment device closedown and recognize active execution pattern. The given device is rather flexible and adaptable.
