摘要
介绍了小型变配电站电压无功调节自动控制系统的组成、控制方法与控制原理。该系统以超小型可编程逻辑控制器LOGO!230RCL为核心,可在负荷变化引起电压波动时自动控制电力变压器和无功功率补偿器的投入与切换,实现无功平衡和调节电压的目的。运行结果表明,自控系统控制可靠、运行稳定、操作方便。
This article introduces small-transformer substation on voltage non-work regulation automatic control system constituent and control method and control principal.The core of the system consists of the small-PLC. When the load change induces voltage pulsation,the system can auto-control power transformer and non-work power compensator throw-in and throw-over in order to realize relative balance and voltage-adjusting.Result indicates that the system has reliability and running stability and operating convenience.
