With the consideration of most of our transformers " taps are changed manually and some fluctuate unnecessarily , this paper presents a supervision system of oltc based on plc control technique . then we combine this system with reactive power compensate device such as shunt capacitor to design a new supervision system of substation voltage and reactive power synthetic control based on plc fieldbus 针对国内变电站电压调整大多依靠人工调节,且有载调压变压器( oltc )分接头动作频繁的特点,本文提出了基于plc控制技术的有载调压监控系统的研制方法,并以此监控系统为基础,结合并联补偿电容器组等无功补偿设备,设计了一种基于plc现场总线的变电站电压无功监控系统。
