介绍了一种基于信号处理器多机控制系统的高压无功自动补偿装置的工作原理、软硬件设计及抗干扰措施。该装置采用晶闸管为开关投切并联电容器 ,投切控制策略为改进的“十三区图”法 ,实现了 10 k V系统无功自动补偿 ,并对电力电容器组提供了全方位保护 (过压、过流、欠压等 )
A working principle, hardware and software design and anti-interference measures of HV reactive power automatic compensation device based on signal processor multi-machine control system are introduced. The device uses a thyristor switch for switching shunt capacitors. The switching control strategy is an improved “thirteen-block diagram” method to achieve reactive power compensation of a 10 kV system and provides full protection of the power capacitor bank , Overcurrent, undervoltage, etc.)
