新型微机控制晶闸管投切电容补偿装置

摘要

新型微机控制晶闸管投切电容补偿装置MCS-96系列单片机作为控制核心,通过晶闸管对多组电容器快速分级投切,实现了无功补偿装置的全自动优化运行。该装置特别适合于动态补偿冲击性负荷,有利于抑制电压波动和电压闪变。与同类产品相比,响应时间快小于16 ms且不需专门的放电电阻,不需限流电抗器,不需对电容预充电,结构简单,可靠性高。%In this advanced dynamic Var compensation device MCS-96 series of microprocessor is employed as control center and thyistors are used as contact less switch-to-switch capacitors rapidly. It can achieve fully automatic optimiaing operation. It is fit for the demands of dynamic Var compensation to impact load especially and is also beneficial to suppress voltage fluctuation and voltage flicker. It has faster response time <16 ms than similar type products while it need neither discharging resistance nor current limiting reactor and its capacitors need not be charged in advance. In a word the device has simpe structure and high reliability.
