摘　　要：根据当下无功功率和谐波引起的电网质量下降及接触器投切补偿电容器的不足所研制的新型晶闸管投切电容器TSC动态无功补偿装置。从无功补偿的原理出发,建立了电容器的自动补偿最佳控制方法,并采用晶闸管无触点开关实现快速自动投切,它是通过检测晶闸管无触点开关两端电压为零来做触发的必要条件,这样使整个系统有着硬件闭锁保护,从而有效地避免了误触发给系统造成的冲击电流而损坏元件,同时不会产生无功倒送。According to the decline of power grid quality and the inadequate of switching compensation ca- pacitor caused by reactive power and harmonics, a new thyristor capacitor TSC dynamic reactive power compensation device is manufactured. Reactive power compensation in principle, to establish the optimal control method for automatic compensation capacitor, and using non-contact switch thyristor fast automat- ic switching, which is non-contact switch by detecting the voltage across the thyristor zero to do trigger necessary conditions, so that the whole system has a hardware lockout protection, thus effectively avoiding inadvertently distributed system damage caused by the impact of the current element, but does not produce reactive power to send down.
