介绍了一种基于数字信号处理器(DSP)和单片机相结合的双CPU的新型无功补偿装置。以DSP负责数据采集与计算,单片机负责投切电容和外部通信。用晶闸管代替分接开关,根据系统的电压与无功功率,自动调整变压器分接头与投切电容;在对电网的无冲击时刻,触发开关,从而使得整个调节过程无冲击,又满足系统无功的需要。 A new type of reactive power compensation device based on the combination of digital signal processor (DSP) and single chip microcomputer is introduced. With DSP is responsible for data acquisition and calculation, SCM responsible for switching capacitor and external communications. Thyristor instead of tap changer, according to the system voltage and reactive power, automatically adjust the transformer tap and switching capacitor; in the absence of impact on the grid, trigger switch, so that the entire adjustment process without impact, but also to meet the system reactive power Need.
