摘要
该系统采用晶闸管组替代分接头调压开关,单片机作为控制单元,通过检测系统电压和电流,确定需要接通或断开变压器调压绕组的组数和分接头开关位置,然后根据电磁能量守恒原理在对电网无冲击的时刻触发相应的晶闸管开关。使调压过程中电压波形连续无冲击,为用户提供高质量的电能。
The thyristor is used instead of tapping regulative switch and the single-chip processor is used as control unit in a control system for OLTC（On-Load Tap-Changer） . By measuring the voltage and current of power system , the group numbers of transformer winding for operation and the positions of tapping switch are obtained. According to the law of electromagnetic energy conservation the corresponding thyristors are triggered the moment no impact will be generated and the voltage waveform is continuous to supply high quality power.
