针对电压暂降的问题,按照“DVR系统设计→检测算法研究→控制方法研究→系统建模→结果分析→硬件实现”的思路,利用参数模糊自整定PID控制方法,对三相无串联变压器型DVR进行控制,实现了对系统电压暂降快速、准确的补偿。(Aiming at the problem of sags, a fuzzy PID control strategy is proposed to the transformerless DVR following the idea of “DVR system→detection algorithm→control strategies→system modeling→results analysis→hardware implementing”. )
