【摘要】 研究了所使用的过零比较、软锁相(SoftPhaseLockedLoop,简称SPLL)、最小二乘法等多种锁相技术和同相位补偿和非同相位补偿的DVR控制策略,比较分析了其各自的原理和特点。通过实验验证了所提出的锁相技术和控制策略。更多还原

【Abstract】 Several phase locked techniques used in dynamic voltage restorer, such as Zero-Crossing,Soft Phase Locked Loop, Least-squares estimation,are compared and analyzed. Thereafter, the DVR control strategies,the same phase compensation and the different phase compensation are studied in detail. Experiment results are presented.更多还原
