【摘要】 针对当前三相不平衡所造成的危害,建立三相四线制接线形式下的不平衡无功补偿模型,设计基于主控芯片Freescale 56F807的补偿控制器,采集数据,对不平衡情况进行补偿,结果表明,该补偿控制器可以使三相不平衡情况得到有效的改善,依据相应的补偿控制策略,获得较好的电能质量,并且达到较好的节电效果。更多还原

【Abstract】 In view of the harm that caused by the three-phase unbalanced load current,based on the algorithm of compensation of 3-phase 4-wire unbalanced load current system,this paper establishes compensation controller based on Freescale 56F807,collects real-time data and compensates the situation of unbalanced load current. The results show that the compensation controller makes three-phase unbalanced load current effectively improved,according to the corresponding compensation strategy,a better power quality and energy-saving obtained.更多还原
