摘　　要：本文在不改变UPS高频机主电路拓扑结构和配电系统结构的前提下,提出一种利用UPS高频机的PWM整流器进行无功就地补偿控制方案,应用同步旋转坐标变换和瞬时功率理论设计控制算法,在不影响UPS有功功率的前提下,利用PWM整流器进行负载侧无功补偿,提高UPS容量利用率,改善负载侧电能质量,减小高低压配电室无功补偿容量,节省成本和占地。A control scheme of local compensation for reactive power is proposed in this paper, without changing the topology of high frequency UPS. The control algorithm is designed using synchronous rotating coordinate transformation and instantaneous power theory. Without affecting the active power of the UPS, PWM rectifier can be used for load side reactive power compensation to improve the power quality and UPS capacity utilization. It can reduce the reactive power compensation capacity of power distribution room, which results in saving cost and space.
