【摘要】当前,高频UPS在数据中心的大规模应用带来了供电系统初期功率因数超前的问题,而常规电容无功补偿技术已无法解决该问题。通过对现有主流品牌UPS及典型数据中心和通信机房供电系统的测试情况进行分析,提出了采用SVG动态无功补偿技术解决数据中心供电系统的功率因数超前问题的解决方案。实验验证和现场测试结果显示,该方案解决了数据中心供电系统运行初期的功率因数超前和后期的谐波问题,进一步优化了供电质量,适用于新建数据中心采用。%Currently, high frequency UPS (Uninterruptible Power System) equipments had been used widely in data centers, which causes the problem of leading power factor of distribution system of data centers. However, Conventional capacitive reactive power compensation techniques have been unable to solve the problem. In this paper, test data of mainstream UPS , typical data center and communication centre is analysed, then, SVG as an effective scheme applied to large-scale data center,is de-veloped to solve the problem of dynamic reactive power compensation of distribution system. Experimental validation and field testing show that this scheme either corrects leading power factor of power distribution system with light loads or suppresses harmonics of overload power distribution system to further optimize the quality of
