摘　　要：数据中心现有供电方案一般需经过AC/DC和DC/AC 2次变换,同时不间断电源一般需通过逆变器为负载供电,其供电可靠性和供电质量有待进一步提高,为此提出一种面向数据中心的高品质供电方案。首先给出方案的拓扑结构,在此基础上分析了方案的工作原理及数学模型,并提出一种基于电压补偿、双电源功率均衡和紧急供电的协调控制策略,在MATLAB/Simulink中对面向数据中心高品质供电方案进行了仿真验证。研究结果表明,所提方案能够很好地补偿电网电压的暂升、暂降和谐波干扰等,实现双电源功率协调分配,保障双电源停电时的不间断供电。The existing power-supply scheme for data center normally needs both AC/DC and DC/AC conversions while the uninterrupted power-supply normally needs the inverter to supply power for loads. A high-quality power-supply scheme is proposed to improve its reliability and quality. The topological structure of the proposed scheme is given,based on which ,its working principle and mathematical model are analyzed. A coordinated control strategy based on voltage compensation control, power balance between two power sources and emergency power-supply is presented and verified based on MATLAB/ Simulink. The research results show that,the proposed scheme compensates the voltage swell,voltage sag and harmonics of power grid very well,realizes the power balance between two power sources,and maintains the uninterrupted power-supply during the outage of both power sources.
