| 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。 |

| Abstract: |
| 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. |
