摘　　要：新型台区是指未来低压配电网中含有较多分布式光伏、储能、充电桩等元素,且支持柔性互联的交直流新型供电架构。为满足未来新型台区的工程化设计、研制和集成,本文基于四象限变流器设计了高效率新型台区实验平台,该平台可以根据负荷密度、负荷性质、能源禀赋的不同来构建不同的供用电拓扑结构,可模拟新型台区的负荷互济、故障转供、容灾备份、直流配电、绿电接入等优势。结合UREP实时仿真机形成闭环控制实验平台,该实验平台可作为企业研发工具,也可作为培养学生创新实践能力的实验平台。The new platform area refers to the new AC/DC power supply architecture that contains more dis-tributed photovoltaic, energy storage, charging piles and other elements in the future low-voltage distribution network, and supports flexible interconnection. In order to meet the engineering de-sign, development and integration of the new platform in the future, this paper designs a high-effi- ciency experimental platform for the new platform based on the four-quadrant converter, which can construct different power supply topologies according to different load density, load properties and energy endowments. It can simulate the advantages of load sharing, fault switching, disaster recov-ery backup, DC power distribution, and green power access of the new platform area. Combined with UREP real-time simulator, a closed-loop control experimental platform is formed, which can be used as a research and development tool for enterprises and an experimental platform for cultivat-ing students’ innovative practical ability.
