摘　　要：渝鄂柔性直流背靠背工程是世界首个用于异步大型电网互联的柔性直流工程。为了对该工程阀基控制设备进行技术研究与出厂测试,研究MMC拓扑及其控制原理,依据渝鄂工程特点进行了阀基控制设备的软硬件设计,搭建了阀基控制设备全规模接入的动态模拟系统,并提出了全面的控制设备试验项目及试验方法。通过测试结果与渝鄂工程现场数据的对比,证明所搭建动态模拟系统的相似性和等效性。该测试平台已在渝鄂柔性直流输电工程阀基控制设备出厂试验中应用,也可为其他柔性直流输电工程控制设备的试验提供借鉴。Yu-E back-to-back flexible HVDC project is the first flexible HVDC project for asynchronous large-scale power grid interconnection in the world. In order to carry out technical research and rigorous factory testing of the valve-based control equipment for this project, this paper studies the MMC topology and its control principle. According to the characteristics of the Yu-E project, the paper designs the software and hardware of the valve-based control equipment, establishes a full-scale accessing dynamic simulation system and proposes the comprehensive control equipment test items and test methods. By comparing the test results and the on-site data of Yu-E project, it proves similarity and equivalence of the built dynamic simulation system. The test platform has been applied in the factory test of the control equipment of the Yu-E flexible HVDC project, and can also provide references for the test of the control equipment of other flexible HVDC projects.
