摘要
直流配电系统凭借损耗小、容量大、供电稳定性高、建设成本低和分布式电源的灵活接入等优势成为未来配电网的发展方向。文章针对贵州电网公司包含交直流微电网的柔性直流配电系统示范工程项目,介绍了直流配电系统的系统结构、关键设备以及运行控制策略。该柔性直流配电中心系统的实施,为未来直流配电网的发展提供了新思路和工程示范。
With the advantages of small loss, large capacity, high power supply stability, low construction cost and flexible access of distributed power supply, DC power distribution system has become the future development direction. This paper mainly introduces the flexible DC power distribution system with AC/DC microgrids in Guizhou power grid, including the system structure, key equipments and operation control strategy. The implementation of the flexible DC power distribution system will provide a new idea and engineering demonstration for the development of DC distribution power network in the future.
