摘要(Abstract):

柔性直流技术是实现安全、可靠、高质量配电网的理想方案,也是对现有配电网升级改造的有效途径。以杭州大江东直流配电网示范工程为背景,详细介绍了直流配电网的RTDS(实时数字仿真器)数字仿真试验模型,包括系统整体建模、 MMC(模块化多电平换流器)阀组以及直流断路器等直流配电网关键设备的建模。介绍了仿真试验系统的连接方式,通过仿真结果说明其有效性,该系统可为直流配电网控制保护系统的产品研发、策略验证、工程出厂试验提供一个良好的检测平台。
VSC-HVDC, as an ideal plan for distribution network of security, reliability and high quality, can upgrade and renovate the existing distribution network. Under the context of Dajiangdong DC distribution network pilot project, the paper expounds RTDS(real-time digital simulator) model of VSC-based DC distribution network, including holistic modeling and modeling of MMC(modular multilevel converter) valves and DC breakers; besides, it introduces connection mode of simulation test system and verifies the effectiveness of the test method via simulation result. The RTDS simulation test system can provide a good testing platform for product research, strategy verification and factory tests of the control and protection system of VSC-based DC distribution network.
