| 摘要: |
| 相较于交流配电网，直流配电网供电容量大、配电损耗少、拓扑结构灵活。相较于双馈风机，永磁直驱风机无需齿轮箱和电刷，损耗小、维护费用低。永磁直驱风机直流并网兼具二者优势，具有一定的市场潜力与研究价值。阐述永磁直驱风机直流并网时风机启停所面临的问题，并基于永磁同步电机(PMSM)的数学模型和常规控制策略，提出永磁风机分段控制方案，确保永磁风机的启动、入网、停机等环节的平滑过渡。在RTDS小步长(μs)模块中建立了永磁直驱风机直流并网的仿真模型，设计直驱风电系统直流并网启停控仿真算例。仿真结果表明该启停控制策略的有效性。 |

| Abstract: |
| DC distribution power network has bigger power supply capacity, fewer distribution loss and more flexible topology structures when compared to AC distribution network. Permanent magnet direct drive wind turbine can work well without the gear box and electric brush that has a lower cost and lower maintenance cost. So there has a certain market potential and research value when the PMSM running together with the DC grid connection. Based on the PMSM’ s mathematical model and the conventional control strategy, a sub-control strategy is proposed that can ensure a smooth transition during the start and stop operation for the PMSM wind turbine system. Simulation tests are built on the RTDS’ s micro second-level module, and the simulation results demonstrate that the start/stop control strategy is effective. |
