| 摘要: |
| 分析了孤立中压微电网中双馈异步风力发电机组（DFIG）与动态负荷的暂态运行特性。为改善含DFIG微电网的暂态电压稳定性，提出了基于就地层储能稳定控制、DFIG快速变桨控制和甩动态负荷的暂态电压稳定协同控制策略。基于PSCAD／EMTDC建立了东澳岛中压微电网系统和稳定控制策略模型，研究结果表明，微电网暂态电压稳定性与微电网中风电渗透率和负荷特性密切相关；在大扰动下，提出的暂态电压稳定协同控制策略能有效增强微电网的电压稳定性。 |

| Abstract: |
| The transient operating characteristics of DFIG （Doubly-Fed Induction Generator） and dynamic loads are analyzed for islanded medium-voltage microgrid. A locally coordinative control strategy based on the energy storage stability control，fast wind turbine pitch angle control and dynamic load shedding is proposed to improve the transient voltage stability of microgrid with DFIG. The medium-voltage microgrid system of Dongao Island and the corresponding stability control strategy model are established based on PSCAD／EMTDC. Research results indicate that，the transient voltage stability of microgrid is closely related to the penetration rate of wind power and the load characteristic； the proposed control strategy can effectively enhance the voltage stability of microgrid under serious disturbance. |
