| 摘要: |
| 分析了孤立微电网中双馈异步风力发电机组（DFIG）的功率电压特性，针对微电网不同运行方式约束，为改善含DFIG微电网的静态电压稳定性，提出了基于就地层储能稳定控制、DFIG快速变桨控制的静态电压稳定增强控制策略。基于PSCAD／EMTDC建立了微电网系统和稳定控制策略模型，研究结果表明，在不同运行方式下风速扰动时，提出的增强控制策略能有效增强微电网的静态电压稳定性，确保微电网的安全稳定运行。 |

| Abstract: |
| The power-voltage characteristics of DFIG（Doubly-Fed Induction Generator） with wind turbine in the isolated microgrid are analyzed and a strategy based on the local energy-storage stability control and fast pitch-angle control is proposed according to the constraints of different operating modes of microgrid with DFIG to enhance its steady-state voltage stability control. A model of microgrid system with stability control strategy is built based on PSCAD／EMTDC and the results of research indicate that，the proposed strategy enhances effectively the steady-state voltage stability of microgrid under the wind disturbances in different operating modes to guarantee its safe and stable operation. |
