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。
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 mierogrid 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.
