摘要:
对风电主导的微电网一次调频方法进行研究.首先,提出双馈感应式风机(DFIG)限转矩惯性控制方法,使风机能在短时内提取大量转子动能,对微电网进行频率支撑;然后,提出附加桨距角调整的补偿方法,通过桨距角变化使风机捕获更多机械功率,减少电网频率二次跌落幅度;最后,在Matlab/Simulink环境下,构建微电网模型并进行仿真.仿真结果表明:在不同的风速下,文中方法能提升微电网频率调整的动态响应能力,有效地减少电网频率二次跌落幅度.
Abstract:
Research on the primary frequency control method of microgrid dominated by wind power. Firstly, limited torque inertia control method for doubly fed induction wind turbines(DFIG)is proposed, which enables the wind turbine to extract a large amount of rotor kinetic energy in a short time to support the frequency of the microgrid. Then, compensation method for additional pitch angle adjustment is proposed by changing the pitch angle, the wind turbine can capture more mechanical power and reduce the secondary drop range of the grid frequency. Finally, in the Matlab/Simulink environment, the microgrid model is constructed and simulated. The simulation results show that under different wind speeds, the proposed methods can improve the dynamic response ability of the frequency adjustment of the microgrid, and effectively reduce the secondary drop range of the grid frequency.
