摘要

针对传统的同步发电机缓慢运行可能会影响微网系统稳定的问题,研究虚拟惯性控制方法在双馈异步电机风力发电机中的应用。首先详细介绍引入虚拟惯性的2种控制方法及其数学模型,然后通过构建小信号模型研究所提出的控制方法对于孤岛模式下微网系统稳定性的影响,比较使用双馈风电机组旋转质量或超级电容器作为虚拟惯性源的优缺点以及风速变化的对于系统稳定性的影响。最后,基于Matlab/Simulink建立仿真模型,仿真结果证明,引入虚拟惯性可显著增加系统稳定性,但基于旋转质量虚拟惯性控制效果受风力发电机转速影响较大,基于超级电容器的虚拟惯性控制效果最佳。

Abstract

Aiming at the problem that the slow operation of traditional synchronous generator may affect the stability of microgrid system, the application of virtual inertia control method in doubly fed induction motor wind turbine is studied. Firstly, two control methods and their mathematical models introducing virtual inertia are introduced in detail. Then, by constructing a small signal model, the influence of the proposed control method on the stability of microgrid system in island mode is studied. The advantages and disadvantages of using doubly fed wind turbine rotating mass or super capacitor as virtual inertia source and the influence of wind speed change on system stability are compared. Finally, the simulation model is established based on Matlab/Simulink. The simulation results show that the introduction of virtual inertia can significantly increase the system stability, but the effect of virtual inertia control based on rotating mass is greatly affected by fan speed, and the effect of virtual inertia control based on supercapacitor is the best.
