摘要
忽略变流器的开关动态,提出了一种D-PMSG机组的通用平均模型建模方法,并给出了虚拟惯量控制的具体实现方法。相比详细仿真模型,D-PMSG机组的通用平均模型不仅具有与详细仿真模型一致的动态特性,同时大大提高了系统仿真速度,为风电机组多机虚拟惯量协调控制研究提供了基础。通过MATLAB/Simulink软件平台验证了所提建模方法和控制策略的有效性。
The dynamic characteristic of the switch was not taken into consideration and a method of D-PMSG generalized average model （GA model） was proposed and a detailed scheme of virtual inertia control was introduced. Compared to detailed simulation model, the proposed GA model not only has the similar dynamic characteristics, but also improved the simulation speed of the system, which lay the foundation of studying multi-machine virtual inertia control. The model of D-PMSG and the proposed control strategies had been realized with MATLAB/Simulink. The simulation results verified the validity of the model and the feasibility of the control strategies.
