摘要

提出中风速区域下VSG-PMSG临界虚拟惯量参数整定方法。首先,建立VSG-PMSG模型,分析机组响应系统频率的有效动能范围。其次,构建VSG-PMSG的调频小信号模型,推导出临界虚拟惯量整定考虑因素。最后,提出适用于系统频率响应的VSG-PMSG临界虚拟惯量整定方法,并根据根轨迹图分析虚拟惯量变化对VSG-PMSG频率动态响应性能的影响规律,为多工况下调频控制参数的选择提供依据。通过Matlab/Simulink进行多工况仿真对比分析,验证理论分析的正确性。

Abstract

This paper proposes a tuning method for the critical virtual inertia parameters of VSG-PMSG in the medium wind speed region. Firstly, a VSG-PMSG model is established to analyze the effective kinetic energy range of the frequency response of the unit to system. Secondly, a frequency modulation small signal model for VSG-PMSG is constructed, and the critical virtual inertia tuning considerations are derived. Finally, a critical virtual inertia tuning method for the frequency response of VSG-PMSG to system is proposed, and the influence of virtual inertia changes on the frequency dynamic response performance of VSG-PMSG is analyzed based on the root locus, which provides a basis for the selection of frequency control parameters under multiple operating conditions. Multiple operating conditions are compared and analyzed through Matlab/Simulink simulation to verify the correctness of theoretical analysis.
