基于直流电容惯性控制的PMSG系统

PMSG System Based on DC Capacitance Inertial Control

提出了由直流环节电容实现风力机虚拟惯性支撑的控制方案。该方案最大限度地利用了直流链路电容中存储的能量,减少了由于偏离最大功率点曲线而造成的风电浪费。在Matlab/Simulink进行仿真分析,验证了模型的正确性及发电系统的稳定性与可靠性。

This paper presents a control scheme of virtual inertia support of wind turbine by dc link capacitance.This scheme maximizes the energy stored in the capacitor of the dc link and reduces the wind power waste caused by deviation from the curve of the maximum power point.Simulation analysis was carried out in Matlab/Simulink to verify the correctness of the model and the stability and reliability of the power generation system.
