极弱电网下全功率风电机组振荡失稳机理分析与稳定控制
Oscillatory Instability Mechanism Analysis and Stabilization Control of Full-power Wind Turbine System Under Ultra-weak Grids
摘要
Abstract
To address the oscillatory instability of grid-following(GFL)-based full-power wind turbine systems under ultra-weak grid conditions,this paper visualizes the control loops of the machine-side converter(MSC)and grid-side converter(GSC)as virtual impedances composed of circuit components.From the perspective of circuit theory,the oscillatory instability mechanism of full-power wind turbine systems under ultra-weak grid conditions is revealed.On this basis,considering the limitations of existing active damping control methods,this paper proposes a reactive power hybrid synchronization control(RPHSC)approach to ensure stable operation of full-power wind turbine systems under ultra-weak grid conditions with a short-circuit rat i o(SCR)of 1.1.Meanwhile,the reactive power output by full-power wind turbine systems can be reduced.Finally,the effectiveness of the proposed method is validated through Matlab/Simulink simulation results and experimental results obtained from a hardware-in-the-loop platform using the Modeling Tech StarSim.关键词
