含SVG的直驱风电场高频振荡分析及抑制策略
Analysis and Suppression Strategy of High Frequency Oscillation in PMSG Based Wind Farm with SVG
摘要
Abstract
High-frequency oscillations caused by the interaction between an SVG and direct-drive permanent magnet synchronous generator(PMSG)threaten the safe and stable operation of PMSG-based wind farms.To resolve this problem,a high-frequency impedance model of a PMSG-based wind farm with SVG is first established in this paper,and the formation mechanism of high frequency oscillation is analyzed.The frequency distribution of the negative damping interval of the SVG is derived,and the oscillation stability of the system is analyzed,based on which the stable value range of the system control parameters is obtained.Based on the oscillation mechanism,an additional damping control method based on current feedback is proposed in this study.The high-frequency oscillation of the wind farm is effectively suppressed by SVG high-frequency phase compensation,and the parameters are adjusted.Finally,an electromagnetic transient simulation model of a PMSG-based wind farm is developed in MATLAB/Simulink to verify the effectiveness of the oscillation analysis method and additional damping control strategy.关键词
