直驱风电并网系统小信号建模与次同步振荡特性
Small signal modeling and SSO characteristic analysis of D-PMSG grid-connected system
摘要
Abstract
This paper aims to study the subsynchronous oscillation(SSO)problem of direct-driven wind power grid-connected system through series-compensated lines.The study targeted at D-PMSG-se-ries compensation system performs a small signal system model by Matlab/Simulink,calculates the initial value of the model,and studies the influence of different parameters on SSO damping characteristics of the system by eigenvalue analysis.The results show that an SSO mode with a frequency of 40.44 Hz and a damping ratio of-0.039 exists in the direct-driven wind power-series compensation system.The SSO damping of the system increases with the increase of filter inductance and DC capacitance,and decreases with the increase of the system series complement and GSC DC voltage control parameters.关键词
