Adaptive Damping Control of Near-fundamental-frequency Oscillation in Wind Power Grid-connected System
摘要
Abstract
Wind power grid-connected system has the risk of coupled near-fundamental-frequency oscillation(NFFO)induced by sudden changes in active power output when some transmission lines are out of service due to faults or maintenance procedures.Furthermore,various cut-off lines may alter the power system topology,which results in oscillation frequency variations.To address this issue,an actual suppression method based on adaptive damping control is proposed.First,the NFFO phenomenon of an actual wind farm in China is analyzed,and risk scenarios of oscillation are summarized.Then,the"instant measurement-instant identification-instant control"structure of adaptive damping control is elaborated,including the identification method of oscillation characteristics based on second-order RLC circuit equivalence and optimized design strategy of damping control parameters under all operating conditions.Finally,the suppression effect of adaptive control on oscillation modes of the target system is verified through electromagnetic transient simulation.The results show that NFFO can be suppressed quickly in diverse scenarios through the proposed adaptive control technology.关键词
