摘要： 重点分析长距离电缆对谐波适应性测试的影响,以空载条件为基准提出基于电缆分布参数模型的海上风电机组谐波适应性远端检测方法。在双馈风机并网负载条件下,分别比较不同电缆长度和电容参数对风机谐振特性的影响。提出风机和风电场层面复合滤波的方法通过在风电机组逆变侧设计并配置LCL有源阻尼滤波器抑制高次谐波,并在公共连接点安装新型C型滤波器,为系统提供无功补偿的同时,消除谐振谐波,有效避免谐振。最后利用Simulink仿真,通过配置滤波器前后的谐波对比验证了所提方法的有效性。

Abstract: The influence of long distance cable on harmonic adaptability test was analyzed, and the method for remote test on harmonic adaptability of offshore wind turbine was proposed in no-load condition based on the cable distribution parameter model. Based on double-fed induction generator(DFIG)system with load connected, the influences of different cable lengths and capacitance parameters on the resonant characteristics were compared. Wind turbine and wind farm composite filtering method was proposed. LCL active filter was designed to eliminate the high frequency harmonics of DFIG rectifier, and C-type filter at the point of common coupling(PCC)was applied to mitigate resonant harmonic, to provide reactive power as well. The simulation module was built in Simulink, and the proposed method was verified by the comparison of the harmonic without and with the designed filters.

Key words: offshore wind turbine, resonance, remote testing of harmonic adaptability, cable, C-type filter, LCL active filter
