摘要

电力电子装置广泛应用带来的超高次谐波问题近年来被广泛讨论

但风力发电超高次谐波发射特性的研究仍不够充分。本文选取较有代表性的双馈风机与直驱风机并网系统

分别建立其超高次谐波发射的数学模型

确定其超高次谐波频谱;采用谐波畸变率对风力发电超高次谐波主要频率分布范围及总体含量进行量化讨论;将单机系统拓展为多机风电场系统

对比研究了风电场不同风速多机组并联情况下的超高次谐波电流幅频特性。并通过PSCAD仿真验证相关结论的准确性。

Abstract

In recent years

the issue of high harmonic due to wide application of power electronic device is widely discussed

but the study for the transmission characteristic of ultra-high harmonic of wind power generation is still insufficient.In this paper

the representative double-fed fan and direct-drive fan connection system is selected to set up mathematical model of its ultra-high harmonic transmission and define its ultra-high harmonic frequency separately.The harmonic distortion rate is adopted for quantitative discussion of both main frequency distribution range and overall contents of ultra-high harmonics.The single unit wind farm unit system is extended to the multiple units wind farm system and the current amplitude characteristic of ultra-high harmonics of wind farm in case of series connection of multiple units at various wind velocities.The correctness of related conclusion is verified by the PSCAD simulation.
