中文摘要

随着电力电子化电力系统规模扩大,变换器内部控制回路间的相互作用易引发谐波失稳。本文提出了一种分析方法,用于定位系统中对谐波失稳最敏感的变换器及母线,并量化其贡献度,为解决复杂电网环境下的谐波振荡问题提供理论支撑。

English Abstract

Compared with the conventional power systems, large-scale power electronics based power systems present a more complex situation, where harmonic instability may be induced by the mutual interactions between the inner control loops of the converters. This paper presents an approach to locate which power converters and buses are more sensitive and have a significant contribution to the harmonic inst...
