中文摘要

本文针对包含电压源换流器(VSC)和电网换流器(LCC)的混合多馈入高压直流(HMIDC)系统,提出了一种解析方法来量化系统强度对换相失败(CF)的影响。相较于传统的仿真方法,该解析模型能更高效、更深入地从理论层面揭示系统强度与换相失败之间的内在联系。

English Abstract

The strength has a large impact on the commutation failure (CF) in hybrid multi-infeed HVdc (HMIDC) systems including both voltage-source converters and line-commutated converters. However, this impact has always been quantified by the simulation-based method in earlier works, which is very time-consuming and cannot lend the exhaustively theoretical perspective. Thus, in this letter, the mathemati...
