摘要

为了防止电压崩溃，提出了多种电压稳定性评估方法来搜索弱母线。然而，这些评估要么只与网络拓扑有关，要么只与耗时有关。为此，本文提出并推导了考虑发电机电压调节和高压直流电压调节的电压稳定扩展电压敏感因子(EVSF)。并对一个案例进行了说明和分析。与VSF指标相比，EVSF指标对多进路高压直流弱母线的发现更为细致和灵敏。结果表明，EVSF是电力系统电压稳定分析的有效评估方法。

An improved voltage stability assessment for power system with HVDC

In order to prevent voltage collapse, lots of voltage stability assessments are proposed to search weak buses. However, these assessments are either only related to network topology or time-consumed. Therefore, voltage stability extended voltage sensitivity factor (EVSF), an improved voltage stability assessment considering voltage regulation of generator and HVDC, is given and derived in this paper. And a case is illustrated and analyzed. Comparing with VSF indicator, EVSF is more considerate and sensitive to discover weak buses with multi-infeed HVDC. It's proved that EVSF is an effectiveness assessment for power system voltage stability analysis.
