| 摘 要： | 交直流输电系统中直流换流器要消耗大量的无功功率，这使大干扰后交直流系统的暂态电压稳定性面临严峻考验。因此，研究交直流系统的暂态电压稳定性具有重要意义。文中介绍了暂态电压稳定性研究的主要内容，如暂态电压稳定性的影响因素、分析方法、稳定判据等，回顾了近20年来暂态电压稳定性问题所取得的研究成果，提出了交直流系统中预防暂态电压失稳事故的措施，并对多馈入交直流电力系统暂态电压稳定机理、负荷模型等问题进行了探讨。

| Abstract: | Converters of AC/DC power transmission systems consume lots of reactive power,which brings about great severe challenges for transient voltage stability of AC/DC power transmission systems.Therefore,the study on transient voltage stability of AC/DC power systems is of great importance.Some main research contents of transient voltage stability are presented, including the factors impacting transient voltage stability, analysis methods and stability criteria;some obtained research results in recent twenty years are reviewed;and finally the measures to prevent transient voltage instability of AC/DC power systems are proposed.Besides,the research contents of key problems of multi-infeed AC/DC power systems,such as mechanism of voltage stability and load model,are presented. |

| Keywords: | AC/DC power system transient voltage stability analysis methods influencing factors stability criteria precautionary measures |
