摘　　要：分析了交直流混合系统电压稳定性的影响因素,指出负荷特性、发电机组及其控制元件、静止无功补偿器及高压直流对电压稳定性的影响尤为突出。通过对交直流混合系统电压稳定性分析方法的研究和探讨,提出了相关的预防电压失稳措施;针对目前对电压失稳本质的认识、研究方法和理论还不够完善的情况,分析了还未解决的有关交直流电压稳定性的关键问题,并指出了今后电压失稳的研究方向和重点。Factors influencing the voltage stability of AC/DC hybrid system are analyzed. It is indicated that the load characteristic, generating unit and its control element, static reactive power compensator and high-voltage direct-current transmission exert outstanding influence on voltage stability. Upon investigation into the analysis methods of voltage stability of AC/DC hybrid system, relevant preventive measures against loss of voltage stability are proposed. In view of the deficiencies in the understanding, researching methods and theories of loss of voltage stability, the key problem unresolved about AC/DC voltage stability is analyzed; the future direction and key points of research on loss of voltage stability are also indicated.
