摘　　要：在总结直流输电系统常规控制策略的基础上,综合评述了近年来先进控制技术在高压直流输电HVDC(High鄄VoltageDirect鄄Currentpowertransmission)控制及调制技术中的应用研究现状,介绍了当前各种控制研究所采用的技术路线和实现方式,重点分析了各种控制方法和控制策略的优点和不足,指出了HVDC控制研究中亟待解决的问题,如控制策略的综合评估,系统化多馈入交直流系统直流调制信号选取原则,具有自适应阻尼能力的HVDC小信号调制技术,具有鲁棒性的大信号调制技术,全局协调控制等。对可能的研究手段进行了探讨。Based on the analysis of conventional HVDC (High - Voltage Direct - Current power trans-mission) control strategies,the recent application developments of advanced control technologies in HVDC controls and HVDC modulations are summarized. Studies on the designing and implementa-tion of various HVDC control strategies are introduced with their advantages and disadvantages being emphasized. The problems lying ahead in the HVDC control researches such as compre-hensive assessment of control strategies,systematic selection ways of HVDC modulation signal for multi-infeed AC / DC hybrid grid,self - adaptive HVDC small- signal modulation technique,robust big - signal modulation technique and global coordinated controls are pointed out. The potential re-search means to solve them are explored.
