摘要
多直流馈入输电系统的出现给电压稳定研究带来了全新的课题,电压失稳有可能成为这类电网安全稳定运行的最大威胁。该文就交直流并联输电系统的电压稳定问题理论、方法和对策作出机理式探讨,按照电压稳定的静态和动态分类方法分别介绍了国内外有关单馈入和多馈入直流系统电压稳定性的研究现状,评价了研究方法,展望了未来研究方向和研究重点。
The study of voltage stability about multi-infeed DC transmission systems is a new research field, so that voltage instability may probably threaten the security and stability of power grid. Some theories, methods and countermeasures of voltage stability in parallel AC/DC power systems are discussed in this paper. According to the static and dynamic classification methods for voltage stability, the research conditions of voltage stability single-infeed and multi-infeed DC power systems are introduced respectively. The research methods are evaluated, and what the research should focus on is prospected. This project is supported by National Natural Science Foundation of China(50337010) and Research Fund for the Doctoral Program of High Education(20020561004).
