摘要
将交直流输电系统的电压稳定分析分为静态电压稳定和动态电压稳定两类,并对现有的电压稳定研究方法进行了总结,分析了各方法的优缺点。探讨了多馈入交直流系统在电压稳定方面尚待解决的问题以及未来的研究方向,认为制定适用于多馈入交直流系统的短路比指标,以及建立适合大扰动分析的系统动态模型将是下一步的研究重点。
Based on a large amount of research results home and abroad, the methods to research voltage stability in HVAC/HVDC power transmission system are reduced to static voltage stability analysis and dynamic voltage stability analysis, and the existing research methods are classified as well as the advantages and shortcomings of each method are analyzed. Especially, the problems to be solved in the research on voltage stability of multi-infeed HVAC/HVDC power transmission system and the future research direction in this field are discussed. It should be the subjects investigated in future to propose the index of short-circuit ratio suitable to multi-infeed HVAC/HVDC power transmission system and to build a dynamic power grid model suitable to large disturbance analysis.
