Abstract: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.
Keywords:HVDC power transmission  multi-infeed system  voltage stability
