Abstract

Rapid increase of the transmission capacity and environmental limit of the power transmission passage have indispensably promoted development of the AC/DC hybrid transmission lines on the same tower, especially for UHV systems being established in China. Unfortunately, severe electromagnetic coupling effects will inevitably exist between the UHV AC and DC transmission lines built on the same tower. The generating mechanisms, as well as the computational methodology, of both the inductive and capacitive coupling effects within the hybrid transmission lines are elucidated in the paper, then an equivalent circuitry model is established as to analyze the induced overvoltage within the hybrid transmission lines under different fault conditions. Further, the impacts on the induced overvoltage on the healthy line from key influential factors, such as the grounding fault resistance, the collocation and layout of DC filters and fault type, are accounted for in details. Specifically, phase-mode transform method is adopted to theoretically analyze the effect of transposition mode of the UHV AC transmission line as how to reduce the induced overvoltage within the hybrid transmission lines. The proposed method and analyzed results present reliable reference for realizing optimal design of the UHV AC/DC hybrid transmission lines.
