In this paper,based on a case of urban traffic tunnel project in Zhejiang Province,the key problems in the design of DC lighting power supply and distribution in tunnel,such as voltage selection,power quality and cable cross-section selection,load classification and power supply and distribution scheme,are analyzed.The problems existing in the current tunnel DC power supply and distribution scheme are pointed out and an optimization scheme is proposed.In order to discuss with the majority of colleagues.The results can provide reference for similar projects.
