For solving many problems in rapid city development of traditional 220 kV/1 1 0 kV/1 0 kV voltage reduction mode,internationally used 20 kV power distribution voltage class was introduced in Shenzhen power grid. Combining with local practice,power supply mode of 220 kV dropping straight 20 kV was used for trial point and development mode for pri-ority selection for city power grid was explored. Idea,method and application practice of constructing 500 kV/220 kV/20 kV/0.4 kV voltage sequence system in Guangming new area in Shenzhen was described and several key problems were stated one by one which might provide reference opinions and suggestions for developing this work.
