the optimal configuration of section switches requires the nonlinear integer programming and the technology, reliability and economy should be taken into account. Therefore, this paper put forward a planning method to determine the optimal additional number and installation position of section switches, which is based on the original frame and switches and combined with the drawing functions in the digital system of the distribution network wiring diagram. The objective function of this method considers the annual investment cost of section switches, the annual operation maintenance cost and the annual loss in outage. It also gives consideration to the correction of investment constraints on the jurisdiction index interval to calculate the number of required additional section switches. Finally, the digital system of the distribution network wiring diagram is utilized to simulate the actual configuration of switches, and the configuration of section switches is optimized by simulating faults through disconnecting the power supply.
