Determining Distribution Network Power Supply Partition Zone by Rolling-ball Model
Based on the characteristics of the power distribution network ,This paper will be equivalent to power supply partition model of distribution network and lightning protection design rolling-ball model. The boundary is determined by equaling to optional power point and lightning point; The radius is determined by equaling to transmission line model and rolling-ball method. Load point will be seen as air terminals and the zone that power supply is not guaranteed could be determined after the load power supply can meet the premise. The final power supply partition zone is defined based on the power supply guarantee rate under the different lightning flashes, and the specific location of the power supply is fixed by refining power boundary range. At last, an actual example is used to verify the validity of the method.
