The invention discloses a high voltage distribution network optimizing and scheduling method. The method is characterized in that with the comprehensive optimization of the power supply capacity, the circuit establishment and the partition and contact mode as the target, a two-stage high voltage distribution network optimizing and scheduling model is established. The method is used for scheduling the 220 kV power supply point position and capacity, scheduling circuits with voltage of 110 kV or lower and comprehensively optimizing the load optimizing partition and contact scheme.
