Abstract: According to the construction direction of the new power system, which is safe and controllable, flexible and efficient, Ningbo Power Supply Company puts forward the remote programmatic operation + state transfer mode of power network maintenance work. In this mode, the remote programmed operation of the control terminal completes the equipment disservice to the "handover state", and the subsequent operation and maintenance personnel give the order to operate to the "working state" and authorize the work according to the safety requirements and the separation and optimization scheme of the primary and secondary operations of the equipment. Through practical comparison, under the premise of controllable security risks, the new mode greatly shortens the operation time of power outage, improves the utilization rate of equipment and the operation efficiency of power grid, and has obvious economic and social benefits, which is worthy of comprehensive promotion.
