The invention discloses a distribution
network overhead line fault self-healing method,
system and device and a medium, and belongs to the technical field of power
system fault self-healing, and the method comprises the steps: laying a synchronous
phasor measurement unit, and generating a unified
phasor reference through cloud edge cooperative calculation; the edge coordination engine calculates the load flow change after
loop closing by means of a unified
phasor reference and an instantaneous topological state to form an action sequence; the local controller obtains a coordination coefficient and controls the pre-compensation of the flexible
interconnection device and the closing time of the section switch; pushing the temperature rise prediction value to a wire
thermal model; and the edge controller circularly and adaptively corrects the compensation parameter of the flexible
interconnection device, and writes the event into the self-healing
knowledge base. According to the invention,
automation and intelligentization of fault self-healing are realized, the efficiency of fault self-healing is significantly improved, and long-term stable operation of the power distribution network after fault
recovery is ensured; and through intelligent and
adaptive design, a brand new technical path is provided for long-term reliable operation of the distribution network.
