The invention discloses a power distribution network adaptive
differential protection self-healing method based on
wireless communication, which is characterized by comprising the steps that 1, based on an intelligent distributed platform connected with a
wireless communication
system, one of a plurality of intelligent distributed terminal DTUs receives and synchronizes
differential protection data from other DTUs based on a sampling point interpolation synchronization method and an IRIG
global time synchronization method, and then the differential current in the intelligent distributed platform is detected; 2,
overcurrent switches in the platform are sequentially detected based on the differential current, and after an
overcurrent circuit breaker is detected,
tripping operation is executed on the
overcurrent circuit breaker to realize fault isolation; and 3, after fault isolation is completed, a downstream switch of the fault point transmits remote signaling to the downstream side, and an optimal load transfer scheme is selected based on
interconnection switch data and a self-healing strategy. According to the scheme, monitoring control of the operation state of the power distribution network and rapid positioning, isolation and
recovery of power distribution network faults can be achieved, the reliability is high, and the cost is low.
