Method for performing fault recovery on power distribution network based on ultra-short term load

The invention discloses a method for performing fault recovery on a power distribution network based on ultra-short term load. The method comprises the following steps: predicting the load condition of the power distribution network in a future period by adopting an ultra-short term load prediction technology, wherein the maximum load occurring in the period is taken as calculated load; constructing a calculated load database by using the calculated load of each load node of the power distribution network; performing a fault recovery algorithm based on the calculated load database to obtain a fault recovery switching operation result. According to the method, the defects that certain electrical elements are overloaded, an outlet circuit breaker is tripped out or potential safety hazard occurs in non-fault elements and the power supply quality is influenced strictly since the conventional fault recovery method for the power distribution network cannot adapt to the load change in a time period from isolation of a field fault area to the removal of faults are overcome.
