The invention discloses a district transformer economic switching scheduling method. The method is characterized by comprising the following steps: step 1, reading district transformer parameters and parallel modes; step 2, according to load prediction, obtaining a peak load; step 3, calculating an available mode of the peak load; step 4, forming an available sequence set; step 5, forming a frequency optimization sequence set; step 6, applying optimal path selection to select an optimal sequence; step 7, according to the load prediction, updating peak loads in the following two days in a rolling mode; and step 8, examining the safety of a corresponding two-day combination mode in the economic optimal sequence in a rolling mode by use of updated peak loads of the following two days. The method provided by the invention can simultaneously arrange district transformer switching time of the following seven days and corresponding combination modes, realizes economic switching scheduling of a district transformer, can satisfy safe operation of the transformer, at the same time controls the transformer switching frequency and density, and accords with the scheduling operation practice of a district transformer station.
