The invention discloses a hierarchical multitask distributed calculation method of intelligent image analysis of a transformer station. The method comprises that S1) on the basis of a multi-task division method, an intelligent image analysis task is divided into multi-type tasks of different attributes; S2) execution of an algorithm of the intelligent image analysis task is divided into four hierarchies of calculation nodes, and the hierarchies execute different analysis tasks respectively; and S3) based on the divided multi-type tasks in the step S1), tasks are distributed according to the four hierarchies of calculation nodes. According to the invention, the application requirements for intelligent image analysis of the transformer station are combined fully, the problem that a lot of hardware equipment is needed when an intelligent image analysis technology is applied to the transformer station is solved, the calculating performance is improved effectively, the instantaneity of calculation is improved, and the intelligent image analysis technology can be used and popularized more widely in application of the transformer station.
