A method and a system for diagnosing the operating state of a transformer area

The invention relates to a method for diagnosing the operation state of a transformer area. The method comprises the following steps: S100, collecting marketing data and distribution network data fromeach service system of each transformer area; S200, preprocessing the marketing data and the distribution network data; S300, unsupervised clustering is carried out on the preprocessed marketing dataand distribution network data, and the type of each transformer area is determined; Step S400, specifying different index weights by aiming at different types of districts in combination with expertexperience, and performing comprehensive scoring on the operation of each district by adopting a classical quantitative scoring model in which an analytic hierarchy process, an entropy weight method and TOPSIS are combined; and S500, determining the operation state of each transformer area according to the operation comprehensive score of each transformer area. In addition, the invention also discloses a system for diagnosi
