Equipment transformation programs primarily depend on the health level, operation life and other indicators of equipment. And now, it is still lacking of coordination and optimization between these transformation projects. This paper uses agglomerative clustering technology to analyze the transformation requirements. A marking index of equipment operating status and contact relationships between equipment are proposed as constraints to cluster the data of transformation. The experimental result shows that the partitions of equipment transformation divide method, which is based on distribution network topology, is better than traditional programs. It provides an effective basis for the transformation projects.
