The invention discloses a method for determining an offshore wind power cluster power transmission system structure and electronic equipment. The method comprises the following steps: acquiring coordinates of a plurality of fans in an offshore wind power cluster, a center coordinate of a land centralized control center and region limitation information; based on the coordinates and the center coordinates of the multiple draught fans, candidate coordinates of the offshore boosting platform are determined; determining a first power transmission cable laying path and a target coordinate of the offshore boosting platform based on the candidate coordinates and the region limitation information; determining a second power transmission cable laying path based on the center coordinate and the target coordinate; and determining the structure of the offshore wind power cluster power transmission system based on the first power transmission cable laying path, the second power transmission cable laying path and the target coordinate. According to the method and the device, the technical problems of high power transmission cable laying cost and high operation and maintenance complexity of an offshore wind power cluster power transmission system due to the fact that site selection of an offshore boosting platform and a power transmission cable laying path are not comprehensively considered in related technologies are solved.
