Line loss control method and system for power distribution network

The invention belongs to the technical field of power distribution network supervision, and particularly relates to a line loss control method and system for a power distribution network, and the system comprises a power distribution network control platform, a line risk identification module, a line loss evaluation module, a line optimization control module, an optimization verification module, and a remote supervision end. According to the invention, risk identification analysis is carried out on a corresponding line through the line risk identification module, and after a risk normal signal is generated, the overall loss performance condition of the corresponding line is analyzed through the line loss evaluation module. After the loss early warning signal is generated, a corresponding loss optimization strategy is determined through the line optimization control module based on the operation condition of the corresponding line, and corresponding loss optimization operation is executed according to the dete
