Distributing line planning and distribution transform site selection optimizing method based on load moment theory

Disclosed is a distributing line planning and distribution transform site selection optimizing method based on the load moment theory. The method is used for providing detection and analysis for line transformation such as line diameter change or load cutting and providing optimum load point distributing calculation and line specification model selection for an added plan based on known actual or future loads of a line by means of load moment calculation of the line loads during powerline transformation or added plan implementation. To solve the technical problems, the distributing line detection and power supply point distributing method takes county-level electric power enterprises as planning targets, the health degree of the line is calculated through a power grid model, and shunt lines are divided. Compared with the prior art, the distributing line planning and distribution transform site selection optimizing method based on the load moment theory has the advantages that load shunting is carried out on lines with low health degree through load moment calculation by means of the current power grid model, and powerline design or old line transformation is achieved based on an optimal economical-efficiency design with as little change as possible.
