Automatic modeling method for power transmission network line loss model based on CIM (common information model)

The invention discloses an automatic modeling method for a power transmission network line loss model based on CIM. The automatic modeling method comprises the following steps of analyzing, storing and converting CIM data to obtain data of the power transmission network line loss model; performing automatic layout and automatic wire connection according to endpoint information and connection point information in the data of the model; automatically generating a power transmission network wire connecting graph; correlating the model and the graph; and performing automatic modeling on the power transmission network line loss model. The automatic modeling method for the power transmission network line loss model based on the CIM model can overcome shortcomings that in the prior art, workload is high, accuracy is low, promptness is also low and the like, and has the advantages of low workload, high accuracy and high promptness.
