Methods of increasing the accuracy of modeling of regimes of ultrahigh voltage transmission line according to synchronized vector measurements have been investigated. Approaches to the choice of mathematical models of calculation of regime parameters depending on accuracy of initial information are offered. The technique of modeling regimes of ultrahigh voltage air-line allowing for real characteristics of corona losses and corona reactive effect based on the air line representation by cascade circuits is offered. Modeling was performed on the example of 750 kV line. Modeling errors are investigated by different methods.
