Description

technical field [0001] The invention belongs to the technical field of power system transient analysis, and in particular relates to a method for establishing a large-scale electromagnetic transient simulation example. Background technique [0002] The transient analysis of the traditional large-scale power system is carried out in the electromechanical transient stability program, because the traditional power system is mainly an AC power grid, and the operation and maintenance of the power grid mainly focuses on the fundamental frequency component of the system and the power angle stability of the system. With the development of the power system, many complex nonlinear elements appear in the system, such as new energy power generation equipment and high-voltage direct current transmission equipment. With the increasing proportion of nonlinear components in the power grid, the complexity of the transient process increases, and the traditional electromechanical transient sim...
