Embodiment Construction

[0051] The technical solutions and technical effects of the present invention will be further described in detail below in conjunction with the accompanying drawings of the present invention.

[0052] Please see figure 1 , in a specific implementation manner, a method for establishing a large-scale electromagnetic transient simulation example includes the following steps:

[0053] S10. Obtain an electromechanical transient simulation example.

[0054]The traditional power system is mainly an AC power grid. The operation and maintenance of the power grid mainly focuses on the fundamental frequency component of the system and the stability of the power angle of the system, so the electromechanical transient simulation example is used. However, with the increasing complexity of the power system and the increasing number of complex nonlinear components in the system, the complexity of the transient process increases, and the traditional electromechanical transient simulation prog...

Abstract

The invention provides a method for establishing a large-scale electromagnetic transient simulation example, and belongs to the technical field of power system transient analysis. The method comprisesthe following steps: obtaining an electromechanical transient simulation example; converting the electromechanical transient simulation example into a preliminary electromagnetic transient simulationexample; obtaining key parameters from the preliminary electromagnetic transient simulation example; and correcting the key parameters to obtain an electromagnetic transient simulation example. An electromechanical transient simulation example is converted into a preliminary electromagnetic transient simulation example, key parameters are obtained from the preliminary electromagnetic transient simulation example, the key parameters are corrected, and the electromagnetic transient simulation example is obtained. The key parameters in the preliminary electromagnetic transient simulation exampleare corrected, so that the electromagnetic transient simulation example is automatically generated, and the integrity and accuracy of the parameters of the electromagnetic transient simulation example are ensured.

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...
