Embodiment Construction

[0017] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0018] In order to better understand the illustrative embodiments of the present invention, the main idea of ​​the illustrative embodiments of the present invention is briefly described below.

[0019] For computer simulation, traditional software development is modeled from the perspective of algorithms. However, software written in this way is not easy to maintain, and the system robustness is not high. The object-oriented method holds that: the problems of the objective world are composed of the entities of the objective world and t...

Abstract

The invention discloses an object oriented technology-based direct current system modeling method and an object oriented technology-based direct current system fault simulation method. The modeling method comprises the steps of analyzing each function model of a primary direct-current transmission system and a control system of the primary direct-current transmission system, and calling a basic model constituting each function module and a calculating module of each basic module. Due to the adoption of the object oriented technology, the correlation degree between modules is effectively reduced, and then mutual influence between programmers is reduced. In the initial stage of design, the basic model to function model to integrated system layer-by-layer encapsulation inheritance mode is adopted in an object system on the premise that only a small number of programmers are involved, and then cost caused by correction in the future is reduced greatly and the robustness of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of power system simulation, in particular to a DC system modeling method and a fault simulation method based on object-oriented technology. Background technique [0002] The eastern region of my country is economically developed, and the electricity load is relatively concentrated, but energy is relatively scarce. In recent years, with the construction of large-scale new energy in Northwest my country, there will be a large amount of clean energy such as wind power and solar energy in the west that needs to be transported to the east over long distances. The use of high voltage direct current (HVDC) can effectively save line corridors, help improve the network structure, reduce transmission bottlenecks, and achieve a wide range of optimal allocation of resources, with obvious economic and social benefits. At the same time, it is also of great significance to improve the independent innovation and manufactur...
