Transformer substation short-circuit current calculation system based on three-dimensional design platform and method thereof

Abstract

The invention discloses a transformer substation short-circuit current calculation system based on a three-dimensional design platform. The three-dimensional design platform comprises an electrical design module, a program setting module, and a calculation module, wherein the electrical design module can arrange electrical elements and electric connecting wires under the three-dimensional environment to finish the main wiring diagram design of the transformer substation and automatically generate an impedance chart of the main wiring diagram design of the transformer substation; the program setting module is used for defining symbols of the impedance chart, setting a short-circuit calculation point and a short-circuit current formula of the impedance chart, and setting a public calculation variable; the calculation module is used for calculating the short-circuit current of the impedance chart according to the short-circuit current formula set by the program setting module. The digitalization / three-dimensional design requirement of the transformer substation is realized based on short-circuit current calculation of the transformer substation three-dimensional design software. The conventional design mode is broken through, and the quality and efficiency of the design are effectively improved.

Description

technical field [0001] The invention belongs to the field of electrical design, and in particular relates to a substation short-circuit current calculation system based on a three-dimensional design platform and a method thereof. Background technique [0002] With the development of computer technology, three-dimensional design methods of substations began to be gradually popularized. At present, most design institutes use Bentley Substation 3D design software for substations. Other substation-related 3D design software include Bochao STD, PDMS, PDS, etc. [0003] When applying the 3D design software of substations such as Bentley Substation to carry out electrical design, the software provides drawing functions such as 2D wiring drawing, 3D equipment wire layout, and plane section drawing cutting, etc., which meets the basic 3D design requirements.

Problems solved by technology

There are some irreparable defects in the traditional two-dimensional CAD design method of substation engineering:

[0024] (1) All kinds of information are mainly entered manually, and the degree of automation is low, resulting in a large amount of repetitive work for designers, and it is easy to cause omissions

[0025] (2) A large amount of data and documents are generated in engineering design, and these information cannot be integrated, which is easy to lose and cause information islands, which affects design efficiency

[0026] (3) Lack of engineering background, short-circuit current calculation is often independent, and has no correlation with the main body of the design and subsequent processes, and cannot be directly applied to engineering design such as main wiring selection and equipment conductor selection
