Embodiment Construction

[0026] Below in conjunction with embodiment the present invention is described in further detail:

[0027] 1. Calculation method of submarine cable ampacity based on mixed programming of C# and COMSOL, such as figure 1 shown, including the following steps:

[0028] a. Establish a cable model in COMSOL and generate a .m file in the form of a function;

[0029] The specific operation is to set the appropriate physical field in COMSOL, define constants, variables and geometric models, set material parameters, physical quantity parameters, boundary conditions and initial values, define the finite element mesh division principle, and apply the COMSOL solver to solve and obtain results Visualize, generate .m files in functional form, and parameterize them.

[0030] Specifically, the physical field mainly includes power plants, magnetic fields, temperature fields, etc. The defined constants are the mechanical parameters that define the cables (see Table 1, including all parameters)...

Abstract

The invention discloses a submarine cable ampacity calculation method based on mixed programming of C# and COMSOL, which belongs to the field of electric power systems, and comprises the following steps: a, establish a cable model in COMSOL, and generate a .m file in the form of a function; b, activate MATLAB; c , to pass commands and parameters to MATLAB, and execute the .m file; d, to call the COMSOL command to write the result to the TXT file; e, to display the cloud map of the temperature field on the C# result interface. The technical problem to be solved in the present invention is to provide a submarine cable ampacity calculation method based on C# and COMSOL mixed programming, which realizes the seamless connection between C# and COMSOL, and reduces the user's learning cost for calculating cable ampacity by finite element method And use cost, reduce the burden of professional designers, greatly improve production efficiency.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for calculating the ampacity of cables. Background technique [0002] With the rapid development of offshore wind power, offshore wind power will become an important part of wind power generation, and submarine cables are an important connection hub between onshore power grids and offshore wind farms. The long-term allowable current of the cable should meet the requirements of the continuous working current. The selected cable is modeled and simulated through COMSOL to obtain the current carrying capacity of the cable of this type. [0003] COMSOL is a large-scale advanced numerical simulation software that is widely used in scientific research and engineering calculations in various fields to simulate various physical processes in the fields of science and engineering. However, due to the strong professionalism of COMSOL, it is difficult for ordinary engineering designers ...
