Method for automatic generation of function code for simulation through visualization application program

Abstract

A method for automatic generation of a function code for simulation through a visualization application program comprises that 1) a visualization programming program based on practical engineering equipment is used, each basic pel script code is modified, so that a code generated by each pel is suitable for characteristics of a digital simulation program; 2) inner script codes of non-control protective logic function pels such as hardware resource allocation in a visualization programming program pel base are cleared, target codes are not generated any more; 3) and codes of a code generating tool in the visualization program are modified, so that the codes generated by each pel can be automatically combined to be in a function code format which can be directly called by a self-defined element in the digital simulation program. According to the method, generating efficiency of the codes for simulation is greatly improved, errors which can be brought in a process with manual work can be effectively avoided, the difference between the codes for simulation and the codes for practical equipment is lowered, and simulation validity is improved.

Description

technical field [0001] The invention belongs to the technical field of power system digital simulation, and in particular relates to a method for automatically generating function codes for simulation by a visual application program and a program using the method. Background technique [0002] Equipment related to power electronics technology in power systems, such as high-voltage direct current transmission system (HVDC), static var compensator (SVC), flexible direct current transmission system (HVDC_Light), etc., have been more and more widely used. The control and protection system logic of these power electronic devices is very complex. In order to improve the programming efficiency of control and protection programs and improve the readability of control and protection programs, these control and protection programs are no longer directly written in code forms such as C language, but using visual programming programs (such as WinTDC, Hidraw, Accel) Write it, then autom...

Problems solved by technology

[0006] The shortcomings of the current method of calling user function codes using custom components in digital simulation programs: the visual programming program is developed based on the actual engineering hardware system, and the codes of the input and output interfaces are closely related to specific hardware. There is a big difference between them; functions such as hardware configuration are no longer needed in pure program digital simulation; part of the generated code is not completely consistent with the compiler used in the digital simulation program in terms of syntax; there is no difference between the generated code files Form the function form that can be called by the user-defined components in the digital simulation program

Once the logic of the visualization application is changed, after the code is regenerated, it needs to be manually modified again to meet the requirements of the digital simulation program, which greatly reduces work efficiency
