智能化变电所一次回路CAD系统软件开发

Development of intelligent CAD system software for primary circuit in transformer substations

针对目前多数电力系统的计算机辅助设计(CAD)应用软件仅仅具有辅助绘图功能,而缺少辅助设计功能的情况,开发了采用专家系统支持的智能化技术的变电所一次回路CAD系统软件,将各种计算、设计、绘图规则编成知识条文写入计算模块和规则库中,采用数组、结构体、集合类和数据库组织管理数据,利用ActiveX技术二次开发AutoCAD,最终实现变电所一次回路的智能设计与自动绘图一体化。

At present, most computer-aided design （CAD） applications for power system do not have computer-aided design function, but only computer-aided drawing capability. As a result, CAD system software for primary circuit in transformer substations has been developed with intelligent technique supported by expert system. Calculation, design and drawing rules are put as knowledge lists into calculation modules and rule base~ arrays, structures, classes and database are used to organize and manage data in the program, and ActiveX technique is adopted to redevelop AutoCAD, which realizes the integration of intelligent design and automatic drawing for the primary circuit in transformer substations.
