基于AutoCAD二次开发技术的光伏专用电缆敷设插件的应用OA

Considering that there is currently no efficient and accurate design method for PV cable laying design work in PV power generation projects,most design units still use manual drawing or proportional estimation methods.Based on this,this paper has developed a set of plug-in based on AutoCAD secondary development technology that can assist in the design work of PV cable laying in PV power generation projects——PV cable laying plug-in.Firstly,taking the PV cable laying of a certain actual PV power generation project as an example,the functional design and implementation of the plug-in are introduced.Then,the operating interfaces of each function are explained.Finally,the commonly used methods for PV cable laying design and the PV cable laying plug-in will be compared in terms of their design effectiveness.The research results show that the design time of manual drawing method is the highest,and the accuracy of statistical results is poor.The proportion estimation method is inferior to the design effect of PV cable laying plug-in in terms of both statistical accuracy and completeness of results.The PV cable laying plug-in has performed well in design time,completeness of results,and the difference between the designed cable length and the actual cable length used,making it the optimal design method.The application of this research result can reduce the design difficulty of PV cable laying,improve the efficiency of drawing,and reduce the difficulty of construction.
