摘要
随着电网规模的发展,设备和数据规模不断发展,必将导致短路电流计算的数据操作日趋繁复,并凸显传统计算模式工作量大、易出错的弊端。本文基于.NET操作平台研发了500kV变压器分支短路电流辅助计算软件,在“模型-视图-控制器”软件框架下,对变压器分支短路电流进行批量计算、结果分析。首先编辑母线名称集,设置潮流数据文件及稳定数据文件等基础数据;其次,导入数据,并调用计算程序批量计算500kV变压器中压侧、高压侧的单相及三相短路电流;再次,提取500kV母线及220kV母线的三相及单相的短路电流,并生成结果分析报告。应用效果表明,变压器分支短路电流辅助计算软件充分应用了现有计算软件和MVC架框架优势,提升了计算效率,避免了人为误差。
With the development of power grid scale,the scale of equipment and data continues to develop,which will inevitably lead to increasingly complex data manipulation for short-circuit current calculations and highlight the drawbacks of the traditional calculation model,which is heavy and error-prone.NET operating platform,the auxiliary calculation software for branch short-circuit current of 500kV transformer has been developed.The auxiliary calculation software adopts MVC framework,which can batch calculate and analyze the short-circuit current of transformer branch.Firstly,edit the bus name set and other basic data.Secondly,batch calculate the single-phase and three-phase short-circuit current of the medium voltage side and high-voltage side of the 500 kV transformer.Thirdly,output the analysis report of the results.The application results show that the transformer branch short-circuit current auxiliary calculation software fully applies the advantages of existing calculation software and the MVC frame framework to improve the calculation efficiency and avoid human errors.
