摘要
采用Matlab程序设计语言和GUI界面图形对象工具实现变压器绝缘故障诊断的三维可视化输出,并改进三比值法,利用模糊数学方法构造编码隶属度函数刻画边界点的模糊区间.实例应用分析结果表明:该可视化设计技术不仅简化了传统的繁琐计算过程,提高了效率,而且故障定位准确直观,更全面地反映变压器故障信息与可能的故障原因,具有很强的实用价值.
Matlab programming language and GUI graphical interface tools are used to implement the three-dimensional visualization output for the fault diagnosis of transformer oil chromatography in this paper. In order to improve the three ratio method, the coding structure of fuzzy mathematics is also utilized to describe the membership function of fuzzy interval boundary points. The examples analysis results show that the visual design technology simplifies the complicated calculation process, improves efficiency, makes an intuitive and accurate fault location, and comprehensively reflects the transformer fault information and possible causes. It has a high practical value.
