摘要
针对非稳态和谐波污染两个影响微机选线的关键问题,利用光线录波实验对零序暂态电流特性和利用频谱分析技术对零序电流五次谐波特性进行了研究,在此基础上提出了一种综合选线的方案。
This paper has studied the transient characteristics of the Zero sequence current using a Light beam oscillography and tne characteristics of the fifth harmonic Zero sequence current using the analyzing technology of frequency spectrum. Both the key problems,i.e. the nonsteady and harmonic pollution sources, influence seriously on the microcomputer Line-selection function. On this basis, we put forward a method of a comprehensive Line-selection function.
