摘要
标幺制是电力系统短路计算中一个非常重要的概念 ,但对其概念的讲解及标幺值的归算问题历来是教学的难点。本文从基本的概念出发 ,从两个不同角度给出了标幺值的归算方法 ,并结合实例加以讲解 ,加深了学生对标幺制的理解 ,提高了学生解决实际问题的能力。
Per-unit system is a very important conception in short circuit calculation for the power system,while the introduction to the concept and the method of conversion are always the most difficult parts in the period of teaching. This paper introduces two different methods of conversion from different ways based on the fundamental concept,and then a practical example is solved by using the two methods,this could urge the students' understanding concepts and could also improve the students' ability to solve practical problems.
