this is the program to calculate the symmetrical fault in the three phase power system

说明：  针对Z变换法无法求取相邻采样点之间的输出响应的局限，利用MATLAB程 序语言，对单位负反馈系统的改进z变换法进行了程序设计。通过simulink仿真的实验，证 明该程序运算快速、准确，使用方便。(For the Z transform method can not strike between adjacent sampling points in response to the limitations of the output, using MATLAB programming language, a negative feedback system of units of the z transform method to improve the program design. Through simulink simulation experiments show that the procedures for computing fast, accurate and easy to use.)
