| Abstract: | According to the circuitry and transformer malfunctions in the electric power system of microcomputer protection,the article gives models of them and emulates them using MATLAB language. On the basis of kinds of the circuitry and transformer malfunctions ' analysis under different conditions, various interpolation algorithms are researched with the variable step size character of the sys- tem. Finally, achieving the main algorithm of filter and protection on transformer and distance protection, analyzing and comparing the accuracy and rapidity of the algorithm. |
