| Abstract: | This paper introduces the concept of fuzzy set theory into the discrimination between faults and power swings. By means of abstracting the proper characteristic parameters and endowing them with the proper weights, we can easily make comprehensive estimation on the three conditions: faults, swings and faults in swings. It is obvious that this method is highly effective from the result of much simulation. |

| Keywords: | fuzzy set theory relative membership faults and power swings simulations |
