Abstract: This paper implements a contingency selection algorithm to rank different contin-gencies. The algorithm uses the change in a performance index as a measure torank different single line outage contingencies. The shortcomings of the algorithmhave been highlighted. The main one is the masking phenomenon wherein acontingency which leaves a number of lines heavily loaded is ranked equally withone which produces single overload. It has been shown, that this masking can begreatly reduced by appropriate selection of the various parameters in the perform-ance index equation combined with experience of the system network configurationand operation. The overloads resulting from the high ranked contingencies havebeen alleviated by a passive corrective approach. This is based mainly uponcalculating a small percentage of the line distribution factors. A newly developingpower system of the central region of the Kingdom of Saudi Arabia has been usedto implement and demonstrate the effectiveness of both the ranking algorithm aswell as the passive corrective measure
