Abstract :
Practical application of reliability analysis was made for the comparison of alternate line and bus arrangements of a future transmission substation with potential savings of up to $3.6 M. The paper describes how both the substation and the power system were simulated by using computer programs STAREL and COMREL. It presents the method used to obtain the most accurate estimates for the outage data of the system components. Finally, it expresses the results with simple reliability indices which can be meaningful for management. The results of the study show the need to include the reliability of the transmission system in a substation reliability evaluation
