The maintenance of power system equipment and generating units is implicitly related to power system reliability and has a tremendous hearing on the operation of the power system. Therefore, the maintenance problem has always been investigated together with system reliability problems. The maintenance schedules of power generating units attracts great attention in both planning and designing power systems and also in operation management. The scheduled maintenance should he periodically arranged and effectively organized repair work should be carried out after a random fault has occurred. The general aim of these activities is to ensure that equipment is always in or is restored to sound operating condition. In addition, this is expected to reduce equipment faults, to extend the equipment life, and to increase the reliability and economic benefits of power system. As a result it costs the electricity utilities ii great deal of money every year to carry out this work.
