Abstract :
The importance of “Governador Bento Munhoz da Rocha Neto-GBM Power Plant”, its time in service and its operating conditions render it necessary to assess the generators´ remaining service life. It was also considered appropriate to review the operating conditions relating them with the economical aspects involved. Based on a model proposed by H. Yoshida and K. Uemoto (1986) and in Copel´s experience, this paper shows not only the elapsed costs of today´s operation planner but also the cost of insulation degradation due to the number of starts and stops. It proposes a new operating condition and suggests insulation tests and maintenance precautions for equipment
