摘要

“governor Bento Munhoz da Rocha Neto-GBM电厂”的重要性、其运行时间和运行条件使得有必要评估发电机的剩余使用寿命。还认为应当从所涉经济方面审查与它们有关的作业条件。基于H. Yoshida和K. Uemoto(1986)提出的模型以及Copel的经验,本文不仅显示了当今运行计划的消耗成本,还显示了由于启动和停止次数而导致的绝缘退化成本。它提出了一种新的操作条件,并建议了设备的绝缘测试和维护注意事项。

Valuation about remaining service life of GBM hydraulic power plant units technical and economical aspects
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.<>
