Fears abound that cogeneration plants with broken blades are going to face high electricity rates of summer peak periods. During high-rate period, the problem which managers have to consider is how to decide between immediate shutdown for repair and low-efficient operation. As the first step in this study, the optimal schedule and economic dispatch, according to abnormal condition of the steam turbine generating unit, need to be examined in detail with the gene algorithm. The problem being to consider next are the amount penalty and benefit loss, which caused by the different time rates of various seasons and the expense of the contract capacity, and the amount cost of restarting the unit when a temporary incident occurring.
Broken units should be continuously operated or rapidly shutdown to repair on the grounds that the probability of the incident is evaluated by the incident number in past years. This study is very informative for managers have to consider is how to decide between immediate shutdown for repair and low-efficient operation of cogeneration plants with broken blades.
