• 要約等: It is necessary to maintain or improve the thermal efficiency in actual thermal power generation plants to reduce CO_2 emission and energy consumption. And also it is important to decrease the maintenance cost in commercial plants. Thus, when the thermal efficiency decreases, it is crucials to identify the performance deterioration factors and solve the problems promptly by sufficient energy management. However, it is difficult to understand the internal state of the plants sufficiently and to determine performance deterioration factors only from operation data because actual thermal power generation plants are composed of many components and they are very complex systems. Therefore, we develop a method based on heat and mass balance analysis to calculate the immeasurable quantity of state and the component performance in the plants, and to correct the component performance to standard state using the performence function obtained from long-term operation data. Through the method, the analysis of the influence of deterioration factors on thermal efficiency becomes possible. As the results, we can determine the main factor that affects thermal efficiency deterioration using this method.
