Departure from thermal power plants currently operating difficulties around the lower production costs of power plants proposed to date cost analysis of the thermal power plant . In this paper, through the study of cost analysis methods and tools , such as index , loss analysis , data mining , combined with the characteristics of power production , fuel accounts for a large proportion of the cost of the features is proposed in accordance with the comprehensive analysis and focused analysis combined cost analysis strategies, to identify a specific method for reducing costs . A comprehensive analysis of the cost of the calculation date and the date of the cost index to determine the full range of operating conditions , from the macro analysis of changes in the cost for the operation and management decision-making , in particular, to help provide program management . This paper focuses on the specific production process , the use of data mining tools to identify the indicators of the optimization of the plant operation and loss analysis , to provide guidance for operating personnel , from the source to reduce production costs . Counter- balance method to calculate the date of coal consumption , combined with the cost of fuel , calculated daily best fuel cost and the actual cost of fuel , and control , to improve the operation and management level . Finally, on the implementation process and methods of the Japanese cost analysis system , describes how through non-traditional development tools of the the foundation business development platform , the development of fuel management , materials management , heat management system , establish a daily cost analysis model . This paper also introduces the concept of knowledge management , the informative system used information , such as test data , and the optimum operating parameters included in the scope of knowledge management .
