Problems solved by technology

[0003] At present, the analysis of thermal power plant operation optimization effect is often carried out by means of energy value analysis method and coal consumption rate of power supply. As the final index of power plant operation optimization efficiency analysis, coal consumption rate of power supply is only used to analyze and evaluate thermal power unit operation optimization efficiency through the index of coal consumption rate. As a result, it is rather one-sided to analyze the operation optimization only by using the increase of comprehensive power generation cost or the coal consumption rate of power supply. Reduce the accuracy of thermal power plant operation optimization analysis, and thus cannot play a better guiding role in thermal power plant operation optimization
