Abstract
The optimization target system of a 300MW circulating fluidized bed coal-fired unit was established by using the method of K-Means clustering algorithm to determine the variable condition calculated benchmark value point. This method was proved to be effective, and the results supply a new idea and effective method for determining benchmark values models. The off-design load characteristics of consumption-deviation coefficient mainly have three trends, and the condenser vacuum, relative internal efficiency of steam turbine and oxygen content in exhaust gas were the primary influencing parameters of energy-loss analysis. Through energy-loss analysis method, providing an accurate and effective guidance for the management and saving energy, and it has a good economic advantages and promoting significance.
