SENSITIVE ANALYSIS OF ENERGY CONSUMPTION OF OPERATING PARAMETERS FOR COAL-FIRED UNIT

摘要：

Due to the complexity of thermodynamic system and variability of boundary condition, the striking non-linear relationship exits between the operating parameters and the energy consumption. At present, the research of quantitatively analyzing the problem under systematic variable work conditions is lack of effective method. Based on deep research on the problem, the concept of sensitive factors of the energy consumption of operating parameters was put forward. Furthermore, by the application of analytic models to the whole thermal system under variable work conditions and adoption of the state space theory, the topological relation between the parameters of the measuring points and the energy consumption was established. Then the non-liner analysis problem on the complex thermodynamic system under multi- boundary conditions can be availably solved. With analysis to the possible work conditions of different units, curves of the sensitive factors of energy consumption of all parameters are obtained. Through utilizing the probability density functions of load distribution, the total sensitive factor of energy consumption was defined. And the sequences of all operating parameters sensitive factors of different units are obtained through calculation.
