Research On Model Analysis And Application Of Ultra-supercritical Unit Steam Generator

To develop the ultra-supercritical power unit is an efficient way to solve the power source problems of our country by means of its high efficiency, environment protection and so on. Research on the ultra-supercritical unit characteristics of working and running deeply in order to provide the basis of cooperative control is a key issue technology in ultra-supercritical unit development. This article studies ultra-supercritical unit steaming zone statistic and dynamic characteristics and the variety of the fuel/feed ratio following with the load, establishing the steam generator dynamic model and fix the parameters by system identification, and discuss the use of storage heat in the real cooperative control.
