Analysis of Steam Temperature Control System of Fengcheng Power Plant 300 MW Unit
Abstract
The importance, task as well as its composition of temperature control system of the thermal power plant, static characteristics and dynamic characteristics of main steam temperature process were introduced systematically by the author. In light of the large delay,strong inertia of steam temperature process, many kinds of control methods used in stream temperature control were presented.On the base of the contents introduced above, take the Fengcheng power plant as the example, the author analyzed its steam temperature control system. In order to verify the correction of analysis, with the permit of the lab conditions, the author finished the relevant control system configurations in the ABB's Symphony environment.
