Superheated Steam Temperature Control System Optimization Research In300MW Thermal Power Unit

For thermal power plant steam temperature control of the status quo, we can see most of the power plant in the case of variable conditions using manual adjustment for superheated steam temperature control to improve the level of automation of power plant production formed a bottleneck, so the superheated steam temperature control is still a major problem in the production process control system of each power plant, so many power plants in the hope that an ideal control strategy to achieve the main steam temperature control. For superheated steam temperature delay, large inertia, nonlinear, impact factors and other characteristics, the majority of scholars and researchers hot on the staff given the widespread concern of the superheated steam temperature control system, combined with advanced control principle put forward a number of new control scheme. Actual projects and improve the safe and economic operation of the control system is of great significance.In response to these circumstances, the main contents of this article are:to analyze the static characteristics of the charged object, the dynamic characteristics as well as major influencing factors, pointed out that the superheated steam temperature control of the difficulties; identification of the genetic algorithm-based object model: Internal Model Control System Design and the project put into operation.
