    Abstract
  • The frequent changes of coal calorific value seriously affect the characteristics and efficiency of direct air-cooling unit. Source instability of coal in thermal power plant and difficulty in getting the actual calorific value of coal real-time and accuracy brings great difficulties for the design of unit coordinated control system.Therefore, A model-based fuel BTU correction method for direct air-cooling unit. is studied. The ratio between the actual value of the unit load and the forecast load of the unit model is used to reflect the relationship between the calorific value of the actual coal and design of calorific value of coal. Therefore, the fuel quantity entering the boiler is corrected in real time and the influence of coal calorific value variation on the unit coordinated control system is eliminated. Through simulation experiment and actual data validation, the coordination control system has good control quality in the case of frequent coal calorific value fluctuation and there is no effect when coal calorific value is stable. What's more, the obtained BTU correction coefficient is not affected by the input signal of model, which can accurately reflect the actual coal calorific value changes in real time. This method is feasible and effective and it can be adapted to the frequent changes of coal quality in the field.
