Small and medium size drum boiler models suitable for long term dynamic response

Data and control schemes for small and medium size drum boiler models are presented. Methods and field tests for the data evaluation are included. Simulation of the model response against megawatt response field tests are also included. The resulting errors due to measurement inaccuracies and model simplification, and the applied procedure for data evaluation are also presented. The size of the boilers partially solved the data problem which limited the applicability of the low-order models (LOMs). The LOM parameter and associated standard deviation obtained via the plant probes depict the variable conditions with which the controller is faced. The obtained data are useful for controller synthesis and tuning, especially for control logics which utilize a simplified boiler model as part of their control law.<
