METHOD AND DEVICE FOR DETERMINING MODEL PARAMETERS FOR CONTROLLING A STEAM POWER PLANT BLOCK, CONTROL UNIT FOR A STEAM GENERATOR AND COMPUTER PROGRAM PRODUCT

摘要

The present invention relates to a method for determining or more model variables (M), and related devices of the control engineering model of the steam generator, the above method is one or more characteristics model variable control engineering model structure having for the steam generator is preset . The measurement signal of the steam generating process are recorded online. According to the invention, the one or more model parameters are estimated on-line. To this end, in the actual process (P) as well as the model steam generator is applied to the same input signal (ES). Then estimation analysis (SBA) is executed, where each of the process and / or at least one output signal of the model (ASP and / or ASM) or the one or more input signals are processed by the comparative evaluation based on the gradient analysis (SWG). The effective variable evaluation is possible estimation range is defined by an additional step in the analysis based on the inclination. If the estimate is determined as positive, and the current estimate of the one or more model parameters is improved, the model is adapted to continue using the estimates from the repeating step (SW). The invention also relates to a steam generating machine control unit, and computer program products. ;
