| Popis: | A plant-wide mass and heat balance model was fitted to 39 values of temperature, pressure and flow for a turbine cycle supplied by steam from a BWR. The calculated results were in good agreement with the measurements. For example, deviations between calculated and measured feedwater flow were usually in the order of 2 kg/s. The quality of the fitted results may be expressed as an overall assesment index Q stating directly the probability that the process is free of faults. The results are discussed with respect to the inclusion v. exclusion of the turbines' flow passing characteristics in the plant model. |
