216 モデルベース監視による熱交換プロセスの性能低下検出

抄録

The on-line performance monitoring of a heat exchanging process using water and steam, which is one of the key components of distributed energy supply system, has been develop on the basis of a theoretical model. By using an input-output model of the process, this performance monitoring first estimates output process variables and heat exchange performance of the process in response to the variation in measured input process variables. These estimated values are then compared with the measured ones for the on-line performance monitoring. Its effectiveness under transient state has been confirmed by the numerical analysis. The result confirmed the sufficiency of the estimation accuracy of the output process variables and heat exchange performance under transient state and the detection capability of the deterioration of the heat exchange performance.
