Research Of Structural Theory And Its Application In Malfunction Diagnosis Of The Thermal System

The paper studies structural theory of thermoeconomics and its application for the malfunction diagnosis in details. The computation and analysis associating with structural theory are proceeded with a satisfying result. The research has been emphasized on the followings:1. Models of thermoeconomics related with structural theory are summarized with illuminating the general foundation of structural theory.2. The system of structural theory is summarized, and some specific problems are studied.3. A complex energy system with structural theory is to be discussed in detail, and the exergy cost of its unit product is calculated.4. Malfunction and its impact are to be analyzed by using the method of structural theory, and resulted in a formulation of malfunction diagnosis, and a simulated malfunction of the complex energy system is tried to Diagnose.5. A related optimization criterion is searched by applying the optimization technique based on structural theory.6. A computer program of structural theory and its relevant application are developed by using Delphi and database technique. And a modular of the thermoeconomics online monitoring is worked out.
