Using REx environment in dynamic diagnostics of ORC power station

In the Institute of Fundamentals of Machinery Design is developed a development environment REx, which is dedicated for designing and testing diagnostic expert systems for complex technical objects. The REx environment allows to design, test and use a multilayer statement networks. Paper presents an example of using REx environment for diagnose state of some objects of ORC power station. Results of the inference process of the expert system that are very interesting for the operator are presented in a special application. In this application are presented values of statements and how there are changed during the time.
