In recent years, there has been a growing demand for power generation from renewable energy sources. However, power generation from renewable energy sources is characterized by the fact that it is highly dependent on weather conditions, and thermal power generation requires large changes in output to adjust power. The sudden changes in temperature and strain that occur during this process have a significant impact on the remaining life of the equipment. In this study, we developed a system to identify inter...

Digital Twin for Fracture Life Expectancy Diagnosis of Thermal Power Plant Pipe

For high accuracy residual life assessments, Development of ｃｒａｃｋgrowth analysis method for the casing and Valve in the steam turbin has a lot of needs cuttting down of the repair costs and safty operating of the power station . We developed method that measuring by laser instrument , using creepcrack analysis by FEM and , and testing for a long time of crackgrowth by testpieces are mixed in the new technology. Our created method is very accuracy for result compared with ｃｒａｃｋgrowth of the service pla...
