Checking power plant components in a more targeted manner
This enables operators and monitoring institutions to calculate the stability of components in terms of their damage more accurately and without compromising on safety.
Adjusting inspections to the actual load
Until now, conventional power plants were designed for full-load operation with constant pressure and temperature conditions. However, if in future it is intended that they should only produce the electricity requirement not covered by renewables, this will require a new, flexible mode of operation.
For all components, this means more part loads, more start-up and shut-down cycles, and more extreme and rapid temperature changes. Scientists have therefore studied the loads on thick-walled power plant components under cyclic temperature changes.
They have developed and tested a new method for conducting fracture mechanics-based analyses of the damage tolerance. The findings were also incorporated into a draft guideline for the fracture mechanics-based concept, which is currently in the validation phase.
The results are important for the business calculations made by power plant operators because the more frequent partial load operation causes not only higher maintenance costs but also reduced revenue from electricity sales than under full-load operation. TÜV Nord carried out the research project together with the University of Rostock and Research Centre Jülich.
