EPRI Initiatives related to Flexible Operation of High Temperature Power Plant
Variable demand and an increasing range of electricity supply methods are such that steam plant must perform under cyclic operation. Indeed, the multiplicity of generating options means that even defining a ‘typical cycle is difficult. Quantification of the range of potential damage mechanisms is even more complex. In response to the need for greater understanding of cyclic performance issues in high energy components, in 2006 EPRI initiated a series of Annual Expert Workshops on Creep Fatigue. These discussions identified key issues and areas for development related to the design and performance under transient operation. Summary documents, produced from each of the annual meetings, have helped guide this international effort in the field of creep-fatigue. It is apparent that a coordinated effort is critical to ensuring that outcomes are meaningful and effective. Excellence in science and engineering is necessary in aiding the electricity supply industry to meet current challenges associated with safe and reliable operation of plant. The present paper documents the current state of knowledge on creep fatigue behaviour and outlines achievements from the EPRI collaborative work. The overall goal of this effort is to provide the basis of a comprehensive approach to design and life management of components that are subject to creep-fatigue conditions.
