Analysis of Structural Design of “Standard for Design of Solar Power Tower Plant”

Abstract

[Introduction] “Standard for Design of Solar Power Tower Plant” (GB 51307) is a comprehensive standard for solar power tower plant. The standard provides a principle for the design of related special structures. In order to understand the standard provisions and commentary completely when using “Standard for Design of Solar Power Tower Plant”, the paper aims to explain and parse the relative regulations of the structure parts of the standard. [Method] Combining with the standard stipulation, the background of standard formulation was elaborated from the aspects of general requirements, seismic design, ground and foundation, receiver tower structure and support structure of molten salt pump. The common structural types of receiver tower, foundation type of molten salt pump and foundation type of heliostat at home and abroad were introduced. The special problems such as structural control index and damping ratio of receiver tower were analyzed and discussed for engineering application. [Result] Through the introduction of the standard background and special structural types, as well as the analysis and discussion of special problems, the design and principle requirements of special structures in tower solar power plant are further understood. [Conclusion] It provides a basis for engineering application of “Standard for Design of Solar Power Tower Plant” and gives some suggestions for further research.
