The results show that the designed turbine output power is 10.37 MW and the total-total efficiency is 91.60%. It can operate efficiently and steadily in the range of output power from 16.2% to 155.9%. It can adapt to the variable operating conditions of solar power generation system and meet the design requirements. 1. Introduction
Printed on paper containing at least 50% wastepaper, including 10% post consumer waste. Concentrating Solar Power (CSP) utilizes solar thermal energy to drive a thermal power cycle for the generation of electricity. CSP technologies include parabolic trough, linear Fresnel, central receiver or “power tower,” and dish/engine systems.
This means the designed turbine has excellent performance with wide range of off-design operation. Therefore it can be adapted to the variable condition characteristics of solar power generation system affected by geographical distribution, seasonal variation and day-night alternation to some extent. Figure 12.
This research synthesizes the advantage of clean energy solar energy and the special physical properties of supercritical carbon dioxide, which provides a theoretical basis for the application of the S-CO2 turbine in the field of solar power generation. Solar energy is an inexhaustible source of clean energy.
The module power selected in the current design is between 5 MWe to 10MWe, so as to take advantage of S-CO2 Brayton turbine/compressor compactness. The power rating will be designed for maximum system performance, size and weight, and commercial availability for a modular solar field.
The designed turbine is subjected to three-dimensional steady aerodynamic analysis by the CFD numerical analysis software NUMECA. Next, the turbine design parameters are optimized based on numerical results and generating new designs.
