| The research is a part of scientific and technological innovation incentive funds in Inner Mongolia Region. The turbine in solar chimney power plant was studied, the basic parameters and their work performance has been designed and optimized.First the performance of the 50KW turbine has been analysised. For the 100KW solar chimney power plant system. The turbine's preliminary design has been done and the overall study, selected the best situation corresponding to the number of leaves, and then gave a comparison between the pros and cons of different situations, and choose the most practical turbine for the solar tower power plant. The design of solar power station turbines has be solved. And analyzed the changes in its performance parameters. The results proved the effectiveness of the design and research methods. In the preliminary design of the turbines based on the turbine blades, some factors such as leaf numbers, leaf types, reverse angle and installation point was carried out and make a series of studies. And a variety of factors analysised. This design laid a certain foundation for the turbine study.Base on the turbines research in the 100kW solar chimney power plant, the 100MW solar power plant has conducted a preliminary turbine design. Identified 32 basic numbers of turbines and circular arrangement around the bottom of the tower, and one of the turbine was designed to study the work, its performance is analyzed and evaluated.The increase of the solar chimney power plant energy conversion efficiency has been solved, it has more advantages to accelerate the promotion and the use of solar energy power plant. Then the basis for the large-scale of the solar energy power plant has provided.
