二次反射塔式电站运行测试与模拟研究
Run-test and simulation research of a beam-down concentrating solar power plant
摘要
Abstract
The beam-down concentrating solar power plant has the advantages of high concentrating ratio,low installation and maintenance requirements,and low pump consumption.Relying on the 50 MW beam-down tower concentrating solar power station in Yumen Xinneng First Power Co.,Ltd.,the mathematical models of the heliostat field,hyperboloid mirror,receiver,molten salt tank,and power generation cycle are established and verified.The run-test results reveal that,the maximum outlet temperature of the molten salt can be maintained at 559℃for 50 minutes at an average direct normal irradiation of 739.70 W/m2.The cosine efficiency,shading and blocking efficiency,shading efficiency of the hyperboloid mirror,and attenuation efficiency of the heliostat field at 12:00 are 0.856 8,0.999 7,0.994 1,and 0.974 6,respectively.The average hyperboloid mirror flux density and receiver flux density are 11.3 kW/m2 and 400.5 kW/m2,respectively.Meanwhile,the power station is maintained for 16 h at the rated generation power of 50 MW.The research has certain reference significance for the operation of a beam-down concentrating solar power plant.关键词
