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.
