Achievement report on the development of solar thermal electric power plant technologies. Annex; Taiyonetsu hatsuden plant gijutsu kaihatsu seika hokokusho. Fuzoku shiryo

Abstract

The two solar thermal electric power pilot plants are of the tower concentration type and the flat/curved surface concentration type. For the first time in the world, they succeeded in operating at a rated output of 1,000kW in August and September, 1981, respectively. Sunshine was inputted at an unstable rate, and the plants were operated under various load patterns. Studies were conducted and an optimum operating technique is established. Since designing, construction, and operation were carried for two types of pilot plants, quantities of useful data were collected through a variety of experiences. Valuable hints and design data were provided for use in the construction of full-scale power plants in the future. Element units developed for the plants were high-reflectance mirrors, high-precision tracking mechanisms, solar heat collectors of the cavity type and paraboloidal type, and molten salt heat accumulators. The tower concentration type plant exhibits a power generation efficiency of 16-17% and an overall plant efficiency of 3.1-4.4%. The maximum overall efficiency a month is 3.9% with the flat/curved surface concentration type plant. (NEDO)
