  • 1. Compact Linear Fresnel Reflector Power Plant 1 MW On Pure Solar Mode 12 hours Operation for Soft Land, Medium InsolationBy and Humid CountrySolar Space Frame Industrial Co., Ltd.Bangkok, ThailandMarch 12, 2555
  • 2. Intro In CSP technology such as Trough, Compact Linear Fresnel Receiver,Solar Tower, Solar Dish Stirling, etc required large area as shading effect. Itneeds high insolation such as 1,000 W/m2 min. It is not suitable to operatein humid and medium insolation such as 500 W/m2. As the structure so longit needs good foundation in Soft-land area. It uses high power for trackingas the system has no sound weight balanced. CSP had high thermal lossesdue to long receiver tubes, long deliver fluid tubes, high temperaturethermal storage, and high working temperature. It required very goodthermal insulation. Once the structure to long it cannot prevented fromtwisting so the structure will be large and heavy. The turbine required high pressure, temperature, and dry steam quality.Also generator required synchronous system when connected to grid. It isnot Easy to transport and assembly. As high technology the operation andmaintenance costs will be high. The material is not easy to find as thesystem use high temperature. We expect the cost of CSP should below 90THB/W, 3.0 US$/W, or 2.1 EURO/W when compare to solar cell. The SolarThermal Dish Steam Turbine with Induction Motor Farm may solve theseproblems and make it possible for commercial.
