Evaluation of the Proposed Solar Electric Dispersed System Power Plant in Newton County, Arkansas

摘要

The proposed program is directed toward the development of a 5 MWe demonstration solar power plant to be located in Northern Arkansas. The plant is to consist of 1300 individual solar two-axis tracker concentrators, each with its own heat engine and electric generator of slightly more than 3 kWe capacity. Advanced plastic and materials fabrication techniques are to be used for concentrator/generator unit construction in an effort to reduce unit weight and cost/M exp 2 . A system of iron chloride redox batteries is proposed for electrical storage. When operational, the power produced by the solar plant will be integrated into the local power distribution network. The proposed program consists of three phases. The first one and one-half year phase covers the development of the basic component parts of the system: support, concentrator, heat receiver, engine, generator, and control. The second one-year phase integrates the component parts and conducts development and testing on the completed module. The third phase of one and one-half years concerns the installation and checkout of the entire 5 MWe system. (ERA citation 04:022154)
