Question

Q4 A Solar power plant in Ibri region is proposed to generate a power of 250 MW to cater the power to the nearby villages. The hot steam generated from the solar collector is used to run the turbine to produce the mechanical energy, which has an efficiency of 36%. The turbine is coupled with a turbo generator, having an efficiency of 18.65%. How much collector area will be needed if the collector has an efficiency of 22.5%? Compare and analyze your results for the maximum and minimum solar radiation for the above-mentioned area. Portray the above solar system and accessories with a suitable diagram. Do you think 250 MW power production is practically feasible? If yes, what type of solar collector is widely used for power production? justify your answers with suitable references and facts.
