Operation and Maintenance Methods in Solar Power Plants
The operation of solar thermal power plants is based on the following steps: (1) mirrors capture solar radiation at a point so as to generate very high temperatures (400–1,000 °C). (2) The obtained heat transforms the water in a steam boiler. (3) Pressurized steam rotates a turbine which drives an alternator.
