DANSK DSF/PREN IEC 62862-1-5 PDF

The purpose of this standard is to provide procedures and guidelines to carry out acceptance tests for solar thermal power plants, of any concentration technology, with the uncertainty level given in the ISO/IEC Guide 98-3. This standard establishes the measurements, instrumentation and techniques required for determining the following performance parameters for a given period: • Available solar radiation energy • Plant electricity consumptions • Net electricity generation • Non-solar energy • Net plant efficiency Other parameters that characterize the solar thermal power plant system features are not dealt with in this standard but are the subject of other complementary standards. Due to the variability of the sun as the energy source for a solar power plant, it is necessary to compare any measured production data (performance) of the system to a jointly agreed calculation tool serving as a reference for expected production in the specific period and under the real-time solar irradiance and other meteorological data.
