Solar thermal electric plants - Part 1-5: Performance code test for solar thermal electric plants

IEC 62862-1-5:2024 provide procedures and guidelines to carry out acceptance tests for solar thermal power plants, of any concentration technology, with the uncertainty level given in ISO/IEC Guide 98-3.
This document 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.
This document specifies the characteristics of a calculation tool that serves as a reference for expected electricity production during the test period and under real-time solar irradiance and other meteorological data.
This document is applicable to solar thermal power plants of any size using any concentration technology, where the sun is the main source of energy, and all elements and systems are operative. Such power plants can optionally have non-solar energy sources, such as natural gas or other renewable energies, and a thermal storage system.
This document is applicable to acceptance testing in such power plants, as well as in any other scenario in which their performance must be known.

Centrales électriques solaires thermiques - Partie 1-5 : Essai du code de performance pour les centrales électriques thermosolaires

IEC 62862-1-5:2024 fournir des procédures et des lignes directrices pour effectuer des essais de réception des centrales électriques solaires thermodynamiques, de toute technologie de concentration, avec le niveau d’incertitude indiqué dans le Guide ISO/IEC 98-3.
Le présent document établit les mesurages, l’instrumentation et les techniques exigés pour déterminer les paramètres de performance suivants pour une période donnée:
- énergie de rayonnement solaire disponible,
- consommations électriques de la centrale,
- production nette d’électricité,
- énergie non solaire,
- rendement net de la centrale
Le présent document spécifie les caractéristiques d’un outil de calcul qui sert de référence pour la production d’électricité prévue dans la période d’essai et sous l’éclairement solaire en temps réel, et compte tenu d’autres données météorologiques.
Le présent document s’applique aux centrales électriques solaires thermodynamiques de toute taille qui utilisent toute technologie de concentration, avec lesquelles le soleil est la principale source d’énergie et tous les éléments et systèmes fonctionnent.
Le présent document s’applique aux essais de réception dans de telles centrales, ainsi que dans tout autre scénario dans lequel leurs performances doivent être connues.
