(Main)Hydraulic turbines - Testing of governing systems (IEC 60308:2024)
Hydraulic turbines - Testing of governing systems (IEC 60308:2024)
IEC 60308:2024 deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices. The significant technical changes introduced by the third edition are the adoption of parts of IEC 61362:2024 which deal with test matters and the introduction of new technical aspects.

Turbines hydrauliques - Essais des systèmes de régulation (IEC 60308:2024)
IEC 60308:2024 traite de la définition et des caractéristiques des systèmes de régulation. Elle n'est pas limitée aux tâches effectives de régulation, mais inclut également d'autres tâches qui peuvent être assignées à un système de régulation, telles que les tâches de commande séquentielle, de sécurité, d'alimentation en énergie de manœuvre. La présente norme couvre les systèmes suivants : régulation de vitesse, puissance, ouverture, niveau d'eau et débit de tous types de turbines; dispositifs électroniques, électriques et d'alimentation en fluide; dispositifs de sécurité; dispositifs de démarrage, et dispositifs d'arrêt. Les changements significatifs introduits dans l’édition 3 sont l’adoption de parties de IEC 61362:2024 concernant les aspects de test et l’introduction plus générale de nouveaux aspects techniques.
