(Main)Guidelines to specification of hydraulic turbine governing systems
Guidelines to specification of hydraulic turbine governing systems
IEC 61362:2024 includes relevant technical data necessary to describe hydraulic turbine governing systems and to define their performance. It is aimed at unifying and thus facilitating the selection of relevant parameters in bidding specifications and technical bids. It will also serve as a basis for setting up technical guarantees. The scope of this standard is restricted to the turbine governing level. Additionally some remarks about the control loops of the plant level and about primary and secondary frequency control (see also Annex B) are made for better understanding without making a claim to be complete. Important topics covered are: - speed, power, water level, opening and flow (discharge) control for reaction and impulse-type turbines including double regulated machines; - means of providing actuating energy; - safety devices for emergency shutdown. To facilitate the setting up of specifications, this guide also includes data sheets, which are to be filled out by the customer and the supplier in the various stages of the project and the contract. Acceptance tests, specific test procedures and guarantees are outside the scope of the guide; those topics are covered by IEC 60308. This third edition cancels and replaces the second edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition: adoption of parts of IEC 60308:2005 which deal with specification matters; introduction of several new technical topics; and overall editorial revision. Keywords: Hydraulic turbine, Hydraulic turbine governing systems.
Leitfaden zur Spezifikation der Regeleinrichtung von Wasserturbinen
Lignes directrices pour la spécification des systèmes de régulation des turbines hydrauliques
La IEC 61362:2024 contient les données techniques nécessaires pour décrire les systèmes de régulation des turbines hydrauliques et définir leurs performances. Elle a pour but d'unifier et ainsi de faciliter les spécifications des appels d'offres et les offres techniques. Elle servira également de base pour fixer les garanties techniques. Le domaine d'application de la présente norme est limité au niveau du régulateur turbine. En outre, des remarques sur les boucles de contrôle au niveau de la centrale ainsi que sur le réglage de fréquence primaire et secondaire (voir aussi l'Annexe B) apportent une meilleure compréhension sans avoir la prétention d'être exhaustives. Le guide traite les fonctions importantes suivantes: - les régulations de vitesse, puissance, niveau d'eau, ouverture et débit (décharge) des turbines à réaction et des turbines à action, y compris les machines à double régulation; - les moyens de production de l'énergie de manoeuvre; - les dispositifs de sécurité pour l'arrêt d'urgence, etc. Pour faciliter la rédaction des spécifications, ce guide inclut des formulaires de données à remplir par le client et par le fournisseur aux différentes étapes du projet et du contrat. Les essais de réception, les procédures d´essais spécifiques et les garanties ne sont pas traités par le guide mais par la CEI 60308. Cette troisième édition annule et remplace la seconde édition parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: prise en compte des paragraphes de la deuxième édition de l’IEC 60308 parue en 2005 qui traitent des questions de spécification; présentation de plusieurs nouveaux sujets techniques; et révision rédactionnelle complète. Mots clé: turbines hydrauliques, systèmes de régulation des turbines hydrauliques.
