Anotation

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. La IEC 61362:2024 contient les donnees techniques necessaires pour decrire les systemes de regulation des turbines hydrauliques et definir leurs performances. Elle a pour but dunifier et ainsi de faciliter les specifications des appels doffres et les offres techniques. Elle servira egalement de base pour fixer les garanties techniques. Le domaine dapplication de la presente norme est limite au niveau du regulateur turbine. En outre, des remarques sur les boucles de controle au niveau de la centrale ainsi que sur le reglage de frequence primaire et secondaire (voir aussi lAnnexe B) apportent une meilleure comprehension sans avoir la pretention detre exhaustives. Le guide traite les fonctions importantes suivantes: - les regulations de vitesse, puissance, niveau deau, ouverture et debit (decharge) des turbines a reaction et des turbines a action, y compris les machines a double regulation; - les moyens de production de lenergie de manoeuvre; - les dispositifs de securite pour larret durgence, etc. Pour faciliter la redaction des specifications, ce guide inclut des formulaires de donnees a remplir par le client et par le fournisseur aux differentes etapes du projet et du contrat. Les essais de reception, les procedures d´essais specifiques et les garanties ne sont pas traites par le guide mais par la CEI 60308. Cette troisieme edition annule et remplace la seconde edition parue en 2012. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: prise en compte des paragraphes de la deuxieme edition de l’IEC 60308 parue en 2005 qui traitent des questions de specification; presentation de plusieurs nouveaux sujets techniques; et revision redactionnelle complete. Mots cle: turbines hydrauliques, systemes de regulation des turbines hydrauliques.
