EN 61362:2012

Guide to specification of hydraulic turbine governing systems

IEC 61362:2012 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 second edition cancels and replaces the first edition published in 1998. It is a technical revision. It takes into account the experience with the guide during the last decade as well as the progress in the state of the art of the underlying technologies. Keywords: Hydraulic turbine, Hydraulic turbine governing systems.

Leitfaden zur Spezifikation der Regeleinrichtung von Wasserturbinen

Guide pour la spécification des systèmes de régulation des turbines hydrauliques

La CEI 61362:2012 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 deuxième édition annule et remplace la première édition parue en 1998. Elle constitue une révision technique qui tient compte de l'expérience acquise avec le guide au cours des dix dernières années ainsi que du progrès des technologies sous-jacentes. Mots clé: turbines hydrauliques, systèmes de régulation des turbines hydrauliques.

Vodilo za specificiranje sistemov za krmiljenje hidravličnih turbin

Ta mednarodni standard vključuje zadevne tehnične podatke, potrebne za opis sistemov za krmiljenje hidravličnih turbin in določitev njihove zmogljivosti. Njegov namen je združiti in s tem poenostaviti izbor ustreznih parametrov pri razpisnih specifikacijah in tehničnih ponudbah. Prav tako bo služil kot osnova za ureditev tehničnih jamstev. Področje uporabe tega standarda je omejeno na raven krmiljenja turbin. Poleg tega so za boljše razumevanje navedene nekatere opombe glede krmilnih zank na ravni naprave ter primarne in sekundarne kontrole frekvence (glej tudi dodatek B), vendar niso popolne. Pomembne teme, vključene v navodilih, so: – hitrost, moč, nivo vode, kontrola odpiranja in pretoka (iztoka) za reakcijske in impulzne turbine, vključno z dvojno uravnavanimi stroji; – načini zagotavljanja pogonske energije; – varnostne naprave za izklop v sili itd. Za lažjo določitev specifikacij vključujejo ta navodila tudi obrazce, ki jih stranka in dobavitelj izpolnjujeta v različnih fazah projekta in pogodbe. Testi sprejemljivosti, posebni preskusni postopki in jamstva ne spadajo na področje uporabe navodil; ta vprašanja zajema standard IEC 60308.
