(Main)Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests
Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests
This document applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This document applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size. Nevertheless, this document may be used for such machines by agreement between the purchaser and the supplier. In this document, the term "turbine" includes a pump-turbine operating as a turbine and the term "pump" includes a pump-turbine operating as a pump. This document excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests. This document is concerned with neither the structural details of the machines nor the mechanical properties of their components, so long as these do not affect model performance or the relationship between model and prototype performances. This document covers the arrangements for model acceptance tests to be performed on hydraulic turbines, storage pumps and pump-turbines to determine if the main hydraulic performance contract guarantees (see 4.2) have been satisfied. It contains the rules governing test conduct and prescribes measures to be taken if any phase of the tests is disputed. The main objectives of this document are: - to define the terms and quantities used; - to specify methods of testing and of measuring the quantities involved, in order to ascertain the hydraulic performance of the model; - to specify the methods of computation of results and of comparison with guarantees; - to determine if the contract guarantees that fall within the scope of this document have been fulfilled; - to define the extent, content and structure of the final report. The guarantees can be given in one of the following ways: - guarantees for prototype hydraulic performance, computed from model test results considering scale effects; - guarantees for model hydraulic performance. Moreover, additional performance data (see 4.4) can be needed for the design or the operation of the prototype of the hydraulic machine. Contrary to the requirements of Clauses 4 to 6 related to main hydraulic performance, the information of these additional data given in Clause 7 is considered only as recommendation or guidance to the user (see 7.1). It is particularly recommended that model acceptance tests be performed if the expected field conditions for acceptance tests (see IEC 60041:1991) would not allow the verification of guarantees given for the prototype machine. A transposition method taking into account the model and prototype wall surface roughness for the performance conversion on pump-turbines, Francis turbines, and axial machines is described in IEC 62097. This method requires model and prototype surface roughness data and is takes into account the shift in nED, QED and PED factors for determining the transposition of efficiency between model and prototype. However, in the case of Francis machines with semispiral casing and axial machines, the transposition method has not been fully validated due to a lack of data. In addition, IEC 62097 does not apply to storage pumps, Pelton turbines, and Dériaz. Therefore, for these and otherwise specifically agreed upon cases where hydraulically smooth flow conditions are assumed on the model and the prototype, the transposition formula and procedure given in Annex D and Annex I can be applied. Applications and limitations of both this document and IEC 62097 transposition methods are discussed in Annex E. The method for performance conversion from model to prototype needs to be clearly defined in the main hydraulic performance contract.
Hydraulische Turbinen, Speicherpumpen und Pumpturbinen - Modellabnahmeprüfungen
Turbines hydrauliques, pompes d'accumulation et pompes-turbines - Essais de réception sur modèle
Le présent document est applicable aux modèles de laboratoire de tout type de turbine hydraulique à action ou à réaction, de pompe d'accumulation ou de pompe-turbine. Il s'applique aux modèles de machines prototypes ayant une puissance unitaire supérieure à 5 MW ou un diamètre de référence supérieur à 3 m. Bien que l'application intégrale des procédures prescrites ne soit généralement pas justifiée pour des machines de puissance et de dimension inférieures, le présent document peut néanmoins être utilisé pour de telles machines après accord entre l'acheteur et le fournisseur. Dans ce document, le terme "turbine" inclut une pompe-turbine fonctionnant en turbine et le terme "pompe" inclut une pompe-turbine fonctionnant en pompe. Ce document exclut tous les sujets à caractère purement commercial, excepté ceux intimement liés à la bonne conduite des essais. Ce document ne concerne ni les détails de construction des machines, ni les propriétés mécaniques de leurs différentes parties pour autant que ces éléments n'affectent pas le fonctionnement du modèle ni la relation entre les performances du modèle et celles du prototype. Le présent document régit les modalités des essais de réception sur modèle des turbines hydrauliques, pompes d'accumulation et pompes-turbines en vue de déterminer si les garanties contractuelles de performances hydrauliques principales (voir 4.2) sont respectées. Il fixe les règles qui gouvernent la conduite de ces essais et prescrit les mesures à prendre en cas de contestation d'une phase quelconque des essais. Les objectifs principaux du présent document sont: - de définir les termes et les grandeurs utilisés; - de prescrire les méthodes d'essai et les façons de mesurer les grandeurs permettant d'évaluer les performances hydrauliques du modèle; - de prescrire les méthodes de calcul des résultats et de comparaison aux garanties; - de déterminer si les garanties contractuelles qui sont du domaine de ce document sont respectées; - de définir l'étendue, le contenu et la présentation du rapport final. Les garanties peuvent être données de l'une des façons suivantes: - garanties reposant sur les performances hydrauliques du prototype, calculées à partir des résultats d'essai du modèle en tenant compte des effets d'échelle; - garanties reposant sur les performances hydrauliques du modèle. Par ailleurs des données complémentaires de fonctionnement (voir 4.4) peuvent être nécessaires pour la conception ou l'exploitation de la machine hydraulique prototype. Contrairement aux exigences indiquées aux Articles 4 à 6 relatives aux performances hydrauliques principales, les informations sur ces données complémentaires décrites à l'Article 7 ne sont considérées que comme des recommandations ou des conseils à l'utilisateur (voir 7.1). Il est particulièrement recommandé d'effectuer les essais de réception sur modèle lorsque les conditions pratiques dans lesquelles seraient faits des essais de réception sur le site (voir l'IEC 60041) ne permettraient pas de prouver le respect des garanties données pour le prototype. Une méthode de transposition tenant compte de la rugosité des surfaces entre le modèle et le prototype pour les pompes-turbines, les turbines Francis et les turbines axiales est décrite dans l'IEC 62097. Cette méthode requiert les valeurs de rugosité des surfaces modèle et prototype, respectivement et tient compte du décalage en nED, QED et PED afin de calculer la transposition entre le modèle et le prototype. Par contre, cette nouvelle méthode de calcul de transposition n'a pas été complètement validée en raison d'un manque de données pour les turbines Francis avec bâche fronto-spirale et les turbines axiales. De plus, l'IEC 62097 ne s'applique pas aux pompes d'accumulation, aux turbines Pelton et Dériaz.
Vodne turbine, akumulacijske črpalke in črpalne turbine - Prevzemni preskusi modela (IEC 60193:2019)
Ta dokument se uporablja za laboratorijske modele vseh vrst impulznih ali reaktivnih vodnih turbin, akumulacijskih črpalk in črpalnih turbin.
Ta dokument se uporablja za modele prototipnih strojev z močjo enote, večjo od 5 MW, ali referenčnim premerom, večjim od 3 m. Celotna uporaba postopkov, ki je opisana v tem dokumentu, na splošno ni utemeljena za stroje manjše moči in velikosti. Kljub temu se lahko ta dokument uporablja za take stroje po dogovoru med kupcem in dobaviteljem.
V tem dokumentu izraz »turbina« vključuje črpalno turbino, ki deluje kot turbina, izraz »črpalka« pa vključuje črpalno turbino, ki deluje kot črpalka.
Ta dokument izključuje vse izključno komercialne interese, razen tistih, ki so neločljivo povezani z izvajanjem teh preskusov.
Ta dokument ne opredeljuje strukturnih podrobnosti strojev niti mehanskih lastnosti njihovih komponent, če te ne vplivajo na zmogljivost modela ali na razmerje med zmogljivostjo modela in prototipa.
Ta dokument zajema dogovore za prevzemne preskuse modela, ki bodo opravljeni na vodnih turbinah, akumulacijskih črpalkah in črpalnih turbinah, da se ugotovi, ali so izpolnjena pogodbena jamstva glede hidravlične zmogljivosti (glej točko 4.2).
Vsebuje pravila, ki urejajo izvajanje preskusov in predpisujejo ukrepe, ki jih je treba izvesti v primeru sporov glede ene od faz preskusov.
Glavni namen tega dokumenta je:
– definirati uporabljane izraze in količine;
– določiti metode za preskušanje in merjenje vključenih količin, da se opredeli hidravlična zmogljivost modela;
– določiti metode za izračun rezultatov in primerjavo z jamstvi;
– določiti, ali so pogodbena jamstva, ki spadajo na področje uporabe tega dokumenta, izpolnjena;
– določiti obseg, vsebino in strukturo končnega poročila.
Ta jamstva je mogoče podati na enega od naslednjih načinov:
– jamstva za hidravlično zmogljivost prototipa, izračunano na podlagi rezultatov preskusa modela ob upoštevanju učinkov obsega;
– jamstva za hidravlično zmogljivost modela.
Poleg tega so lahko za zasnovo ali obratovanje prototipa vodnega stroja potrebni dodatni podatki o zmogljivosti (glej točko 4.4). V nasprotju z zahtevami iz točk od 4 do 6 v zvezi z glavno hidravlično zmogljivostjo se informacije teh dodatnih podatkov iz točke 7 obravnavajo zgolj kot priporočilo ali vodilo za uporabnika (glej točko 7.1).
Zlasti se priporoča, da se prevzemni preskusi modela opravijo, če pričakovani terenski pogoji za prevzemne preskuse (glej standard IEC 60041:1991) ne omogočajo preverjanja jamstev, ki so navedena za prototipni stroj.
Metoda prenosa, ki za pretvorbo zmogljivosti črpalnih turbin, Francisovih turbin in aksialnih strojev upošteva površinsko hrapavost modela in prototipa, je opisana v standardu IEC 62097. Za to metodo so potrebni podatki o površinski hrapavosti modela in prototipa, pri čemer se upoštevajo spremembe faktorjev nED, QED ter PED za določanje prenosa učinkovitosti med modelom in prototipom. Vendar pa pri Francisovih strojih s polspiralastim ohišjem in aksialnih strojih metoda prenosa ni v celoti preverjena zaradi pomanjkanja podatkov. Poleg tega se standard IEC 62097 ne uporablja za akumulacijske črpalke, Peltonove turbine in Dériaz. Tako je mogoče za te in druge posebej dogovorjene primere, pri katerih so pogoji hidravlično nemotenega pretoka predpostavljeni glede na model in prototip, uporabiti formulo ter postopek prenosa, ki sta navedena v dodatku D in dodatku I. Načini uporabe in omejitve metod prenosa iz tega dokumenta in standarda IEC 62097 so obravnavane v dodatku E. Metodo za pretvorbo zmogljivosti modela v zmogljivost prototipa je treba jasno opredeliti v glavni pogodbi o hidravlični zmogljivosti.
