Guidance for installation procedures and tolerances of hydroelectric machines - Part 5: Bulb turbines and generators

Guidance for installation procedures and tolerances of hydroelectric machines - Part 5: Bulb turbines and generators

The purpose of this guide is to establish, in a general way, suitable procedures and tolerances for the installation of bulb turbine and generator. This guide presents a typical assembly and whenever the words "turbine" and "generator" are used in this part, it refers to bulb turbine and generator. There are many possible ways to assemble a unit. The size of the machine, the design of the machine, the layout of the powerhouse, the sequence of concreting or the delivery schedule of the components are some of the elements that could result in additional steps, or the elimination of some steps and/or assembly sequences. It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it. The guide excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation. It also excluded to specifications of the civil works but this aspect of the work should be taken into consideration during the assembly of the units. Wherever the guide specifies that documents, drawings or information is supplied by a manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate information for their own supply only.

Lignes directrices des procédures et tolérances d’installation des machines hydroélectriques - 5: Turbines et alternateurs de type bulbe

IEC 63132-5:2023 doit établir, de manière générale, des procédures et des tolérances appropriées pour l’installation de turbines et de générateurs hydroélectriques. Ce guide présente un assemblage typique. Il faut reconnaître qu’il existe de nombreuses façons possibles d’assembler une unité. La taille des machines, la conception des machines, la disposition de la centrale et le calendrier de livraison des composants sont quelques-uns des éléments qui pourraient entraîner des étapes supplémentaires, l’élimination de certaines étapes et / ou des séquences d’assemblage.

Navodila za postopke vgradnje in tolerance hidroelektričnih strojev - 5. del: Cevne (Kaplanove) turbine in generatorji (IEC 63132-5:2023)

Namen teh navodil je na splošno vzpostaviti ustrezne postopke in dovoljene tolerance za vgradnjo cevnih (Kaplanovih) turbin in generatorjev. V navodilih je predstavljen tipični sestav, izraza »turbina« in »generator« pa se povsod navezujeta na cevno (Kaplanovo) turbino in generator. Enoto je mogoče sestaviti na več načinov. Velikost in zasnova stroja, postavitev elektrarne, zaporedje betoniranja ter razpored dobave komponent so nekateri od elementov, ki lahko zahtevajo dodatne korake ali odpravo nekaterih postopkov in/ali korakov sestavljanja.
Publikacija te vrste je zavezujoča le, če in v obsegu, v katerem jo potrdita obe pogodbenici.
Navodila ne zajemajo izključno komercialnih interesov, razen tiste, ki so neločljivo povezani z izvajanjem vgradnje. Prav tako niso zajete specifikacije gradbenih del, vendar je priporočljivo ta vidik del upoštevati pri sestavljanju enot.
Če je v navodilih navedeno, da dokumente, skice ali informacije zagotovi proizvajalec (ali proizvajalci), bo vsak posamezni proizvajalec predložil samo ustrezne informacije za lastno dobavo.

Guidelines to specification of hydraulic turbine governing systems
SIST EN IEC 61362:2024

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.

Pelton hydraulic turbines - Model acceptance tests
SIST EN IEC 63461:2024

IEC 63461:2024 applies to laboratory model tests of any type of Pelton hydraulic turbine with unit power greater than 5 MW. It contains the rules governing test conduct and provides 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; - and to define the extent, content and structure of the final report. Full application of the procedures herein described is not generally justified for machines with smaller power. Nevertheless, this document can be used for such machines by agreement between the purchaser and the supplier.

Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests
SIST EN IEC 60193:2019

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.

Hydraulic machines - Guidelines for dealing with hydro-abrasive erosion in kaplan, francis and pelton turbines
SIST EN IEC 62364:2019

IEC 62364:2019 is available as IEC 62364:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62364:2019 gives guidelines for: a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites; b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site; c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems; d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings; e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers; f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life. It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues. It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation. Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydro-abrasive erosion resistant coatings can also be damaged locally by impact of large solids. It is beyond the scope of this document to address these issues. This document focuses mainly on hydroelectric powerplant equipment. Certain portions can also be applicable to other hydraulic machines. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the formula for TBO in Pelton reference model has been modified; b) the formula for calculating sampling interval has been modified; c) the chapter in hydro-abrasive erosion resistant coatings has been substantially modified; d) the annex with test data for hydro-abrasive erosion resistant materials has been removed; e) a simplified hydro-abrasive erosion evaluation has been added. Key words: Hydraulic Machines, Hydro-Abrasive Erosion, Kaplan, Francis, Pelton T
