This part applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine.
This part applies to models of prototype machines either with unit power greater than 10MW or with reference diameter greater than 3.3m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size. Nevertheless, this part may be used for such machines by agreement between purchaser and supplier.
In this part, the term "turbine" includes a pump-turbine operating as a turbine and the term "pump" includes a pump-turbine operating as a pump.
This part excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests.
This part is concerned with neither the structural details of the machines nor the mechanical performance of their components, so long as these do not affect model performance or the relationship between model and prototype performances.
1.2 Object
This part 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 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 part 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, which fall within the scope of this part, have been fulfilled;
——to define the extent, content and structure of the final report.
The guarantees may 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 GB/T 15613.2 related to main hydraulic performance, the information of these additional data given in GB/T 15613.3 is considered only as recommendation or guidance to the user.
It is particularly recommended that model acceptance tests be performed if the expected field conditions for acceptance tests (see GB/T 20043) would not allow the verification of guarantees given for the prototype machine.
This part may also be applied to model tests for other purposes, i.e. comparative tests and research and development work.
If model acceptance tests have been performed, field tests can be limited to index tests (see Chapter 8, GB/T 20043).
