Hydropower

IEC 62006:2010 defines the test, the measuring methods and the contractual guarantee conditions for field acceptance tests of the generating machinery in small hydroelectric power installations. It applies to installations containing impulse or reaction turbines with unit power up to about 15 MW and reference diameter of about 3 m. The driven generator can be of synchronous or asynchronous type. This International Standard contains information about most of the tests required for acceptance of the hydraulic turbine such as safety approval tests, trial operating and reliability tests, as well for verification of cavitation, noise and vibration conditions, if required. This standard represents the typical methods used on smaller hydroelectric installations, and is divided into three classes as follows:
Class A: Default, normal test program (panel measurement), to determine the maximum output of the installation.
Class B: Recommended, extended test program, to determine the performance characteristics of the installation.
Class C: Optional, comprehensive test program, to determine the absolute efficiency of the installation.
All classes contain safety tests, trial operating tests, and reliability tests. This standard gives all necessary references for the contract in order to execute the test, evaluate, calculate and compare the result to the guarantee for all the classes A, B and C.

Provides the future purchaser with information allowing him to prepare the required documents, from the call for tenders up to acceptance tests and operation of electromechanical equipment. Applies to installations having outputs of less than 5 MW and turbines with diameters less than 3 m.

This guide applies to any type of reaction or impulse turbine, as well as to any type of pump-turbine and storage pump, coupled to an electric generator or motor. It covers the field of vibration and pulsation tests referred to as standard tests. The contents of the corrigendum of April 1997 have been included in this copy.

Establishes suitable procedures for commissioning, operating and maintaining hydraulic turbines and associated equipment. Applies to impulse and reaction turbines of all types, and especially to large turbines directly coupled to electric generators. Also applies to pump-turbines when operating as turbines, and water conduits, gates, valves, drainage pumps, cooling-water equipment, generators, etc., where they cannot be separated from the turbine and its equipment.

Deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices.

Specifies methods for any size and type of impulse or reaction turbine, storage pump or pump turbine. Determines whether the contract guarantees have been fulfilled and deals with the rules governing these tests as well as the methods of computing the results and the content and style of the final report. Replaces IEC 60198 (1966) and IEC 60607 (1978). The contents of the corrigendum of March 1996 have been included in this copy.
