Introduction of GB/T 43595-2023

Directives for commissioning and operation of hydraulic turbines, pump-turbines and storage pumps 1 Scope The purpose of this document is to establish, in a general way, suitable procedures for commissioning and operation of hydraulic machines and associated equipment, and to indicate how such machines and equipment should be commissioned and operated. Commissioning and operation of the associated equipment are not described in detail in this document but is considered in the commissioning and operation procedure as a separate step. Machines of up to about 15 MW and reference diameters of about 3 m are generally covered by IEC 62006. It is understood that a guideline of this type will be binding only if the contracting parties have agreed upon it. The guidelines exclude matters of purely commercial interest, except those inextricably connected with the conduct of commissioning and operation. The guidelines are not concerned with waterways, gates, drainage pumps, cooling-water equipment, generators, motor-generators, electrical equipment (e.g. circuit breakers, transformers) etc., except where they cannot be separated from the hydraulic machinery and its equipment. Wherever the guidelines specify that documents, drawings or information are supplied by a supplier (or by suppliers), each individual supplier should furnish the appropriate information for its own supply only. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 Machine and equipment 3.1.1 hydraulic machinery turbines, storage pumps, pump-turbines, valves, guide and thrust bearings used in hydroelectric power and pumped storage stations Note 1: The term hydraulic machinery includes hydraulic torque converter and all type of main inlet valves. Note 2: Terms related to hydro turbine governing systems are not included; refer to IEC 60308.

Note 2: The term turbine does not include the inlet or outlet valves nor the associated generator or governor. [SOURCE: IEC TR 61364:1999, 4.1, modified] 3.1.4 pump machine for transforming mechanical energy into hydraulic energy in order to store water that will be used later on to produce electric energy Note 1: The term pump includes a storage pump and a pump-turbine functioning as a pump. Note 2: The term pump does not include the inlet or outlet valves nor the associated motor.
