IEC 60034-22-2009 Rotating electrical machines - Part 22: AC generators for reciprocating internal combustion (RIC) engine driven generating sets

Language: English, French
International Standard IEC 60034-22 has been prepared by IEC technical committee 2: Rotating machinery.
This second edition cancels and replaces the first edition published in 1996 and constitutes a technical revision.
The technical changes with regard to the previous edition include:
– Clause 2: The standards which were not referenced in the text have been deleted.
– Clause 3: Technical and editorial changes to many of the definitions have been made.
– Clause 4: In the NOTE, the quantity TL has been replaced by TL.
– Clause 7: Technical and editorial changes to many clauses have been made.
– Clause 9: Table 1 has been revised.
– Annex A: This annex has been revised.Scope
This part of IEC 60034 establishes the principal characteristics of a.c. generators under the control of their voltage regulators when used for reciprocating internal combustion (RIC) engine driven generating set applications and supplements the requirements given in IEC 60034-1. It covers the use of such generators for land and marine use, but excludes generating sets used on aircraft or used to propel land vehicles and locomotives.
NOTE 1 For some specific applications (e.g. essential hospital supplies, high-rise buildings, etc.) supplementary requirements may be necessary. The provisions of this standard should be regarded as a basis for such requirements.
NOTE 2 Attention is drawn to the need to take note of additional regulations or requirements imposed by various regulatory bodies. Such regulations or requirements may form the subject of agreement between the customer and the manufacturer when conditions of use of the end product invoke such requirements.
NOTE 3 Examples of regulatory authorities:
− classification societies, for generating sets used on ships and offshore installations;
− government agencies;
− inspection agencies, local utilities, etc.
Annex A discusses the behaviour of generators covered by this standard when subjected to sudden load changes.
