IEC 60034-22 pdf download Rotating electrical machines – Part 22: AC generators for reciprocating internal combustion (RIC) engine driven generating sets
1 scope
This part of lEC 60034 establishes the principal characteristics of a.c. generators under thecontrol of their voltage regulators when used for reciprocating internal combustion(RIC) enginedriven generating set applications and supplements the requirements given in lEC 60034-1. ltcovers the use of such generators for land and marine use, but excludes generating sets usedon aircraft or used to propel land vehicles and locomotives.
NOTE 1 For some specific applications (e.g. essential hospital supplies, high-rise buildings，etc.) supplementaryrequirements may be necessary.The provisions of this standard should be regarded as a basis for suchrequirements.
NOTE 2 Attention is drawn to the need to take note of additional regulations or requirements imposed by variousregulatory bodies.Such regulations or requirements may form the subject of agreement between the customer andthe 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 tosudden load changes.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
NOTE 1 In this standard, suffix “N” is used for “rated”” in accordance with lEC 60027-1 and IEC 60027-4 whereasin ISO 8528。suffix “r” is so used.
NOTE 2 Voltage terms relate to a generator running at constant (rated) speed under the control of the normalexcitation and voltage control system.
3.1
rated output
S N
the product of the rated r.m.s. voltage, the rated r.m.s. current and a constant m, expressed in volt-amperes (VA) or its decimal multiples
where
m = 1 for single-phase;
m = 2 for two-phase;
m = 3 for three-phase
3.2
rated active power
P N
the product of the rated r.m.s. voltage, the in-phase component of the rated r.m.s. current and a constant m, expressed in watts (W) or its decimal multiples
where
m = 1 for single-phase;
m = 2 for two-phase;
m = 3 for three-phase
3.3
rated power factor
cos φ N
the ratio of the rated active power to the rated output
