13、rs, project contractors, project supervisors, installers, etc.) documents for the setting-up of renewable energy and hybrid systems with a.c. voltage below 500 V, d.c. voltage below 750 V and power below 100 kVA. These documents are recommendations to choose the right system for the right place; to
14、design the system; to operate and maintain the system. These documents are focused only on rural electrification, concentrating on but not specific to, developing countries. They must not be considered as all-inclusive to rural electrification. The documents try to promote the use of renewable energ
15、ies in rural electrification; they do not deal with clean development mechanisms at this time (CO2 emission, carbon credit, etc.). Further developments in this field could be introduced in future steps. This consistent set of documents is best considered as a whole with different parts corresponding
16、 to items for safety, sustainability of systems and at the lowest life-cycle cost as possible. One of the main objectives is to provide the minimum sufficient requirements, relevant to the field of application, that is, small renewable energy and hybrid off-grid systems. The purpose of this part of
17、IEC 62257 is to provide project implementers with general information about generators and to highlight the main characteristics relative to the different technologies that can be used.

18、I RECOMMENDATIONS FOR SMALL RENEWABLE ENERGY AND HYBRID SYSTEMS FOR RURAL ELECTRIFICATION Part 7: Generators 1 Scope The purpose of this part of IEC 62257 is to specify the general requirements for generators (maximum power = 100 kVA) in decentralized rural electrification systems. The aim is to poi
19、nt out the main items that must be considered when selecting, sizing, installing, operating and maintaining this equipment. This technical specification is a general introduction followed by more specific documents dedicated to the generation technologies which are the most currently used in rural e
