Reciprocating internal combustion engine driven alternating current generator set Part 5.Generating sets1 ScopeThis document specifies the terminology, design and performance of machines operating as a combination of a reciprocating internal combustion (RIC) engine and an alternating current (AC) generator. The unit can be operated in conjunction with the mains or not. This document applies to land and marine alternating current (AC) generating sets driven by RIC engines. This document is not applicable to generating sets intended for aviation or for driving land vehicles and locomotives. For some special purposes (such as hospitals, high-rise buildings, essential power supply, etc.), additional requirements may be required. shall serve as the basis for determining any additional requirements. For AC generating sets driven by other types of reciprocating prime movers (e.g. steam engines), the provisions of this document shall apply as Determine the basis for these requirements.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
