GB/T 2820.1-2022Reciprocating internal combustion engine driven alternating current generating sets - Part 1: Application, ratings and performance (English PDF)

Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020

"Directives for standardization - Part 1: Rules for the structure and drafting of

standardizing documents".

This document is Part 1 of GB/T 2820 "Reciprocating internal combustion engine

driven alternating current generating sets". GB/T 2820 has been published in the

following parts:

- Part 1: Application, ratings and performance;

- Part 2: Engines;

- Part 3: Alternating current generators for generating sets;

- Part 4: Control gear and switchgear;

- Part 5: Generating sets;

- Part 6: Test methods;

- Part 7: Technical declarations for specification and design;

- Part 8: Requirement and tests for low-power generating sets;

- Part 9: Measurement and evaluation of mechanical vibrations;

- Part 10: Measurement of airborne noise by the enveloping surface method;

- Part 11: Rotary uninterruptible power systems - Performance requirements and test

methods.

This document replaces GB/T 2820.1-2009 "Reciprocating internal combustion engine

driven alternating current generating sets - Part 1: Application ratings and performance".

Compared with GB/T 2820.1-2009, in addition to structural adjustments and editorial

changes, the main technical changes are as follows:

- Added the abbreviations "DCP" and "MAX" (see Chapter 4);

- Added the requirements for 10% overload power (see 14.3.3);

- Added the definitions of "Data centre power (DCP)" and "Maximum power for

low-power generating sets (MAX)" (see 14.3.6 and 14.3.7);

Added the requirements for power factor range (see 15.8).

Reciprocating internal combustion engine driven alternating

current generating sets -- Part 1: Application, ratings and

performance

1 Scope

This document defines various classifications for the application, rating and

performance of generating sets consisting of a Reciprocating Internal Combustion (RIC)

engine, Alternating Current (a.c.) generator and any associated control gear, switchgear

and auxiliary equipment.

It applies to a.c. generating sets driven by RIC engines for land and marine use,

excluding generating sets used on aircraft or to propel land vehicles and locomotives.

For some specific applications (e.g. essential hospital supplies, high-rise buildings),

supplementary requirements can be necessary. The provisions of this document can be

the basis for establishing any supplementary requirements.

For other reciprocating-type prime movers (e.g. sewage-gas engines, steam engines),

the provisions of this document can be used as a basis for establishing these

requirements.

Generating sets meeting the requirements of this document are used to generate

electrical power for continuous, peak-load and standby applications. The classifications

laid down in this document are intended to help understanding between manufacturer

and customer.
