--- Part 11. Rotary uninterruptible power supply performance requirements and test methods

--- Part 12. Emergency power supply to safety devices this section GB/T 2820 Part 3. This part identical with ISO 8528-3. "Reciprocating internal combustion engine driven alternating current 2005 Generating sets - Part 3. turbine alternator. " this Part replaces GB/T 2820.3-1997 "Reciprocating internal combustion engine driven alternating current generating sets - Part 3. AC generators generator".

This portion of the GB/T 2820.3-1997 compared to a reference standard has made significant changes; related symbols, terms and definitions focus on choreography Chapter 3; the contents of Chapter 14 of the fixed signs have a greater change; modify transient voltage deviation index value when the load increases.

This part is proposed by the China Electrical Equipment Industrial Association.

This part of the mobile station by the National Standardization Technical Committee (SAC/TC329) centralized.

This part mainly drafted by. Lanzhou Institute of power vehicles, Imtech, Ordnance Engineering College, Air Force Radar Academy, Jiangxi Tsinghua Thailand Hao three waves Electric Co., Ltd., Zhengzhou Jinyang Electric Co., Ltd., Guangzhou Technology Limited.

1 Scope

GB/T 2820 This section provides the basic characteristics of AC generators (a.c.) generator voltage regulator under its control, is the relevant requirements of GB 755-2008 supplement.

NOTE. There is no applicable international standard asynchronous generator. When such publication, this part will be amended accordingly.

This section applies to the reciprocating internal combustion (RIC) engine driven land and marine AC (a.c.) generating sets, but not for aviation or driven land vehicles and locomotives turbine generator AC (a.c.).

For some special purposes (such as hospitals, high-rise buildings essential power supply), additional requirements may be needed. The provisions of this section it can be used as the basis to determine any additional requirements.

For other types of reciprocating by a prime mover (such as a steam engine) driven alternating current (a.c.) generator sets, the provisions of this section can be used Basis.

3 Symbols, terms and definitions

When the technical data marked electrical equipment, IEC uses the term "nominal" added the subscript "N" means. In marking machinery and equipment technology Data, ISO uses the term "calibration" plus the subscript "r" indicates. Therefore, in this section, the term "nominal" applies only to the electrical project.

Otherwise, all using the term "calibration." the criteria used symbols and abbreviations explained in Table 1.

Table 1 Symbols, terminology and definitions

Symbol Term Unit Definition Us on the tuning voltage V is defined by the regulator to run the selected line to line voltage Ust, max maximum steady-state voltage V (see GB/T 2820.5-2009) Ust, min minimum steady-state voltage V (see GB/T 2820.5-2009) Ur Rated voltage V Rated frequency and rated output terminals of the generator line of line voltage Note. The rated voltage is based on the operation and performance characteristics given by the manufacturer of voltage.
