Foreword
This Standard was formulated for the first time.
This Standard supplements to GB/T 7064 Specific requirements for cylindrical
rotor synchronous machines.
During the formulating, this Standard mainly referred to Draft of Guide on
Synchronous Generator Abnormal Operation submitted by CIGRE11.03
working group in 1980; absorbed the content of turbine generator absorb
reactive power, asynchronous short operation, out-of-step operation,
examination and overvoltage limit after large system disturbance; and added
requirements for special operating conditions such as overcurrent limit,
unbalanced load, frequency’s abnormal operation, out-of-phase
synchronization, single-phase reclosing; as well as start-stop times of generator.
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of Technical Sub-committee on
Generator of National Technical Committee on Rotary Motor of Standardization
Administration of China.
Drafting organizations of this Standard. Harbin Institute of Electronics, North
China Electric Power Research Institute, Hubei Electric Power Research
Institute, Beijing Turbine Generator Co., Ltd., Guangdong Electric Power Test
& Research Institute, and Shanghai Turbine Generator Co., Ltd..
Main drafters of this Standard. Sun Yutian, Bai Yamin, Tong Xusong, Ruan Ling,
Zhuge Wenbing, Yang Chuming, and Liang Xubiao.
This Standard shall be interpreted by Technical Sub-committee on Generator
of National Technical Committee on Rotary Motor of Standardization
Administration of China.
Design application guide of turbo generators under
abnormal operation
1 Scope
This Standard specifies the operating range and degree of turbo generators
under various abnormal operating conditions.
This Standard is applicable to turbo synchronous generators of which the
capacity range is greater than 100 MW.
This Standard can be used as the basis by user and manufacturer when signing
technical agreement. Special requirements for specific products shall be agreed
by both supplier and buyer.
2 Normative references
The following standards contain the provisions which, through reference in this
Standard, constitute the provisions of this Standard. For dated references, the
subsequent amendments (excluding corrections) or revisions do not apply to
this Standard. However, the parties who enter into agreement based on this
Standard are encouraged to investigate whether the latest versions of these
documents are applicable. For undated reference documents, the latest
versions apply to this Standard.
GB 755-2000 Rotating electrical machines - Rating and performance (idt IEC
60034-1. 1996)
GB/T 7064-2002 Requirements for turbine type synchronous machine (IEC
60034-3. 1988, NEQ)
3 Terms and definitions
The following terms and definitions apply to this document.
3.1 asynchronous operation
Asynchronous operation state caused by excitation-loss.
3.2 out-of-step operation
47.0 < F ≤ 46.5 > 2 > 5
4.8 Water-break operation
The allowable water-break operation duration time of water cooled motor is 30
s. If the backup pump cannot restore the water supply within the
aforementioned time, it must be power-trip.
4.9 Out-of-phase synchronization
It shall ensure that the power generator can withstand 180° out-of-phase
synchronization for 5 times or 120° out-of-phase synchronization for 2 times
during its life time.
4.10 Single-phase reclosing-switch
The power generator shall have the capability of withstanding single-phase
high-voltage line reclosing-switch, which shall not affect its reliability.
4.11 Start and stop times of generator set
Two-shift peak-adjustment set is allowed to start and stop for 10000 times
during its life time.
Non two-shift set shall withstand start and stop for 3000 times during its life time.
4.12 Examination on turbo generator after large system disturbance
The turbo synchronous generator shall withstand sudden short circuit of stator
winding outlet end under rated voltage, rated active power and rated power
factor.
Generator shutdown inspection shall be conducted for direct cooling or indirect
cooling turbo generator after withstanding large system disturbance. The
abnormal operation working conditions requiring post inspection are as follows.
- Generator outlet; in some cases, it also includes three-phase or two-
phase sudden short circuit of high-pressure side of step-up transformer of
electrical transformer unit;
- Sudden short circuit of generator transformer unit and system networking
when they are operating near generator transformer proximal end;
- Generators and network operation failure, e.g., out-of-phase
synchronization reclosing-switch;
- Asynchronous operation that exceeds the allowable......
