GB/T 9652.2-2019Testing specification of hydraulic turbine governing systems (English PDF)

Foreword

GB/T 9652 is divided into the following two parts.

---GB/T 9652.1 Technical requirements for turbine governing system;

---GB/T 9652.2 Hydraulic turbine governing system test.

This part is the second part of GB/T 9652.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 9652.2-2007 "Engine Control System Test", compared with GB/T 9652.2-2007 main technical changes

The following is as follows.

--- The scope of application has been modified and supplemented (see Chapter 1, Chapter 1 of the.2007 edition);

--- The test conditions have been modified and supplemented (see 3.2, 3.4.1,.2007 edition 3.3.1, 3.3.4);

--- Added or modified the hydraulic pressure device adjustment test content (see 6.1.2, 6.2.1, 6.2.2, 6.3.1, 6.3.2, 6.3.3,.2007)

Versions 6.27.1, 6.27.2, 6.28.2, 6.28.3);

--- Considering that the mechanical hydraulic governor and analog circuit governor have been discontinued in China for more than ten years, the current turbine governor products are

It is a microcomputer type governor, so the relevant provisions of the mechanical hydraulic governor and the analog circuit electro-hydraulic governor have been deleted (see the.2007 edition).

6.1.4, 6.3, 6.10.1, 6.10.2, 6.10.3);

--- Supplemented the test content of the frequency measurement link (see 6.10.2);

--- Supplemented the test content of the electrical-mechanical/hydraulic conversion components (see 6.11.3, 6.11.5);

--- Supplementary method for determining the reaction time of the relay (see 6.14, 6.19 of the.2007 edition);

--- Supplement and adjust the adjustment parameter calibration method of the microcomputer regulator (see 6.16, 6.11 of the.2007 edition);

--- Added the test content of the pump turbine governing system (see 6.20, 6.33, 6.34, 6.35, 6.36, 6.38);

--- Added the hydraulic drift test content (see 6.24);

--- Supplementary to the no-load disturbance test method (see 6.26.2, 6.21 of the.2007 edition);

--- Increased load adjustment test content (see 6.27);

--- Removed the oil pump shaft power test, efficiency test, vibration test, etc. (see the.2007 edition of 6.27.2.2, 6.27.2.3,

6.27.2.4, 6.27.2.5, 6.27.2.6, 6.27.2.7, 6.27.3, 6.27.4, 6.27.5);

--- Added a frequency modulation test, modeling test content (see 6.28, 6.29);

---Adjust and supplement the experimental content of the isolated network adjustment (see 6.30, 6.22 of the.2007 edition);

--- Adjusted and improved Appendix A (see Appendix A, Appendix A of the.2007 edition).

This part uses the redrafting method to refer to IEC 60308.2005 "Engine Control System Test", and IEC 60308.2005

The degree of consistency is non-equivalent.

This part was proposed by China Electrical Equipment Industry Association.

This part is under the jurisdiction of the National Turbine Standardization Technical Committee (SAC/TC175).
