GB/T 11920-2008General specification of central control equipment and system for electrical parts in power stations and substations (English PDF)

Foreword

The standard universal basic performance indicators refer to IEC standards and the relevant provisions of the relevant national technical standards, single function indicators root

According to the actual use of domestic requirements developed.

This standard replaces GB 11920-1989 "Electric power plant partially centralized control devices General."

This standard compared with GB 11920-1989, the main differences are as follows.

--- Standard name changed to "power plant electrical parts centralized control equipment and systems - General technical conditions";

--- Increasing the electromagnetic compatibility requirements of content and network control;

--- Other editorial changes.

Appendix A of this standard is an informative annex.

The standard proposed by China Electricity Council.

This standard by the National Standardization Technical Committee on Power System Management and Information Exchange (SAC/TC82) centralized.
