GB/T 25841-2017Guide of protection relaying for 1000kV power system (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is GB /Z 25841-2010 "1000kV Power System Relay Protection Technical Guidelines" revision, and GB /Z 25841-2010, in addition to editorial changes, the main technical changes are as follows.

--- Increasing the other voltage level 1000kV substation relay protection of the special requirements;

--- Communication Protocol to delete DL/T 667 requirements, leaving only to meet the requirements of DL/T 860;

--- Cancel the central signal contact output requirements;

--- 1000kV does not consider the smart station, delete the requirements of electronic transformers;

--- For the main line protection, instead of using only the current differential protection, and cancel the corresponding longitudinal distance protection requirements;

--- Line protection added to determine the zero sequence compensation factor requirements;

--- Line protection of non-full phase oscillation and failure occurred outside the assessment;

--- The main transformer, voltage regulator, compensation requirements change prepared separately;

--- Increase the on-load tap-changer protection requirements;

--- Increase 110kV busbar protection and capacitor protection action and start failure requirements;

--- Canceled in accordance with the order of reclosing requirements.

1 Scope

This standard specifies the exchange 1000kV substation and 1000kV substation voltage level has special requirements of the relay protection device The basic guidelines.

This standard applies to 1000kV power system relay protection research, design, manufacture, testing, construction and operation and other fields.
