Series:ABB UAC series(high-voltage transmission line protection device)

Core positioning:

Designed for transmission lines with voltage levels of 220kV and above,it provides core functions such as longitudinal differential protection,distance protection,and directional overcurrent protection.

Applicable to key scenarios such as long-distance transmission lines,tie lines,and large-capacity generator-transformer group exports.

2.Hardware specifications

1.Protection function

Longitudinal differential protection(main protection):

Compare the currents at both ends of the line through optical fiber or carrier channel,and quickly remove faults in the area(action time≤20ms).

Supports phase differential and zero-sequence differential to adapt to different fault types.

Distance protection(backup protection):

Three-stage distance protection:

Distance section I:instantaneous action,protecting 80%-85%of the total length of the line.

Distance section II:with delayed action,protecting the end of the line and the adjacent line section.

Distance section III:long delay action,as remote backup protection.

Directional judgment:distinguish between internal/external faults through power direction elements.

Directional overcurrent protection:

Combined with current amplitude and direction elements,as a backup for distance protection.

Zero sequence protection:

Detect single-phase grounding faults,support zero sequence current protection and zero sequence directional protection.

Other protections:

Overvoltage protection:monitor abnormal increase in line voltage(such as operating overvoltage).

Low frequency load shedding:automatically cut off non-critical loads when system frequency drops.
