UN 0800A-P VAR.1 HEIR448194 ABB UNITROL excitation

Rectification classification
1. Rotary excitation
Rotary excitation also includes DC AC and brushless excitation.
2. Static excitation
Static exciter includes potential source static exciter and composite power source static exciter.
Ac power supply according to generator excitation mode
1. Ac excitation (separate excitation) system
It is powered by an AC exciter coaxial with the generator. The system can be divided into four ways:
1) AC exciter (magnetic field rotation) plus stationary silicon rectifier (brush).
2) AC exciter (magnetic field rotation) plus static thyristor rectifier (brush).
3) AC exciter (armature rotation) plus silicon rectifier (brushless).
4) AC exciter (armature rotation) plus thyristor rectifier (brushless)..
