keeping generator reactive power
The type of SFPL micro-computer static excitation system

product function
Manifold regulating mode
AVR regulating mode, keeping voltage
MCR regulating mode, keeping generator exciting current
APF regulating mode, keeping generator power factor
AQ regulating mode, keeping generator reactive power
Manifold exciting limit . protect and alarm function
Frequency and voltage limit
No-load over voltage
Low-frequency over excitation protect
Magnetism losing for rotor winding protect
One power supply losing warning
pT fault
Over current for rotor winding protect
pulse losing alarm
Fast fuse protect
Build-up voltage
When the residual voltage > 2% . you can use residual voltage built-up voltage .
Excitation power supply is from DC 220V station used battery and the expending less than 15%-20% no-load excitation current.
Destroy rotor magnetism energy
When generator unload and speed decrease to 85% . the rotor magnetism energy is destroy by adversely converting in stopping generator normally .
When generator is free from network because happening fault , magnesium current breaker is turn off and rotor magnetism energy is destroy quickly by resistor in stopping generator for fault.
