Stability Tuning DECS-250
Overexcitation Limiter (OEL)
The integral gain (K
i
) adjusts the rate at which the DECS-250 responds during an overexcitation
condition.
The integral loop gain (K
g
) adjusts the coarse loop-gain level of the PI algorithm for the overexcitation
limiter function.
Underexcitation Limiter (UEL)
The integral gain (K
i
) adjusts the rate at which the DECS-250 responds during an underexcitation
condition.
The loop gain (K
g
) adjusts the coarse loop-gain level of the PI algorithm for the underexcitation limiter
function.
Stator Current Limiter (SCL)
The integral gain (K
i
) adjusts the rate at which the DECS-250 limits stator current.
The loop gain (K
g
) adjusts the coarse loop-gain level of the PI algorithm for the stator current limiter
function.
Var Limiter
The integral gain (K
i
) adjusts the rate at which the DECS-250 limits reactive power.
The loop gain (K
g
) adjusts the coarse loop-gain level of the PID algorithm for the reactive power limiter
function.
Voltage Matching
The integral gain (K
i
) adjusts the rate at which the DECS-250 matches the generator voltage to the bus
voltage.
