IEEE (1992/2005) DC1A Model This model is used to represent field-controlled dc commutator exciters with continuously acting voltage regulators (especially the direct-acting rheostatic, rotating amplifier, and magnetic amplifier types). Because this model has been widely implemented by the industry, it is sometimes used to represent other types of systems when detailed data for them are not available or when a simplified model is required.

ka - Gain (> 0.)
e1 - Field voltage value 1 (> 0.)
tb - Lag time constant (>= 0.)
se2 - Saturation factor at e2 (>= 0.)

exclim - If not 0, apply lower limit of 0. to exciter output
e2 - Field voltage value 2. (> 0.)
tr - Filter time constant (>= 0.)
uelin - UEL input: if < 2, HV gate; if = 2, add to error signal
tf - Rate feedback time constant, sec. (> 0.)
vrmax - Maximum controller output
kf - Rate feedback gain (>= 0.)
ke - Exciter field resistance line slope
se1 - Saturation factor at e1 (>= 0.)
vrmin - Minimum controller output (< 0.)
tc - Lead time constant
