ExcDC2A Class

Modified IEEE DC2A direct current commutator exciter with speed input, one more leg block in feedback loop and without underexcitation limiters (UEL) inputs. DC type 2 excitation system model with added speed multiplier, added lead-lag, and voltage-dependent limits.

ka PU Voltage regulator gain (<i>Ka</i>) (&gt; 0). Typical value = 300. 1..1
ks PU Coefficient to allow different usage of the model-speed coefficient (<i>Ks</i>). Typical value = 0. 1..1
ta Seconds Voltage regulator time constant (<i>Ta</i>) (&gt; 0). Typical value = 0,01. 1..1
tb Seconds Voltage regulator time constant (<i>Tb</i>) (&gt;= 0). Typical value = 0. 1..1
tc Seconds Voltage regulator time constant (<i>Tc</i>) (&gt;= 0). Typical value = 0. 1..1
vrmax PU Maximum voltage regulator output (<i>Vrmax</i>) (&gt; ExcDC2A.vrmin). Typical value = 4,95. 1..1
vrmin PU Minimum voltage regulator output (<i>Vrmin</i>) (&lt; 0 and &lt; ExcDC2A.vrmax). Typical value = -4,9. 1..1
ke PU Exciter constant related to self-excited field (<i>Ke</i>). If <i>Ke</i> is entered as zero, the model calculates an effective value of <i>Ke</i> such that the initial condition value of <i>Vr</i> is zero. The zero value of <i>Ke</i> is not changed. If <i>Ke</i> is entered as non-zero, its value is used directly, without change. Typical value = 1. 1..1
te Seconds Exciter time constant, integration rate associated with exciter control (<i>Te</i>) (&gt; 0). Typical value = 1,33. 1..1
kf PU Excitation control system stabilizer gain (<i>Kf</i>) (&gt;= 0). Typical value = 0,1. 1..1
tf Seconds Excitation control system stabilizer time constant (<i>Tf</i>) (&gt; 0). Typical value = 0,675. 1..1
tf1 Seconds Excitation control system stabilizer time constant (<i>Tf1</i>) (&gt;= 0). Typical value = 0. 1..1
efd1 PU Exciter voltage at which exciter saturation is defined (<i>Efd</i><i><sub>1</sub></i>) (&gt; 0). Typical value = 3,05. 1..1
seefd1 Float Exciter saturation function value at the corresponding exciter voltage, <i>Efd</i><i><sub>1</sub></i> (<i>Se[Efd</i><i><sub>1</sub></i><i>]</i>) (&gt;= 0). Typical value = 0,279. 1..1
efd2 PU Exciter voltage at which exciter saturation is defined (<i>Efd</i><i><sub>2</sub></i>) (&gt; 0). Typical value = 2,29. 1..1
seefd2 Float Exciter saturation function value at the corresponding exciter voltage, <i>Efd</i><i><sub>2</sub></i> (<i>Se[Efd</i><i><sub>2</sub></i><i>]</i>) (&gt;= 0). Typical value = 0,117. 1..1
exclim Boolean (<i>exclim</i>). IEEE standard is ambiguous about lower limit on exciter output. true = a lower limit of zero is applied to integrator output false = a lower limit of zero is not applied to integrator output. Typical value = true. 1..1
vtlim Boolean (<i>Vtlim</i>). true = limiter at the block (<i>Ka / [1 + sTa]</i>) is dependent on <i>Vt </i> false = limiter at the block is not dependent on <i>Vt</i>. Typical value = true. 1..1
