The electrical equations of all variations of the asynchronous model are based on the AsynchronousEquivalentCircuit diagram for the direct and quadrature axes, with two equivalent rotor windings in each axis.
Equations for conversion between Equivalent Circuit and Time Constant Reactance forms:
Xs = Xm + Xl
X' = Xl + Xm * Xlr1 / (Xm + Xlr1)
X'' = Xl + Xm * Xlr1* Xlr2 / (Xm * Xlr1 + Xm * Xlr2 + Xlr1 * Xlr2)
T'o = (Xm + Xlr1) / (omega0 * Rr1)
T''o = (Xm * Xlr1 + Xm * Xlr2 + Xlr1 * Xlr2) / (omega0 * Rr2 * (Xm + Xlr1)
Same equations using CIM attributes from AsynchronousMachineTimeConstantReactance class on left of = sign and AsynchronousMachineEquivalentCircuit class on right (except as noted):
xs = xm + RotatingMachineDynamics.statorLeakageReactance
xp = RotatingMachineDynamics.statorLeakageReactance + xm * xlr1 / (xm + xlr1)
xpp = RotatingMachineDynamics.statorLeakageReactance + xm * xlr1* xlr2 / (xm * xlr1 + xm * xlr2 + xlr1 * xlr2)
tpo = (xm + xlr1) / (2*pi*nominal frequency * rr1)
tppo = (xm * xlr1 + xm * xlr2 + xlr1 * xlr2) / (2*pi*nominal frequency * rr2 * (xm + xlr1).

The class represents IEEE Std 421.5-2005 type AC3A model. The model represents the field-controlled alternator-rectifier excitation systems designated Type AC3A. These excitation systems include an alternator main exciter with non-controlled rectifiers. The exciter employs self-excitation, and the voltage regulator power is derived from the exciter output voltage. Therefore, this system has an additional nonlinearity, simulated by the use of a multiplier
whose inputs are the voltage regulator command signal, Va, and the exciter output voltage, Efd, times KR. This model is applicable to excitation systems employing static voltage regulators.

The class represents IEEE Std 421.5-2005 type AC4A model. The model represents type AC4A alternator-supplied controlled-rectifier excitation system which is quite different from the other type ac systems. This high initial response excitation system utilizes a full thyristor bridge in the exciter output circuit. The voltage regulator controls the firing of the thyristor bridges. The exciter alternator uses an independent voltage regulator to control its output voltage to a constant value. These effects are not modeled; however, transient loading effects on the exciter alternator are included.

The class represents IEEE Std 421.5-2005 type AC5A model. The model represents a simplified model for brushless excitation systems. The regulator is supplied from a source, such as a permanent magnet generator, which is not affected by system disturbances. Unlike other ac models, this model uses loaded rather than open circuit exciter saturation data in the same way as it is used for the dc models. Because the model has been widely implemented by the industry, it is sometimes used to represent other types of systems when either detailed data for them are not available or simplified models are required.

The class represents IEEE Std 421.5-2005 type AC8B model. This model represents a PID voltage regulator with either a brushless exciter or dc exciter. The AVR in this model consists of PID control, with separate constants for the proportional (KPR), integral (KIR), and derivative (KDR) gains. The representation of the brushless exciter (TE, KE, SE, KC, KD) is similar to the model Type AC2A. The Type AC8B model can be used to represent static voltage regulators applied to brushless excitation systems. Digitally based voltage regulators feeding dc rotating main exciters can be represented with the AC Type AC8B model with the parameters KC and KD set to 0. For thyristor power stages fed from the generator terminals, the limits VRMAX and VRMIN should be a function of terminal voltage: VT * VRMAX and VT * VRMIN.

The class represents IEEE Std 421.5-2005 type DC3A model. This model represents represent older systems, in particular those dc commutator exciters with non-continuously acting regulators that were commonly used before the development of the continuously acting varieties. These systems respond at basically two different rates, depending upon the magnitude of voltage error. For small errors, adjustment is made periodically with a signal to a motor-operated rheostat. Larger errors cause resistors to be quickly shorted or inserted and a strong forcing signal applied to the exciter. Continuous motion of the motor-operated rheostat occurs for these larger error signals, even though it is bypassed by contactor action.

The class represents IEEE Std 421.5-2005 type ST3A model. Some static systems utilize a field voltage control loop to linearize the exciter control characteristic. This also makes the output independent of supply source variations until supply limitations are reached. These systems utilize a variety of controlled-rectifier designs: full thyristor complements or hybrid bridges
in either series or shunt configurations. The power source may consist of only a potential source, either fed from the machine terminals or from internal windings. Some designs may have compound power sources utilizing both machine potential and current. These power sources are represented as phasor combinations of machine terminal current and voltage and are accommodated by suitable parameters in model Type ST3A which is represented by ExcIEEEST3A.

The class represents IEEE Std 421.5-2005 type ST4B model. This model is a variation of the Type ST3A model, with a proportional plus integral (PI) regulator block replacing the lag-lead regulator characteristic that is in the ST3A model. Both potential and compound source rectifier excitation systems are modeled. The PI regulator blocks have non-windup limits that are represented. The voltage regulator of this model is typically implemented digitally.

The class represents IEEE Std 421.5-2005 type ST7B model. This model is representative of static potential-source excitation systems. In this system, the AVR consists of a PI voltage regulator. A phase lead-lag filter in series allows introduction of a derivative function, typically used with brushless excitation systems. In that case, the regulator is of the PID type. In addition, the terminal voltage channel includes a phase lead-lag filter. The AVR includes the appropriate inputs on its reference for overexcitation limiter (OEL1), underexcitation limiter (UEL), stator current limiter (SCL), and current compensator (DROOP). All these limitations, when they work at voltage reference level, keep the PSS (VS signal from Type PSS1A, PSS2A, or PSS2B) in operation. However, the UEL limitation can also be transferred to the high value (HV) gate acting on the output signal. In addition, the output signal passes through a low value (LV) gate for a ceiling overexcitation limiter (OEL2).

These load models (known also as generic non-linear dynamic (GNLD) load models) can be used in mid-term and long-term voltage stability simulations (i.e., to study voltage collapse), as they can replace a more detailed representation of aggregate load, including induction motors, thermostatically controlled and static loads.

Aggregate induction motor load. This model is used to represent a fraction of an ordinary load as "induction motor load". It allows load that is treated as ordinary constant power in power flow analysis to be represented by an induction motor in dynamic simulation. If Lpp = 0. or Lpp = Lp, or Tppo = 0., only one cage is represented. Magnetic saturation is not modelled. Either a "one-cage" or "two-cage" model of the induction machine can be modelled. Magnetic saturation is not modelled.
This model is intended for representation of aggregations of many motors dispersed through a load represented at a high voltage bus but where there is no information on the characteristics of individual motors.
This model treats a fraction of the constant power part of a load as a motor. During initialisation, the initial power drawn by the motor is set equal to Pfrac times the constant P part of the static load. The remainder of the load is left as static load.
The reactive power demand of the motor is calculated during initialisation as a function of voltage at the load bus. This reactive power demand may be less than or greater than the constant Q component of the load. If the motor's reactive demand is greater than the constant Q component of the load, the model inserts a shunt capacitor at the terminal of the motor to bring its reactive demand down to equal the constant Q reactive load.
If a motor model and a static load model are both present for a load, the motor Pfrac is assumed to be subtracted from the power flow constant P load before the static load model is applied. The remainder of the load, if any, is then represented by the static load model.

The over excitation limiter model is intended to represent the significant features of OELs necessary for some large-scale system studies. It is the result of a pragmatic approach to obtain a model that can be widely applied with attainable data from generator owners. An attempt to include all variations in the functionality of OELs and duplicate how they interact with the rest of the excitation systems would likely result in a level of application insufficient for the studies for which they are intended.

The electrical equations for all variations of the synchronous models are based on the SynchronousEquivalentCircuit diagram for the direct and quadrature axes.
Equations for conversion between Equivalent Circuit and Time Constant Reactance forms:
Xd = Xad + Xl
X’d = Xl + Xad * Xfd / (Xad + Xfd)
X”d = Xl + Xad * Xfd * X1d / (Xad * Xfd + Xad * X1d + Xfd * X1d)
Xq = Xaq + Xl
X’q = Xl + Xaq * X1q / (Xaq+ X1q)
X”q = Xl + Xaq * X1q* X2q / (Xaq * X1q + Xaq * X2q + X1q * X2q)
T’do = (Xad + Xfd) / (omega0 * Rfd)
T”do = (Xad * Xfd + Xad * X1d + Xfd * X1d) / (omega0 * R1d * (Xad + Xfd)
T’qo = (Xaq + X1q) / (omega0 * R1q)
T”qo = (Xaq * X1q + Xaq * X2q + X1q * X2q)/ (omega0 * R2q * (Xaq + X1q)
Same equations using CIM attributes from SynchronousMachineTimeConstantReactance class on left of = sign and SynchronousMachineEquivalentCircuit class on right (except as noted):
xDirectSync = xad + RotatingMachineDynamics.statorLeakageReactance
xDirectTrans = RotatingMachineDynamics.statorLeakageReactance + xad * xfd / (xad + xfd)

xQuadSubtrans = RotatingMachineDynamics.statorLeakageReactance + xaq * x1q* x2q / (xaq * x1q + xaq * x2q + x1q * x2q)
tpdo = (xad + xfd) / (2*pi*nominal frequency * rfd)
tppdo = (xad * xfd + xad * x1d + xfd * x1d) / (2*pi*nominal frequency * r1d * (xad + xfd)

The simplified model represents a synchronous generator as a constant internal voltage behind an impedance (Rs + jXp) as shown in the Simplified diagram.
Since internal voltage is held constant, there is no Efd input and any excitation system model will be ignored. There is also no Ifd output.
This model should not be used for representing a real generator except, perhaps, small generators whose response is insignificant.
The parameters used for the Simplified model include:

Load whose behaviour is described by reference to a standard model or by definition of a user-defined model.
A standard feature of dynamic load behaviour modelling is the ability to associate the same behaviour to multiple energy consumers by means of a single aggregate load definition. Aggregate loads are used to represent all or part of the real and reactive load from one or more loads in the static (power flow) data. This load is usually the aggregation of many individual load devices and the load model is approximate representation of the aggregate response of the load devices to system disturbances. The load model is always applied to individual bus loads (energy consumers) but a single set of load model parameters can used for all loads in the grouping.

Abstract parent class for all synchronous and asynchronous machine standard models.
damping |
0..1 |
Damping torque coefficient (D). A proportionality constant that, when multiplied by the angular velocity of the rotor poles with respect to the magnetic field (frequency), results in the damping torque. This value is often zero when the sources of damping torques (generator damper windings, load damping effects, etc.) are modelled in detail. Typical Value = 0. |

For a generator, this includes the generator plus all other elements (turbine, exciter) on the same shaft and has units of MW*sec. For a motor, it includes the motor plus its mechanical load. Conventional units are per unit on the generator MVA base, usually expressed as MW*second/MVA or just second. This value is used in the accelerating power reference frame for operator training simulator solutions. Typical Value = 3. |

A facility for providing variable and controllable shunt reactive power. The SVC typically consists of a stepdown transformer, filter, thyristor-controlled reactor, and thyristor-switched capacitor arms.
The SVC may operate in fixed MVar output mode or in voltage control mode. When in voltage control mode, the output of the SVC will be proportional to the deviation of voltage at the controlled bus from the voltage setpoint. The SVC characteristic slope defines the proportion. If the voltage at the controlled bus is equal to the voltage setpoint, the SVC MVar output is zero.
