Concrete Classes

An attribute from the associated PowerSystemResource is used. This is like reflection into the UML model as one must name the paramter the same as the CIM name of the desired attribute. Such parameters are not important for completely standard models as the relation to the CIM attributes is fixed. This object is required for user defined models that use attributes already existing on the PowerSystemResource or its derived classes. Using this class avoids creating new paramter instances (with values) when we already have the values as class attributes of the associated PowerSystemResource. Standard block models might optinally use objects of this class to convey information about the internals of the standard block.

Native Members

attributeName	0..1	String		The name of the attribute in the information model. This could be any attribute of the derived class of the power system resource for which the block is intended to be used. For example, if the one were using the xxx attribute from Generator class, one would specifiy this attribute as "xxx". This would also limit the block to only those classes which have an "xxx" attribute. This attribute could be replaced by using the inherited IdentifiedObject.name value for the purpose described above.

ExcAC3A

IEEE (1992/2005) 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.

ExcAC4A

IEEE (1992/2005) AC4A Model

The Type AC4A alternator-supplied controlled-rectifier excitation system 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.

ExcAC5A

IEEE (1992/2005) AC5A Model

The model designated as Type AC5A, is 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.

ExcAC7B

IEEE (2005) AC7B Model

These excitation systems consist of an ac alternator with either stationary or rotating rectifiers to produce the
dc field requirements. Upgrades to earlier ac excitation systems, which replace only the controls but retain
the ac alternator and diode rectifier bridge, have resulted in this new model. Some of the features of this excitation system include a high bandwidth inner loop regulating generator field voltage
or exciter current (KF2, KF1), a fast exciter current limit, VFEMAX, to protect the field of the ac alternator, and
the PID generator voltage regulator (AVR). An alternative rate feedback loop (KF, TF) is provided for
stabilization if the AVR does not include a derivative term. If a PSS control is supplied, the Type PSS2B or
PSS3B models are appropriate.

ExcAC8B

IEEE (2005) AC8B Model

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 x VRMAX and VT x VRMIN.

ExcDC3A

IEEE (1992/2005) DC3A Model

The Type DC3A model is used to 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.

These excitation systems utilize a field-controlled dc commutator exciter with a continuously acting voltage

This excitation system typically includes a proportional, integral, and differential (PID) generator voltage regulator (AVR). An alternative rate feedback loop (kf, tf) for stabilization is also shown in the model if the AVR does not include a derivative term. If a PSS control is supplied, the appropriate model is the Type PSS2B model.

ExcST1A

IEEE (1992/2005) ST1A Model

The computer model of the Type ST1A potential-source controlled-rectifier excitation system represents systems in which excitation power is supplied through a transformer from the generator terminals (or the unit's auxiliary bus) and is regulated by a controlled rectifier. The maximum exciter voltage available from such systems is directly related to the generator terminal voltage.

ExcST3A

IEEE (1992/2005) 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 the model Type ST3A.

ExcST7B

IEEE (2005) ST7B Model

The model ST7B 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).

LoadMotor

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. Either a "one-cage" or "two-cage" model of the induction machine can be modeled. Magnetic saturation is not modeled.

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.

MetaBlock

A block is a meta-data representation of a control block. It has an external interface and an optinal internal interface. Blocks internals can be ommitted if the block is well understood by both exchange parties. When well understood by both partice the block can be treated as a primitive block. All dynamic models must be defined to the level of primtive blocks in order for the model to be consumed and used for dynamic simulation. Examples of primitive blocks include a well known IEEE exciter model, a summation block, or an integrator block.

AggregateLoad

Aggregate loads are used to represent all or part of the real and reactive load from a load in the static (power flow) data. This load is usually the aggregation of many individual load devices. The load models are approximate representation of the aggregate response of the load devices to system disturbances.

Models of loads for dynamic analysis may themselves be either static or dynamic. A static load model represents the sensitivity of the real and reactive power consumed by the load to the amplitude and frequency of the bus voltage. A dynamic load model can used to represent the aggregate response of the motor components of the load.

Large industrial motors or groups of similar motors may be represented by individual motor models (synchronous or asynchronous) which are usually represented as generators with negative Pgen in the static (power flow) data.

Measurement

Meas

A Measurement represents any measured, calculated or non-measured non-calculated quantity. Any piece of equipment may contain Measurements, e.g. a substation may have temperature measurements and door open indications, a transformer may have oil temperature and tank pressure measurements, a bay may contain a number of power flow measurements and a Breaker may contain a switch status measurement.
The PSR - Measurement association is intended to capture this use of Measurement and is included in the naming hierarchy based on EquipmentContainer. The naming hierarchy typically has Measurements as leafs, e.g. Substation-VoltageLevel-Bay-Switch-Measurement.
Some Measurements represent quantities related to a particular sensor location in the network, e.g. a voltage transformer (PT) at a busbar or a current transformer (CT) at the bar between a breaker and an isolator. The sensing position is not captured in the PSR - Measurement association. Instead it is captured by the Measurement - Terminal association that is used to define the sensing location in the network topology. The location is defined by the connection of the Terminal to ConductingEquipment.
If both a Terminal and PSR are associated, and the PSR is of type ConductingEquipment, the associated Terminal should belong to that ConductingEquipment instance.
When the sensor location is needed both Measurement-PSR and Measurement-Terminal are used. The Measurement-Terminal association is never used alone.

damping	1..1	Simple_Float	Damping torque coefficient, 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 modeled in detail.
inertia	1..1	Seconds	Inertia constant of generator or motor and mechanical load. Must be greater than zero. This is the specification for the stored energy in the rotating mass when operating at rated speed. 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.
parametersFormType	1..1	ParametersFormType
saturationFactor	1..1	Simple_Float	Saturation factor at rated terminal voltage. Should be greather than or equal to zero.
saturationFactor120	1..1	Simple_Float	Saturation factor at 120% of rated terminal voltage. Should be greater than or equal to the saturation factor at rated terminal voltage.
statorLeakageReactance	1..1	Reactance	Stator leakage reactance. Should be greater than or equal to 0.
statorResistance	1..1	Resistance	Stator (armature) resistance. Should be greather than or equal to zero. Equivalent resistance when used for GenEquiv model.
