Modified IEEE DC2A direct current commutator exciters 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

Voltage regulator gain (Ka). Typical Value = 300. Default: 0.0

ks

Coefficient to allow different usage of the model-speed coefficient (Ks). Typical Value = 0. Default: 0.0

ta

Voltage regulator time constant (Ta). Typical Value = 0.01. Default: 0

tb

Voltage regulator time constant (Tb). Typical Value = 0. Default: 0

tc

Voltage regulator time constant (Tc). Typical Value = 0. Default: 0

vrmax

Maximum voltage regulator output (Vrmax). Typical Value = 4.95. Default: 0.0

vrmin

Minimum voltage regulator output (Vrmin). Typical Value = -4.9. Default: 0.0

ke

Exciter constant related to self-excited field (Ke). If Ke is entered as zero, the model calculates an effective value of Ke such that the initial condition value of Vr is zero. The zero value of Ke is not changed. If Ke is entered as non-zero, its value is used directly, without change. Typical Value = 1. Default: 0.0

te

Exciter time constant, integration rate associated with exciter control (Te). Typical Value = 1.33. Default: 0

kf

Excitation control system stabilizer gain (Kf). Typical Value = 0.1. Default: 0.0

tf

Excitation control system stabilizer time constant (Tf). Typical Value = 0.675. Default: 0

tf1

Excitation control system stabilizer time constant (Tf1). Typical Value = 0. Default: 0

efd1

Exciter voltage at which exciter saturation is defined (Efd1). Typical Value = 3.05. Default: 0.0

seefd1

Exciter saturation function value at the corresponding exciter voltage, Efd1 (Se[Eefd1]). Typical Value = 0.279. Default: 0.0

efd2

Exciter voltage at which exciter saturation is defined (Efd2). Typical Value = 2.29. Default: 0.0

seefd2

Exciter saturation function value at the corresponding exciter voltage, Efd2 (Se[Efd2]). Typical Value = 0.117. Default: 0.0

exclim

(exclim). 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. Default: False

vtlim

(Vtlim). true = limiter at the block [Ka/(1+sTa)] is dependent on Vt false = limiter at the block is not dependent on Vt. Typical Value = true. Default: False

Documentation of parent class ExcitationSystemDynamics:

Excitation system function block whose behavior is described by reference to a standard model

SynchronousMachineDynamics

Synchronous machine model with which this excitation system model is associated. Default: None

PowerSystemStabilizerDynamics

Power system stabilizer model associated with this excitation system model. Default: None

PFVArControllerType1Dynamics

Power Factor or VAr controller Type I model associated with this excitation system model. Default: None

VoltageCompensatorDynamics

Voltage compensator model associated with this excitation system model. Default: None

DiscontinuousExcitationControlDynamics

Discontinuous excitation control model associated with this excitation system model. Default: None

UnderexcitationLimiterDynamics

Undrexcitation limiter model associated with this excitation system model. Default: None

Documentation of parent class DynamicsFunctionBlock:

Abstract parent class for all Dynamics function blocks.

enabled

Function block used indicator. true = use of function block is enabled false = use of function block is disabled. Default: False

Documentation of parent class IdentifiedObject:

This is a root class to provide common identification for all classes needing identification and naming attributes.

DiagramObjects

The domain object to which this diagram object is associated. Default: “list”

mRID

Master resource identifier issued by a model authority. The mRID is globally unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended. For CIMXML data files in RDF syntax conforming to IEC 61970-552 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’

name

The name is any free human readable and possibly non unique text naming the object. Default: ‘’

description

The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy. Default: ‘’

energyIdentCodeEic

The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. References: Default: ‘’

shortName

The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
