This is modified IEEE DC3A direct current commutator exciters with speed input, and death band. DC old type 4.
- trh
Rheostat travel time (Trh). Typical Value = 20. Default: 0
- ks
Coefficient to allow different usage of the model-speed coefficient (Ks). Typical Value = 0. Default: 0.0
- kr
Death band (Kr). If Kr is not zero, the voltage regulator input changes at a constant rate if Verr > Kr or Verr < -Kr as per the IEEE (1968) Type 4 model. If Kr is zero, the error signal drives the voltage regulator continuously as per the IEEE (1980) DC3 and IEEE (1992, 2005) DC3A models. Typical Value = 0. Default: 0.0
- kv
Fast raise/lower contact setting (Kv). Typical Value = 0.05. Default: 0.0
- vrmax
Maximum voltage regulator output (Vrmax). Typical Value = 5. Default: 0.0
- vrmin
Minimum voltage regulator output (Vrmin). Typical Value = 0. Default: 0.0
- te
Exciter time constant, integration rate associated with exciter control (Te). Typical Value = 1.83. Default: 0
- ke
Exciter constant related to self-excited field (Ke). Typical Value = 1. Default: 0.0
- efd1
Exciter voltage at which exciter saturation is defined (Efd1). Typical Value = 2.6. Default: 0.0
- seefd1
Exciter saturation function value at the corresponding exciter voltage, Efd1 (Se[Eefd1]). Typical Value = 0.1. Default: 0.0
- efd2
Exciter voltage at which exciter saturation is defined (Efd2). Typical Value = 3.45. Default: 0.0
- seefd2
Exciter saturation function value at the corresponding exciter voltage, Efd2 (Se[Efd2]). Typical Value = 0.35. 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 not applied to integrator output. Typical Value = true. Default: False
- edfmax
Maximum voltage exciter output limiter (Efdmax). Typical Value = 99. Default: 0.0
- efdmin
Minimum voltage exciter output limiter (Efdmin). Typical Value = -99. Default: 0.0
- efdlim
(Efdlim). true = exciter output limiter is active false = exciter output limiter not active. 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
- PFVArControllerType2Dynamics
Power Factor or VAr controller Type II model associated with this excitation system model. Default: None
- OverexcitationLimiterDynamics
Overexcitation 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: ‘’
