class cimpy.cgmes_v2_4_15.ExcSCRX.ExcSCRX(cswitch=False, emax=0.0, emin=0.0, k=0.0, rcrfd=0.0, tatb=0.0, tb=0.0, te=0.0, *args, **kw_args)

Simple excitation system model representing generic characteristics of many excitation systems; intended for use where negative field current may be a problem.

cswitch:

Power source switch (Cswitch). true = fixed voltage of 1.0 PU false = generator terminal voltage. Default: False

emax:

Maximum field voltage output (Emax). Typical Value = 5. Default: 0.0

emin:

Minimum field voltage output (Emin). Typical Value = 0. Default: 0.0

k:

Gain (K) (>0). Typical Value = 200. Default: 0.0

rcrfd:

Rc/Rfd - ratio of field discharge resistance to field winding resistance (RcRfd). Typical Value = 0. Default: 0.0

tatb:

Ta/Tb - gain reduction ratio of lag-lead element (TaTb). The parameter Ta is not defined explicitly. Typical Value = 0.1. Default: 0.0

tb:

Denominator time constant of lag-lead block (Tb). Typical Value = 10. Default: 0.0

te:

Time constant of gain block (Te) (>0). Typical Value = 0.02. Default: 0.0

Documentation of parent class ExcitationSystemDynamics:

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

DiscontinuousExcitationControlDynamics:

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

OverexcitationLimiterDynamics:

Overexcitation limiter 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

PFVArControllerType2Dynamics:

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

PowerSystemStabilizerDynamics:

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

SynchronousMachineDynamics:

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

UnderexcitationLimiterDynamics:

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

VoltageCompensatorDynamics:

Voltage compensator 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”

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: ‘’

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: ‘’

shortName:

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