cimpy.cgmes_v2_4_15.ExcIEEEST2A module

class cimpy.cgmes_v2_4_15.ExcIEEEST2A.ExcIEEEST2A(efdmax=0.0, ka=0.0, kc=0.0, ke=0.0, kf=0.0, ki=0.0, kp=0.0, ta=0.0, te=0.0, tf=0.0, uelin=False, vrmax=0.0, vrmin=0.0, *args, **kw_args)

The class represents IEEE Std 421.5-2005 type ST2A model. Some static systems utilize both current and voltage sources (generator terminal quantities) to comprise the power source. The regulator controls the exciter output through controlled saturation of the power transformer components. These compound-source rectifier excitation systems are designated Type ST2A and are represented by ExcIEEEST2A. Reference: IEEE Standard 421.5-2005 Section 7.2.

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: ‘’
