class cimpy.cgmes_v2_4_15.ExcIEEEST3A.ExcIEEEST3A(vimax=0.0, vimin=0.0, ka=0.0, ta=0, tb=0, tc=0, vrmax=0.0, vrmin=0.0, km=0.0, tm=0, vmmax=0.0, vmmin=0.0, kg=0.0, kp=0.0, thetap=0.0, ki=0.0, kc=0.0, xl=0.0, vbmax=0.0, vgmax=0.0, *args, **kw_args)

The class represents IEEE Std 421.5-2005 type 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 model Type ST3A which is represented by ExcIEEEST3A. Reference: IEEE Standard 421.5-2005 Section 7.3.

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: ‘’
