The class represents IEEE Std 421.5-2005 type AC8B model. This model represents a PID voltage regulator with either a brushless exciter or dc exciter. The AVR in this model consists of PID control, with separate constants for the proportional (), integral (), and derivative () gains. The representation of the brushless exciter (, , , , ) is similar to the model Type AC2A. The Type AC8B model can be used to represent static voltage regulators applied to brushless excitation systems. Digitally based voltage regulators feeding dc rotating main exciters can be represented with the AC Type AC8B model with the parameters and set to 0. For thyristor power stages fed from the generator terminals, the limits and should be a function of terminal voltage: * and * . Reference: IEEE Standard 421.5-2005 Section 6.8.

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: ‘’
