Detailed Description

A PowerTransformerEnd is associated with each Terminal of a PowerTransformer. The impedance values r, r0, x, and x0 of a PowerTransformerEnd represents a star equivalent as follows 1) for a two Terminal PowerTransformer the high voltage (TransformerEnd. endNumber=1) PowerTransformerEnd has non zero values on r, r0, x, and x0 while the low voltage (TransformerEnd.endNumber=0) PowerTransformerEnd has zero values for r, r0, x, and x0. 2) for a three Terminal PowerTransformer the three PowerTransformerEnds represents a star equivalent with each leg in the star represented by r, r0, x, and x0 values. 3) For a three Terminal transformer each PowerTransformerEnd shall have g, g0, b and b0 values corresponding the no load losses distributed on the three PowerTransformerEnds. The total no load loss shunt impedances may also be placed at one of the PowerTransformerEnds, preferably the end numbered 1, having the shunt values on end 1 is the preferred way. 4) for a PowerTransformer with more than three Terminals the PowerTransformerEnd impedance values cannot be used. Instead use the TransformerMeshImpedance or split the transformer into multiple PowerTransformers.

Member Data Documentation

b

IEC61970::Base::Domain::Susceptance IEC61970::Base::Wires::PowerTransformerEnd::b

Magnetizing branch susceptance (B mag). The value can be positive or negative.

b0

IEC61970::Base::Domain::Susceptance IEC61970::Base::Wires::PowerTransformerEnd::b0

Zero sequence magnetizing branch susceptance.

connectionKind

IEC61970::Base::Wires::WindingConnection IEC61970::Base::Wires::PowerTransformerEnd::connectionKind = IEC61970::Base::Wires::WindingConnection::_undef

Kind of connection.

g

IEC61970::Base::Domain::Conductance IEC61970::Base::Wires::PowerTransformerEnd::g

Magnetizing branch conductance.

g0

IEC61970::Base::Domain::Conductance IEC61970::Base::Wires::PowerTransformerEnd::g0

Zero sequence magnetizing branch conductance (star-model).

phaseAngleClock

IEC61970::Base::Domain::Integer IEC61970::Base::Wires::PowerTransformerEnd::phaseAngleClock

Terminal voltage phase angle displacement where 360 degrees are represented with clock hours. The valid values are 0 to 11. For example, for the secondary side end of a transformer with vector group code of 'Dyn11', specify the connection kind as wye with neutral and specify the phase angle of the clock as

1. The clock value of the transformer end number specified as 1, is assumed to be zero. Note the transformer end number is not assumed to be the same as the terminal sequence number.

r

IEC61970::Base::Domain::Resistance IEC61970::Base::Wires::PowerTransformerEnd::r

Resistance (star-model) of the transformer end. The attribute shall be equal or greater than zero for non-equivalent transformers.

r0

IEC61970::Base::Domain::Resistance IEC61970::Base::Wires::PowerTransformerEnd::r0

Zero sequence series resistance (star-model) of the transformer end.

ratedS

IEC61970::Base::Domain::ApparentPower IEC61970::Base::Wires::PowerTransformerEnd::ratedS

Normal apparent power rating. The attribute shall be a positive value. For a two-winding transformer the values for the high and low voltage sides shall be identical.

ratedU

IEC61970::Base::Domain::Voltage IEC61970::Base::Wires::PowerTransformerEnd::ratedU

Rated voltage: phase-phase for three-phase windings, and either phase-phase or phase-neutral for single-phase windings. A high voltage side, as given by TransformerEnd.endNumber, shall have a ratedU that is greater or equal than ratedU for the lower voltage sides.

x

IEC61970::Base::Domain::Reactance IEC61970::Base::Wires::PowerTransformerEnd::x

Positive sequence series reactance (star-model) of the transformer end.

x0

IEC61970::Base::Domain::Reactance IEC61970::Base::Wires::PowerTransformerEnd::x0

Zero sequence series reactance of the transformer end.
