Detailed Description

Describes a tap changer with a linear relation between the tap step and the phase angle difference across the transformer. This is a mathematical model that is an approximation of a real phase tap changer. The phase angle is computed as stepPhaseShitfIncrement times the tap position. The secondary side voltage magnitude is the same as at the primary side.

Member Data Documentation

IEC61970::Base::Domain::AngleDegrees IEC61970::Base::Wires::PhaseTapChangerLinear::stepPhaseShiftIncrement

Phase shift per step position. A positive value indicates a positive phase shift from the winding where the tap is located to the other winding (for a two- winding transformer). The actual phase shift increment might be more accurately computed from the symmetrical or asymmetrical models or a tap step table lookup if those are available.

IEC61970::Base::Domain::Reactance IEC61970::Base::Wires::PhaseTapChangerLinear::xMax

The reactance depend on the tap position according to a "u" shaped curve. The maximum reactance (xMax) appear at the low and high tap positions.

IEC61970::Base::Domain::Reactance IEC61970::Base::Wires::PhaseTapChangerLinear::xMin

The reactance depend on the tap position according to a "u" shaped curve. The minimum reactance (xMin) appear at the mid tap position.
