A 2-winding transformer, with a tap changer for variable turns ratio.

The model uses an equivalent circuit assuming the impedance is on the High Voltage Side of the transformer. The model allocates the iron losses and magnetizing susceptance to the primary side

Arguments

  • name::String: Name of the component. Components of the same type (e.g., PowerLoad) must have unique names, but components of different types (e.g., PowerLoad and ACBus) can have the same name
  • available::Bool: Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations
  • active_power_flow::Float64: Initial condition of active power flow through the transformer (MW)
  • reactive_power_flow::Float64: Initial condition of reactive power flow through the transformer (MVAR)
  • arc::Arc: An Arc defining this transformer from a bus to another bus
  • r::Float64: Resistance in p.u. (SYSTEM_BASE), validation range: (-2, 2)
  • x::Float64: Reactance in p.u. (SYSTEM_BASE), validation range: (-2, 4)
  • primary_shunt::Float64: Shunt reactance in p.u. (SYSTEM_BASE), validation range: (0, 2)
  • tap::Float64: Normalized tap changer position for voltage control, varying between 0 and 2, with 1 centered at the nominal voltage, validation range: (0, 2)
  • rating::Union{Nothing, Float64}: Thermal rating (MVA). Flow through the transformer must be between -rating. When defining a transformer before it is attached to a System, rating must be in pu (SYSTEM_BASE) using the base power of the System it will be attached to, validation range: (0, nothing)
  • services::Vector{Service}: (default: Device[]) Services that this device contributes to
  • ext::Dict{String, Any}: (default: Dict{String, Any}()) An extra dictionary for users to add metadata that are not used in simulation, such as latitude and longitude.
  • internal::InfrastructureSystemsInternal: (Do not modify.) PowerSystems.jl internal reference
