A phase-shifting transformer regulating the phase angle between two buses to control active power flow in the system.

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 pu (SYSTEM_BASE), validation range: (0, 4)
  • x::Float64: Reactance in pu (SYSTEM_BASE), validation range: (-2, 4)
  • primary_shunt::Complex{Float64}: Primary shunt admittance in pu (SYSTEM_BASE)
  • 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)
  • α::Float64: Initial condition of phase shift (radians) between the from and to buses , validation range: (-1.571, 1.571)
  • rating::Union{Nothing, Float64}: Thermal rating (MVA). Flow through the transformer must be between -rating and 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)
  • base_power::Float64: Base power (MVA) for per unitization, validation range: (0.0001, nothing)
  • base_voltage_primary::Union{Nothing, Float64}: (default: get_base_voltage(get_from(arc))) Primary base voltage in kV, validation range: (0, nothing)
  • base_voltage_secondary::Union{Nothing, Float64}: (default: get_base_voltage(get_to(arc))) Secondary base voltage in kV, validation range: (0, nothing)
  • rating_b::Union{Nothing, Float64}: (default: nothing) Second current rating; entered in MVA.
  • rating_c::Union{Nothing, Float64}: (default: nothing) Third current rating; entered in MVA.
  • phase_angle_limits::MinMax: (default: (min=-3.1416, max=3.1416)) Minimum and maximum phase angle limits (radians)
  • control_objective::TransformerControlObjective: (default: TransformerControlObjective.UNDEFINED) Control objective for the tap changer for power flow calculations. See TransformerControlObjective
  • 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.
  • internal::InfrastructureSystemsInternal: (Do not modify.) PowerSystems.jl internal reference
