MotorLoad

Package: PowerOperationsOpenAPIModels · Source: Operations/StaticInjection/MotorLoad.json

An induction-motor static load, representing the steady-state power draw of motor-driven demand.

This load models the aggregate real and reactive power consumed by induction motors, along with the motor technology parameters that characterize their electrical behavior. For a simple constant-power load with no motor characteristics, see PowerLoad. For voltage-dependent ZIP loads used in dynamics modeling, see StandardLoad.

Properties

Property	Type	Required	Unit	Description
id	integer	yes	—	Unique integer identifier for this component.
name	string	yes	—	Name of the component. Components of the same type (e.g., MotorLoad) must have unique names, but components of different types (e.g., MotorLoad and ACBus) can have the same name.
available	boolean	yes	—	Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations.
bus	integer	yes	—	ID of the bus that this component is connected to.
active_power	number	yes	MW / pu (by power_units)	Initial steady-state active power demand. A positive value indicates power consumption. Units: per power_units — NATURAL_UNITS: MW, COMPONENT_BASE: pu .
reactive_power	number	yes	MVAr / pu (by power_units)	Initial steady-state reactive power demand. A positive value indicates reactive power consumption. Units: per power_units — NATURAL_UNITS: MVAr, COMPONENT_BASE: pu .
base_power	number	yes	MVA	Base power of the unit for per unitization. Units: MVA.
power_units	string (UnitSystem)	yes	—	Unit basis for this component’s power-family fields (active/reactive/apparent power, ratings, limits, ramp rates). COMPONENT_BASE: per unit on this component’s own base_power. NATURAL_UNITS: the field’s physical unit.
rating	number	yes	MVA / pu (by power_units)	Maximum AC side output power rating of the unit. Not to be confused with base_power. Units: per power_units — NATURAL_UNITS: MVA, COMPONENT_BASE: pu .
max_active_power	number	yes	MW / pu (by power_units)	Maximum active power that this load can demand. Units: per power_units — NATURAL_UNITS: MW, COMPONENT_BASE: pu .
reactive_power_limits	MinMax	—	MVAr / pu (by power_units)	Minimum and maximum reactive power limits. Set to null if not applicable. Units: per power_units — NATURAL_UNITS: MVAr, COMPONENT_BASE: pu .
motor_technology	string	—	—	AC Motor type.
dynamic_injector	integer or null	—	—	ID of the corresponding dynamic injection device, if any.
