Class SynchronousMachine

Initialises a new 'SynchronousMachine' instance.

Parameters:

• ratedS - Nameplate apparent power rating for the unit
• r2 - Negative sequence resistance.
• r0 - Zero sequence resistance of the synchronous machine.
• manualToAVR - Time delay required when switching from Manual to Automatic Voltage Regulation. This value is used in the accelerating power reference frame for powerflow solutions
• qPercent - Percent of the coordinated reactive control that comes from this machine.
• coolantCondition - Temperature or pressure of coolant medium
• condenserP - Active power consumed when in condenser mode operation.
• xQuadTrans - Quadrature-axis transient reactance, also known as X'q.
• xQuadSubtrans - Quadrature-axis subtransient reactance, also known as X'q.
• xQuadSync - Quadrature-axis synchronous reactance (Xq) , the ratio of the component of reactive armature voltage, due to the quadrature-axis component of armature current, to this component of current, under steady state conditions and at rated frequency.
• xDirectSync - Direct-axis synchronous reactance. The quotient of a sustained value of that AC component of armature voltage that is produced by the total direct-axis flux due to direct-axis armature current and the value of the AC component of this current, the machine running at rated speed. (Xd)
• minQ - Minimum reactive power limit for the unit.
• aVRToManualLag - Time delay required when switching from Automatic Voltage Regulation (AVR) to Manual for a lagging MVAr violation.
• damping - Damping torque coefficient, a proportionality constant that, when multiplied by the angular velocity of the rotor poles with respect to the magnetic field (frequency), results in the damping torque.
• operatingMode - Current mode of operation. Values are: "condenser", "generator"
• xDirectSubtrans - Direct-axis subtransient reactance, also known as X'd.

• minU - Minimum voltage limit for the unit.
• maxQ - Maximum reactive power limit. This is the maximum (nameplate) limit for the unit.
• referencePriority - Priority of unit for reference bus selection. 0 = don t care (default) 1 = highest priority. 2 is less than 1 and so on.
• maxU - Maximum voltage limit for the unit.
• xDirectTrans - Direct-axis transient reactance, also known as X'd.
• inertia - The energy stored in the rotor when operating at rated speed. This value is used in the accelerating power reference frame for operator training simulator solutions.
• baseQ - Default base reactive power value. This value represents the initial reactive power that can be used by any application function.
• type - Modes that this synchronous machine can operate in. Values are: "condenser", "generator_or_condenser", "generator"

• GeneratingUnit - A synchronous machine may operate as a generator and as such becomes a member of a generating unit
• ReactiveCapabilityCurves - All available Reactive capability curves for this SynchronousMachine.
• HydroPump - The synchronous machine drives the turbine which moves the water from a low elevation to a higher elevation. The direction of machine rotation for pumping may or may not be the same as for generating.
• InitialReactiveCapabilityCurve - The default ReactiveCapabilityCurve for use by a SynchronousMachine
