Class GeneratingUnit

Initialises a new 'GeneratingUnit' instance.

Parameters:

• ratedGrossMinP - The gross rated minimum generation level which the unit can safely operate at while delivering power to the transmission grid
• efficiency - The efficiency of the unit in converting mechanical energy, from the prime mover, into electrical energy.
• stepChange
• ratedNetMaxP - The net rated maximum capacity determined by subtracting the auxiliary power used to operate the internal plant machinery from the rated gross maximum capacity
• tieLinePF - Generating unit economic participation factor
• dispReserveFlag
• controlPulseHigh - Pulse high limit which is the largest control pulse that the unit can respond to
• startupTime - Time it takes to get the unit on-line, from the time that the prime mover mechanical power is applied
• maxOperatingP - This is the maximum operating active power limit the dispatcher can enter for this unit
• genControlSource - The source of controls for a generating unit. Values are: "plantControl", "offAGC", "unavailable", "onAGC"
• normalPF - Generating unit economic participation factor
• initialP - Default Initial active power which is used to store a powerflow result for the initial active power for this unit in this network configuration
• spinReserveRamp
• allocSpinResP - The planned unused capacity (spinning reserve) which can be used to support emergency load
• minEconomicP - Low economic active power limit that must be greater than or equal to the minimum operating active power limit
• longPF - Generating unit economic participation factor
• nominalP - The nominal power of the generating unit. Used to give precise meaning to percentage based attributes such as the govenor speed change droop (govenorSCD attribute).
• controlResponseRate - Unit response rate which specifies the active power change for a control pulse of one second in the most responsive loading level of the unit.
• ratedGrossMaxP - The unit's gross rated maximum capacity (Book Value).
• penaltyFactor - Defined as: 1 / ( 1 - Incremental Transmission Loss); with the Incremental Transmission Loss expressed as a plus or minus value. The typical range of penalty factors is (0.9 to 1.1).
• fastStartFlag
• minimumOffTime - Minimum time interval between unit shutdown and startup
• shortPF - Generating unit economic participation factor
• governorMPL - Governor Motor Position Limit
• energyMinP
• fuelPriority
• maxEconomicP - Maximum high economic active power limit, that should not exceed the maximum operating active power limit
• autoCntrlMarginP - The planned unused capacity which can be used to support automatic control overruns.
• highControlLimit - High limit for secondary (AGC) control
• modelDetail - Detail level of the generator model data
• controlPulseLow - Pulse low limit which is the smallest control pulse that the unit can respond to
• raiseRampRate
• controlDeadband - Unit control error deadband. When a unit's desired active power change is less than this deadband, then no control pulses will be sent to the unit.
• baseP - For dispatchable units, this value represents the economic active power basepoint, for units that are not dispatchable, this value represents the fixed generation value. The value must be between the operating low and high limits.
• startupCost - The initial startup cost incurred for each start of the GeneratingUnit.
• variableCost - The variable cost component of production per unit of ActivePower.
• genOperatingMode - Operating mode for secondary control. Values are: "MRN", "EDC", "LFC", "fixed", "REG", "AGC", "manual", "off"
• lowerRampRate
• minOperatingP - This is the minimum operating active power limit the dispatcher can enter for this unit.
• lowControlLimit - Low limit for secondary (AGC) control
• maximumAllowableSpinningReserve - Maximum allowable spinning reserve. Spinning reserve will never be considered greater than this value regardless of the current operating point.
• genControlMode - The unit control mode. Values are: "setpoint", "pulse"
• governorSCD - Governor Speed Changer Droop. This is the change in generator power output divided by the change in frequency normalized by the nominal power of the generator and the nominal frequency and expressed in percent and negated. A positive value of speed change droop provides additional generator output upon a drop in frequency.
• ControlAreaGeneratingUnit - ControlArea specifications for this generating unit.
• SynchronousMachines - A synchronous machine may operate as a generator and as such becomes a member of a generating unit
• GenUnitOpSchedule - A generating unit may have an operating schedule, indicating the planned operation of the unit
• GrossToNetActivePowerCurves - A generating unit may have a gross active power to net active power curve, describing the losses and auxiliary power requirements of the unit
• GenUnitOpCostCurves - A generating unit may have one or more cost curves, depending upon fuel mixture and fuel cost.
