Absorbed Diversity Active Power
Absorbed Diversity Active Power is the active power passing through a tag (Supply Tag) that includes the diversity ratio (Duty Circle) assigned to each fed tag i.e. power consumer. It should be noted that a fed tag can be directly or indirectly connected to this Supply Tag.
-
Absorbed Active Power has a unit value of kW.
-
Fed tag Diversity has a unit of ratio.
-
Absorbed Diversity Active Power is the total active power for all equipment tags that are fed directly or indirectly.
-
Absorbed Diversity Active Power is derived from the value of the Utilization for each fed tag. The utilization values are:
-
Continuous
-
Intermittent
-
Standby
-
Spare
-
Equations for Absorbed Active Power attributes are:
Continuous Power = Σ (Absorbed Electrical Power * fed tag Diversity Factor) where fed tag Utilization = Continuous
Intermittent Power = Σ (Absorbed Electrical Power * fed tag Diversity Factor) where fed tag Utilization = Intermittent
Standby Power = Σ (Absorbed Electrical Power * fed tag Diversity Factor) where fed tag Utilization = Standby
Spare Power = Σ (Absorbed Electrical Power * fed tag Diversity Factor) where fed tag Utilization = Spare
Note:
For the above equations, if the tag has the "Include in Power Calculations" flag set
to true, then for that tag the value for the fed tag Diversity Factor = 1.
Absorbed Diversity Reactive Power
Absorbed Diversity Reactive Power is the reactive power passing through a tag (Supply Tag) that includes the diversity ratio (Duty Circle) assigned to each fed tag i.e. power consumer. It should be noted that a fed tag can be directly or indirectly connected to this Supply Tag.
-
Absorbed Reactive Power has a unit value of kVAr.
-
Absorbed Reactive Power can have a positive or negative value. If positive, the associated power factor unit = LAG and if negative, the associated power factor unit = LEAD.
-
Fed tag Diversity has a unit of ratio.
-
Absorbed Diversity Reactive Power is the total reactive power for all equipment tags that are fed directly or indirectly.
Equations for Absorbed Reactive Power attributes are:
Continuous Reactive Power = Σ (Absorbed Reactive Power * fed tag Diversity Factor) where fed tag Utilization = Continuous
Intermittent Reactive Power = Σ (Absorbed Reactive Power * fed tag Diversity Factor) where fed tag Utilization = Intermittent
Standby Reactive Power = Σ (Absorbed Reactive Power * fed tag Diversity Factor) where fed tag Utilization = Standby
Spare Reactive Power = Σ (Absorbed Reactive Power * fed tag Diversity Factor) where fed tag Utilization = Spare
Note:
The above equations are only applicable when power has not passed through a busbar
class tag. For equations for when power has passed through a busbar class tag. Refer
to Busbar Absorbed Diversity Power for further information.
Note:
For the above equations, if the tag has the "Include in Power Calculations" flag set
to true, then for that tag the value for the fed tag Diversity Factor = 1.
Absorbed Diversity Apparent Power
Absorbed Diversity Apparent Power is calculated using Absorbed Diversity Active Power and Absorbed Diversity Reactive Power.
Absorbed Apparent Power has a unit value of kVA.
Equations for Absorbed Apparent Power attributes are:
Continuous Apparent Power = √ (Continuous Power2 + Continuous Reactive Power2)
Intermittent Apparent Power = √ (Intermittent Power2 + Intermittent Reactive Power2)
Standby Apparent Power = √ (Standby Power2 + Standby Reactive Power2)
Spare Apparent Power = √ (Spare Power2 + Spare Reactive Power2)
Absorbed Diversity Power Factor
Absorbed Diversity Power Factor is calculated using Absorbed Diversity Active Power and Absorbed Diversity Apparent Power.
Absorbed Power Factor has a unit value between 0 and 1.
Equations for Absorbed Power Factor attributes are:
Continuous Power Factor = Continuous Power / Continuous Apparent Power
Intermittent Power Factor = Intermittent Power / Intermittent Apparent Power
Standby Power Factor = Standby Power / Standby Apparent Power
Spare Power Factor = Spare Power / Spare Apparent Power
Equations for Absorbed Power Factor Unit attributes are:
If Continuous Reactive Power value is positive then Continuous Power Factor Unit = LAG
If Continuous Reactive Power value is negative then Continuous Power Factor Unit = LEAD
If Continuous Reactive Power value = 0 then Continuous Power Factor Unit = null
If Intermittent Reactive Power value is positive then Intermittent Power Factor Unit = LAG
If Intermittent Reactive Power value is negative then Intermittent Power Factor Unit = LEAD
If Intermittent Reactive Power value = 0 then Intermittent Power Factor Unit = null
If Standby Reactive Power value is positive then Standby Power Factor Unit = LAG
If Standby Reactive Power value is negative then Standby Power Factor Unit = LEAD
If Standby Reactive Power value = 0 then Standby Power Factor Unit = null
If Spare Reactive Power value is positive then Spare Power Factor Unit = LAG
If Spare Reactive Power value is negative then Spare Power Factor Unit = LEAD
If Spare Reactive Power value = 0 then Spare Power Factor Unit = null
Absorbed Diversity Current
Absorbed Diversity Current is calculated using Connection Voltage data (Voltage Type, Project Voltage) and Absorbed Diversity Apparent Power.
Absorbed Diversity Current has a unit value of Amp.
Equations for Absorbed Current attributes are:
If Voltage Type = S then
Continuous Current = (Continuous Apparent Power * 1000) / Project Voltage
If Voltage Type = L then
Continuous Current = (Continuous Apparent Power * 1000) / Project Voltage
If Voltage Type = T, TN then
Continuous Current = (Continuous Apparent Power * 1000) / (Project Voltage * 3)
If Voltage Type = DC then
Continuous Current = (Continuous Power * 1000) / Project Voltage
Note:
In this case Continuous Apparent Power = Continuous Power.
If Voltage Type = S then
Intermittent Current = (Intermittent Apparent Power * 1000) / Project Voltage
If Voltage Type = L then
Intermittent Current = (Intermittent Apparent Power * 1000) / Project Voltage
If Voltage Type = T, TN then
Intermittent Current = (Intermittent Apparent Power * 1000) / (Project Voltage * 3)
If Voltage Type = DC then
Intermittent Current = (Intermittent Power * 1000) / Project Voltage
Note:
In this case Intermittent Apparent Power = Intermittent Power.
If Voltage Type = S then
Standby Current = (Standby Apparent Power * 1000) / Project Voltage
If Voltage Type = L then
Standby Current = (Standby Apparent Power * 1000) / Project Voltage
If Voltage Type = T, TN then
Standby Current = (Standby Apparent Power * 1000) / (Project Voltage * 3)
If Voltage Type = DC then
Standby Current = (Standby Power * 1000) / Project Voltage
Note:
In this case Standby Apparent Power = Standby Power.
If Voltage Type = S then
Spare Current = (Spare Apparent Power * 1000) / Project Voltage
If Voltage Type = L then
Spare Current = (Spare Apparent Power * 1000) / Project Voltage
If Voltage Type = T, TN then
Spare Current = (Spare Apparent Power * 1000) / (Project Voltage * 3)
If Voltage Type = DC then
Spare Current = (Spare Power * 1000) / Project Voltage
Note:
In this case Spare Apparent Power = Spare Power.
