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.
