Compute the losses incurred at the power conversion station. These losses are comprised of parasitic loads for inverter cooling, tracker actuator, and auxiliary loads such as the data acquisition system, lighting, etc.

Algorithm

Note the following preconditions before performing the calculations:

a.) The tracker actuator loss P_L,Tracker is only applied during daylight hours at Arrays which host one or more tracker DC Fields.

b.) The inverter cooling load loss P_L,Cooling is only applied during daylight hours when the inverter is operating.

c.) The auxiliary loss P_L,DAS is present for all hours of the day.

 

1.) Find the power at the input terminal of the Array transformer.

2.) Find the power dissipated in the Array transformer.

3.) Find the power output by the power conversion station.
