Logging Chapter 6
Logged Parameters
The load factor log consists of 14 records. The first is a header naming the logged
parameters. The second is an active record for the current month. The remaining
records are static and store data for each of the previous 12 months. The monthly
records operate in a circular, or FIFO fashion. On a user-selected day each
month, the current record is pushed into the stack of monthly records and, if the
stack is full, the oldest is deleted. Each record is a structure of REAL elements
containing the following parameters:
• LoadFactor_Record_Number
• LoadFactor_End_Date
• LoadFactor_Elapsed_Time
• Peak_Demand _kW
• Average_Demand_kW
• LoadFactor_kW
• Peak_Demand_kVAR
