Syntax
PDLSET(area,exceed,set1,time1,...,set7,time7)
area | Meter area. - In order for the program to operate correctly, the same numeric value must be used for the meter area parameter in the PDLDPG, PDLMTR, and PDLSET statements. - This parameter is an integer. |
exceed | DO point which is turned ON if the actual floating window peak exceeded the setpoint at any time during the preceding interval. This point is reset to OFF at the end of each setpoint interval. |
set1 through set7 | Demand setpoint (in kilowatts) that is not to be exceeded. - This parameter can be a decimal, integer, point name, or a local variable. |
time1 through time7 | The time at which the corresponding setpoint ends. - This parameter is usually entered as a clock time in military format (7:30 p.m. = 19:30). It can also be entered as a decimal, integer, or a local variable. - Times must be in ascending order. |
Use
The PDLSET command designates the peak demand limiting (PDL) levels and ensures that the PDL levels for a meter area are not exceeded during the time those setpoints are in effect.
Demand predictions made by the PDLMTR command are compared with the appropriate setpoints defined by the PDLSET command. The PDLSET command then determines the number of kilowatts (if any) that must be shed or restored for the meter area.
Example

101 C PDLSET COMMAND INFORMATION:
102 C
103 C - THIS COMMAND CONTROLS METER AREA 1.
104 C - THE VIRTUAL LDO POINT WHICH WILL
105 C TOGGLE ON AND OFF AT THE END OF
106 C THE SET POINT INTERVALS WHEN THE
107 C SET POINT WAS EXCEEDED IS
108 C CALLED PEAKEX.
109 C - PDLST1 SET POINT ENDS AT 11:00 A.M.
110 C - PDLST2 SET POINT ENDS AT 4:30 P.M.
111 C
120 PDLSET(1,PEAKEX,PDLST1,11:00,PDLST2,16:30)
Notes
The PDLSET command requires at least two setpoint/time definitions for each day in order to generate reports.
