Circuit UF Load Shed
The following is an example of how to apply UF Load Shed logic at the circuit or feeder level. The logic
can be applied in any number of ways including stand alone, to other preprogrammed schemes or
completely customized by the user. Using BESTCOMS to modify and add to the logic is, not only quick
and easy, but minimizes Input/Output "name" and "state" label changes. In this example, start with a
renamed version of the BESTCOMS 0C-W-79 logic scheme, Section 8, Application, modified as follows:
SN-IN1=L_OR_S_RES,CLOSE,OPEN (Local or SCADA Restore)
Add the following Circuit UF logic to the modified OC-W-79 Logic Scheme:
SL-62=2,VO10,0 (optional target reset)
SL-79=1,VO8,/IN1,VO14,0
SL-81=1,O
SL-181=1,O
SL-281=1,VO14
SL-381=1,VO14
SL-VO1=VO13
SL-VO2=79C
SL-VO3=/VO13
SL-VO6=81T*181T
SL-VO7=281T*381T
SL-VO8=VO6
SL-VO10=/VO6*IN1*IN3*VO7
SL-VO13=VO6+VO14
SL-VO14=/VO10*VO13
Add +81T+181T to BUS SG-TRIG
Replace the ,0 with ,62 at the end of BUS SG-TARG
The resulting OC-UF-79 setting logic is as follows:
SL-50TP=1,79SCB; SL-50TN=1,79SCB+/IN4; SL-50TQ=1,79SCB+/IN4
SL-150TP=1,0; SL-150TN=1,0; SL-150TQ=1,0
SL-51P=1,0
SL-51N=1,/IN4
SL-51Q=1,/IN4
SL-151N=0,0
SL-27P=0,0
SL-59P=0,0; SL-59X=0,0
SL-47=0,0
