First, define two LOAD-ASSIGNMENT instructions, one for winter andone for summer.WINTER-CHLR = LOAD-ASSIGNMENTTYPE = COOLINGLOAD-RANGE = 10PLANT-EQUIPMENT = DBUNNUMBER = 1 ..= LOAD-ASS IGNMENTTYPE = COOLI NGLOAD-RANGE = 20PLANT-EQUIPMENT = OPEN-CENTNUMBER = 1PLANT-EQUIPMENT = DBUNNUMBER = 1 ••SUMr~ER-CHLRNext, schedule the LOAD-ASSIGNMENT instructions.WINTER-DAS = DAY-ASSIGN-SCH (1,24) (WINTER-CHLR)WINTER-WS = WEEK-SCHEDULE (ALL) WINTER-DAS ..SUMMER-DAS = DAY-ASSIGN-SCH (1,24) (SUMMER-CHLR)SUMMER-WS = WEEK-SCHEDULE (ALL) SUMMER-DAS ..CHILLER-SCH = SCHEDULETHRU APR 30 WINTER-WSTHRU SEP 30 SUMMER-WSTHRU DEC 31 WINTER-WSFinally, specify a LOAD-MANAGEMENT instruction to schedule theoperation of plant equipment.LOAD-MANAGEMENTPRED-LOAD-RANGE = 999ASSIGN-SCHEDULE = (DEFAULT,CHILLER-SCH,DEFAULT)Note that in scheduling equipment operation, DAY-ASSIGN-SCH is usedinstead of the usual DAY-SCHEDULE instruction. A DAY-SCHEDULEcommand only accepts numbers as values (i.e., 0., 0.5, 1.0), whilea DAY-ASSIGN-SCH instruction accepts only U-names of appropriateLOAD-ASSIGNMENT instructions. This enables the hourly schedulingof the assignment of PLANT equipment.Example 3:In the following example, the LOAD-MANAGEMENT instruction is usedto select the cooling equipment to be operated based upon theanticipated electric load. The program calculates the anticipatedload as follows:Predicted Load = (QH x A) + (QC x B) + (QE x C),V.61 (Revised 5/81)
