BOILERS = LOAD-ASSIGNMENTTYPE = HEATINGLOAD-RANGE = 5PLANT-EQUIPMENT = BOILER-1NUMBER = 1LOAD-RANGE = 10PLANT-EQUIPMENT = BOILER-2NUMBER = 1LOAD-RANGE = 15PLANT-EQUIPMENT = BOILER-1NUMBER = 1PLANT-EQUIPMENT = BOILER-2NUMBER = 1 .•Since OPERATION-MODE is not defined in the above example, theequipment operates sequentially, i.e., RUN-NEEDED, to meet theheat i ng load.Another way of specifying the same operation for these boilers is asf 011 ows:BOILERS = LOAD-ASSIGNMENTTYPE = HEATINGLOAD-RANGE = 5PLANT-EQUIPMENT = BOILER-1NUMBER = 1LOAD-RANGE = 15PLANT-EQUIPMENT = BOILER-2NUMBER = 1PLANT-EQUIPMENT = BOILER-1NUMBER = 1 ..Since defaulting the OPERATION-MODE instructs the program to operatethe equipment sequentially, heating loads between 5 and 10 MBtuh willrequire only BOILER-2 to run. Loads above 10 MBtuh require theadditional operation of BOILER-1. Defining OPERATION-MODE = RUN-ALLwould force the simultaneous operation of both boilers when the loadis greater than 5 MBtuh.Example 2:A diesel generator, DIESEL-1, is defined by a hypotheticalPLANT-EQUIPMENT instruction to be capable of producing 10 MBtuh ofelectricity. If the user wishes to operate this unit whenever theelectric load exceeds 20 MBtuh, the user specifiesELEC = LOAD-ASSIGNMENTTYPE = ELECTRICALLOAD-RANGE = 30PLANT-EQUIPMENT UTILITYNUMBER = 20PLANT-EQUIPMENT = DIESEL-1NUMBER = 1V.55 (Revi sed 5/81)
