Integrating theLoadManagement Function intotheEnergy Control

under$5,000. Tosatisfy expanded loadmanagement needs, theCom¬ panyisnow installing a second-generation controller. This paperdescribes thefirst generation loadmanagement con¬ troller installed in1980as wellas thenew one now being installed. First Generation Controller TheCompany operates a modernEnergy Control Center whichhousesthemainEnergy Control Computer System. Theinitial loadmanagement microprocessor was interfaced totheEnergy Control System through asupervisory Remote Terminal Unit(RTU) located within thefacility. Thisinterface, whilerudimentary formoderncomputer techniques, enabled theCompany toimplement theloadmanagement function in a shortperiod oftimewithout costly computer datalinks. In addition, theinterface supported thecontrol center's manmachinefunctional philosophy ofmaintaining a minimal numberofcomputer peripherals inthecontrol room area.
