Abstract
Publisher Summary This chapter discusses various aspects of supervisory control and data acquisition (SCADA) systems. SCADA encompasses the collection of information, transferring the data over physical mediums, and the processing and display of the data at the master station. The SCADA master station displays sequence-of-event reports and disturbance recordings when required, provides an active operator interface for supervisory control, and remote configuration of intelligent electronic device and other devices. A SCADA master station may be utilized to control only one substation, as will be the case in large generation or transmission high-voltage substations. The hardware for a power system automation master station normally consists of one or more desktop personal computer or workstations, with its normal peripheral devices and one or more communication ports. Three software platforms are applicable to the SCADA master station for a power system automation system that includes the operating system software, the SCADA system software, and the SCADA application software. It is suggested that different levels of integration be applied between the SCADA operating software and application software, depending on the specific software and the tasks it is required to perform.
