What is SCADA/EMS and SCADA/DMS?
SCADA/EMS (Supervisory Control and Data Acquisition/Energy Management System) supervises, controls, optimizes and manages generation and transmission systems. SCADA/DMS (Distribution Management System) performs the same functions for power distribution networks. Both systems enable utilities to collect, store and analyze data from hundreds of thousands of data points in national or regional networks, perform network modeling, simulate power operation, pinpoint faults, preempt outages, and participate in energy trading markets. Computerized control Although the roots of power control go back to the 1920s when ABB supplied its first remote control system for a power plant, it was not until the 1960s and the advent of computerized process control that modern power network control systems as we know them today became possible. Most SCADA/EMS systems at that time were designed exclusively for a single customer. Power systems were vulnerable, and there was a need to develop applications and
