Supervisory Control and Data Acquisition for Energy Management Systems

Energy management can be achieved through various activities such as using more energy efficient devices and utilizing power quality improvement. However the next stage of improvement is to implement a strategy for system optimization. This can be done through detailed analysis of energy and process data and through equipment and facility monitoring. This paper presents supervisory control and data acquisition system for energy management system. It's concept and all basic platform will be shown. To achieve satisfying level of optimization, there is a need to bring energy consumption and process data together and all this data will be listed here. The process analyst within SCADA system combines power data and process data (both analogue and digital) to enable a real-time analysis of the impact of process changes and energy consumption. In this respect, with SCADA system, some relations could be changed like avoiding peak demand processes which results in higher bills, moving processes to lower cost time periods, adjusting usage during idle process conditions and reducing usage on request from the energy company.
