Complete HMI devices are master units that allow to supervise the data acquisition process. Serving as the system’s central processor, the HMI also allows users to regulate and modify the system as needed with add on features allowing to use HMIs to interact with the gathered data through graphical user interfaces, usually computer monitors, and compile reports for later use. Network connectivity (field buses, protocols, etc.) This automation includes DG operation & voltage or VAR control and DG automatic switching. DG voltage control performs voltage regulation and capacitor placement operations to existing APFC are programmed at site while feeder switching deals with remote switching of various feeders, detection of faults, identifying fault location, isolating operation and restoration of service. In this system, the architecture continuously checks the faults and their location by using wireless fault detector units deployed at various outgoing stations. In addition, it facilitates the remote circuit switching and historical data collection of feeder parameters and their status. different DG must be automated with modular and integrated devices in order to decrease the number and duration of outages. Remote-Control Units (RTUs) maintenance and operational duties such as remote load switching, capacitor bank insertion and voltage regulation. The entire network is connected with a communication medium in order to facilitate remote energy management at the central monitoring station.
