Összefoglalás

Nowadays the Smart Grid phenomenon pervades the power industry. This is a summary notion that includes all the up-to-date Info Communication Technology developments that raises the reliability and promotes the greener energy production. In the education all the new aspects must be introduced that is why a demonstrational wall panel is planned to show the operation of the island operation, Load-Generation balance control, Audio- and radio frequency ripple control, Smart meter, Power Quality monitoring, etc. This tool fits in the concept of laboratory that shows all the non traditional power devices and prepared by the students at Obuda University.
