Abstract:

© 2004-2012 IEEE. Power packet dispatching system (PPDS) which integrates information into power distribution has been proposed recently. A PPDS distributes power in a packet form to the loads. It offers reduced power processing stages and smart power handling according to load demand and power generation capacity. The PPDS comprises of a mixer which generates PPs of different voltage levels and a router which distributes power to the designated loads. In existing PPDS, while the mixer generates the voltage packets and the router distributes them, the current of each packet is simply determined by the impedances of the power cable and the loads. Hence, there is no measure to monitor and protect the system during an over-current scenario. In this brief, an over-current protection scheme based on a simple analog circuit and integrated with the PPDS is proposed. In this brief, DC system is considered due to its reliability, efficiency and easy integration of renewable energy sources compared to AC system. It is able to prevent false tripping and provide accurate information for the router to isolate the load when the over-current is genuinely detected. The proposed method has been experimentally verified through a laboratory prototype.
