Abstract
This paper proposed a fast protection and control scheme of feeder automation (FA) for the modern distribution grid. The smart terminal unit (STU) is installed at each switchgear of the feeder, and STU has a directional over-current component. The adjacent STUs are connected each other by the optic fibre network, and ultimately they are all connected to the central station of FA. STU detects the local current and the status of breaker in real time, meanwhile exchanges the information with adjacent STUs. Through analyzing the information, STU can make a correct identification for a faulted section. Therefore, the faulted section can be isolated and power supply of non-faulted section can also be restored rapidly. Case analysis illustrates that the proposed fast protection and control scheme is valid and feasible.
