A feeder automation scheme based on wireless sensor network

In the traditional feeder automation of distribution network, it´s hard to coordinate switches with each other, the rapidity and selectivity of protection is irreconcilable. To solve this problem, this paper introduces wireless sensor network, which can collect date and communicate it. Together with the recloser and sectionalizer, which are widely used in distribution network currently, a new feeder automation scheme is presented. By putting up network model and fault analysis, a protection criterion, which reference to the adjacent Switch State, is given. Finally, to verify the feasibility of this scheme, the NS2 wireless simulation is given, which analyzes the delay of data transmission and packet loss rate.
