Adaptive protection and control strategy for interfacing wind-power electricity generators to distribution grids

Recently electricity generation from wind power has been increasingly popular worldwide. This paper proposes an adaptive protection and control strategy for interfacing the wind-powered distributed generators into the utility power distribution grids. The requirements for the interfacing are defined according to the IEEE-1547 standards. This paper presents the adaptive interfacing controls and protections for three common types of wind-powered generators: doubly-fed induction generators, permanent-magnet synchronous generators, and squirrel-cage induction generators. The design for the adaptive protection and control presented in this paper uses state-of-the-art digital signal processing technology and modern computer networking technology. This paper presents a new two-layer computer network architecture for real-time monitoring the operations as well as the impacts of wind-powered electricity generations in the utility distribution systems. This architecture is fault tolerant and is designed for monitoring power distribution systems with multiple (over hundred) feeder nodes.
