Fault contribution considerations for wind plant system design and power system protection issues

The paper discusses design considerations of wind powered generating plants that require knowledge of the fault current contribution of the generators. To provide context, the paper includes brief summary of typical design of the electrical collection and interconnect systems of wind power plants. The impact of fault current contribution on equipment selection is discussed. Common protective relaying practices are discussed and the impacts of fault contributions on setting and selectivity of protective relaying systems are discussed.
