Short-circuit Current Characteristics of Wind Generators

To study the effects of wind generators on distribution system protection，the short-circuit current（SCC） characteristics of wind generators is important.Although there are many researches on the issue，a clear agreementhas not been reached so far.The SCC characteristics for different wind generators are studied.PSCAD simulation isperformed in the same system integrated with different kinds of wind generators，and their results are comparedwith those reported in IEEE papers.The detection possibility by overcurrent relay（OCR）is discussed based on thesimulation results
