Fault Analysis of Wind Turbine Generator System Considering Six-Mass Drive Train Model

This paper analyzes different types of symmetrical and unsymmetrical fault of grid connected wind turbine generator system (WTGS), where the six-mass drive train model is considered. The unsuccessful re-closing due to permanent fault is also considered. Moreover, the blade-shaft stresses of the six-mass drive train model of WTGS are also analysed for both successful and unsuccessful re-closing
