| Abstract |
This paper reveals two typical phenomena of Squirrel-Cage Induction Generator (SCIG) based wind
turbine during the voltage sag, such as asynchronous induction generator going into stall and the shocks of the
electromagnetic torque with polarity reversal, the result shows low voltage ride-through(LVRT) capability of SCIG
wind turbine is very poor. A method of using a stator series resistance device is proposed for SCIG based wind
turbine LVRT. Both detailed analysis and simulation results demonstrate it is an safety and effective method to
ensure the SCIG based wind turbine against the impact of the PCC voltage sag, and provide maximum active and
reactive power to support the grid stability and security. |
