Abstract: The squirrel cage induction generator (SCIG) is the fixed speed turbine generator. Though, it is used because of its some advantages, it suffer greatly to meet the requirement of new wind farm grid code, due to dependency on reactive power. In this paper, the permanent magnet synchronous generator (PMSG) wind farm is incorporate with squirrel cage induction generator (SCIG) wind farm, for achieving the optimal performance and some benefits. The permanent magnet synchronous generator (PMSG) can support the reactive power of SCIG wind turbine as well as recover the voltage at the PCC point during the grid fault. The DC link boost chopper is connected with grid side inverter and it boost up the voltage during the grid fault. As well as it improves it can improve the low voltage ride through (LVRT) capability of squirrel cage induction generator (SCIG) based wind farms.
