The Induction Generator (IG) wind turbine system uses Fixed Speed Wind Turbine (FSWT) system. Due to high dependence on reactive power, it bears achieving new wind grid code requirements. IG requires high reactive power during network disturbances. Nowadays, Flexible AC Transmission System (FACTS) devices are available in the market for compensation of reactive power of IG during network faults. The use of FACTS devices in wind system increases the total budget. So, we have to concentrate on new innovative kind of topology which is cost-effective and gives the exact solution to the problem. The new idea is to locate the Permanent Magnet Synchronous Generator (PMSG) near to IG and connect via underground cable at Power Cable Connects (PCC). It has the ability to fulfill the requirements of reactive power during network disturbances. When there is a fault on network reactive power, requirement of IG is fulfilled using a combination of it with PMSG to meet wind grid code requirement. Low Voltage Ride Through (LVRT) or fault ride through characteristic of FSWT IG is analyzed using Indian grid code. The simulation results clearly showed that the proposed topology might be a good solution to augment the LVRT requirement of fixed speed Wind Turbine Generating System (WTGS) and for achieving certain optimal operating performance and economic benefits. The proposed topology illustrates the defined reactive power and voltage retort, which maintains the FSWT IG system-based wind farm to ride through the grid fault without installation of any additional devices.


With the rapid industrial development in the world, energy shortage has become one of the biggest issues many countries are facing. The crude oil market goes up day-by-day, thus necessitating the modernization of domestic and industrial customer installed small wind turbine for reduction of energy bills and supporting environment using green energy. One can also make money by selling the surplus power to national grid.
