Abstract

In this project a solid state transformer is used for integrating energy generated from solar and wind source and the resultant energy is supplied to load, instead of ordinary step up transformer solid state transformer is used. The proposed configuration meets latest grid code demand of wind turbine during fault condition. Based on the grid code demand, the Grid Interfacing Converter (GIC) has supplies reactive current during the fault condition. The fault is observed by perceiving positive sequence voltage magnitude and it is active in both types of fault conditions like symmetrical and unsymmetrical. The fault will exist for few milliseconds (ms) and the reactive current is added by GIC.

The turbine does not allow any variation in operating condition. The Solid State Transformer (SST) provides improved operation and performance when compared with a conventional transformer. Renewable source of energy is demand of the hour and hence the hybrid systemof solar and wind source helps in efficient use of renewable energy. When the wind energy generation is not reaches the rated value, this hybrid system has the ability to provide reactive power to the grid.
