Rapid depletion of the conventional energy sources has been a driving factor in the phenomenal advancements of renewable energy systems. Bulk integration of such renewable energy sources has given rise to a new dimension to various classical power system analysis problems impacting the system which need to be analysed before grid integration. Wind turbine systems, which are widely used along with the solar PV systems, are majorly power electronically controlled equipment. They possess the capability of connectivity in the system during faults along with Low Voltage Ride Through(LVRT) characteristics for supporting the voltage profile of the system. These current injections lead to the problem of fault analysis becoming non linear and calculation extensive for various time domain simulations. This paper presents an extension of the concept of classical fault analysis to form “Fault Coefficients” which are used along with Newton Raphson technique, to find current contributions of Voltage Source Converter (VSC) based wind turbines for all types of symmetrical and asymmetrical faults. The approach can be used even for very large networks, as the sparsity of the system is maintained in this approach.
