Use of renewable energy sources is encouraged to ensure the continuous supply of electricity to the customers. The system may sometimes face problems due to internal and external factors, which leads to the faults in the system. This paper presents simulation and experimental study on the effect of phase faults in grid connected solar photovoltaic plant. The effect of faults because of internal and external factors has been analyzed with the simulations of synchronized 200kW grid tied solar photovoltaic system using MATLAB and experimental analysis of faults in 500W of prototype grid connected system. Therefore it is necessary to examine the fault ride through capability of the system, so that the power production capacity of a solar photovoltaic system can be enhanced. The variations in solar irradiance level and temperature influences the power output from the plant and an incremental inductance maximum power point tracking technique is applied to get the peak power output. Thus, the changes in electrical parameters and solar system behavior in faulty conditions has been examined.
