Present generating stations are not competent to satisfy the present load demand. Hence, the availability of conventional fuels is limited, one should re-think for the new source of energy which will interminable in nature, harmless to our ecology and secure future demand. Due to modernization and industrialization, the electric power consumption increases drastically, but the energy source is not competent enough to satisfy the consumer energy demand and hence renewable energy like wind energy, fuel cell, solar energy, batteries or ultra-capacitor get attention in distributed power generation system. The Faults in the system with a continuously varying in nature affects the normal operation of the system. The cause and severity of such faults play a vital role while designing a protection scheme in the standalone system. In this paper, Electric model of an 11.58KWSolar PV-Based standalone system is developed in Matlab/Simulink and various shunt faults analysis are performed and analyze the response of the system before fault, during fault period and after fault conditions. Adetailed short circuit (SC) analysis puts light on various short circuit conditions and provides useful analysis.
