Microcontroller Based Control Scheme for Solar PV System under Asymmetrical Fault Condition

Mohini W. Badwaik | Prashant P. Jagtap

Abstract: In the current situation there is a speedy growth in request of electrical energy and will be duple in upcoming days but still the use of Non-conventional energy sources is relatively very low over conventional energy sources. But now the several awareness programs of several societies results in to the growth in utilisation of Non-conventional energy sources like solar, geothermal, winds etc. While getting the electrical energy from Non-conventional energy sources it is very difficult task to maintain the quality of power with less interruptions to avoid the failure of grid, since there are various faults and problems occurs in the network. For example in the case of solar power plant shadowing, short circuit, open circuit etc. This paper focuses on the occurrence of Asymmetrical fault and its control schemes while deriving the Electrical energy from one of the largest and free of cost source of Non-conventional energy i. e. Sunrays through the Solar panel. Asymmetrical fault is nothing but short circuit fault which is analysed and controlled by the voltage support control method and positive sequence recovery with the help of microcontroller based inverter is to be discussed in this paper.
