Abstract :
This paper focuses on the method of fault position for stochastic prediction of balanced and unbalanced voltage sags in a distribution system. The theoretical background about the short circuit analysis is presented and residual phase voltage equations for balanced and unbalanced fault are derived. Thereafter area of vulnerability based on the assessment of voltage sags have been presented for an Indian distribution system.
