The distribution network has characteristics different from the transmission system. Distribution networks are commonly 1. three-phase unbalanced 2. radial with sometimes weakly meshed topology 3. with high resistance to reactance (r/x) rations here, an equivalent current injection method is used in rectangular coordinates to analyse the given radial distribution system. The FDLF method uses the NR-algorithm, with a constant Jacobian matrix. This matrix is further decoupled into two identical sub-Jacobian matrices.

AITKEN S INTERPOLATION Aitken s procedure yields systematically and successively better interpolation polynomials corresponding to successively higher order truncation of Newton s divided difference formula. Given a set of x and corresponding f(x), estimate f1(x1) f1= aitkenInterp(x,f,x1) f = corresponding function of x f1= corresponding function of x1
