A new algorithm for reliability evaluation of radial distribution networks

Abstract

This paper proposes a new algorithm for reliability evaluation of complex radial distribution networks. The proposed algorithm is based on failure mode and effect analysis (FMEA) method. The paper talks about the definition of network topology using a matrix which is modified and new matrices are derived. These matrices are used for evaluation of load point reliability indices. The rows and columns of these matrices correspond to branches and buses of the network respectively. Each element of these matrices attest a specific relation between a faulted branch and the network bus. The above mentioned salient features make the whole algorithm straight forward to implement in a real distribution system. Thus, the results obtained from this method are verified with the Bus 2 of RBTS.
