Abstract

New technologies are currently delivering protective devices that can enhance the design of protection coordination in modern distribution systems. This paper proposes an integer linear programming (IP) model to find the optimal location of a Fault Transmitter (FT) in the distribution system. The proposed IP model provides the optimal FT allocation considering the minimization of sustained interruption frequency and momentary interruption duration. A study of the appropriate number of FT reveals the best alternative in the proposed adaptive protection scheme. A Monte Carlo simulation with a richer representation of stochastic fault scenarios is used for further evaluation of the solutions obtained with the proposed IP model. The combined strategies allow full-scale studies of the optimal allocation of FT in distribution systems. The results of studies using two test systems certify the benefits of the proposed strategy in fuse-saving coordination and in reducing the total duration of the momentary interruption, which can cause power quality problems.
