Abstract
MAZLUMI, K. and ABYANEH, H. Askarian. Overcurrent relay coordination effects on reliability indices. S. Afr. J. Ind. Eng. [online]. 2008, vol.19, n.2, pp.109-123. ISSN 2224-7890.
Protection system failures are the main causes of cascading outages. There is a need to evaluate reliability indices, yet the effects of relay coordination methods have not yet been investigated in the existing literature. In this paper, an algorithm based on sequential Monte Carlo simulation is proposed to find the reliability indices for different overcurrent relay coordination methods. The proposed algorithm is applied to the results of three different relay coordination methods of a sample network. Then the reliability indices for the results of three different relay coordination methods are compared, and it is shown how the reliability indices are affected by the results of relay coordination methods.
