“…An efficient sequence of all the other relays will be determined to reduce the number of iterations and to accelerate the convergence of the coordination process. The sequence for setting the relays is displayed by a relative sequence matrix (RSM) [2]. In setting a relay, determining which relays will be backed up by this relay is necessary.…”

“…In setting a relay, determining which relays will be backed up by this relay is necessary. The set of all primary and backup relays sorted by the backup relays is the set of sequential pairs (SSP) [2][3][4].

“…However, with the increase in the number of buses and loops in the system, the problem of finding the suitable BPS is practically complicated [7]. The depth-first search can enhance the efficiency of finding all the loops [2]. In [8], the methodology developed does not require the generation of all the directed loops.…”

-The current study presents a zero-one integer programming approach to determine the minimum break point set for the coordination of directional relays. First, the network is reduced if there are any parallel lines or three-end nodes. Second, all the directed loops are enumerated to reduce the iteration. Finally, the problem is formulated as a set-covering problem, and the break point set is determined using the zero-one integer programming technique. Arbitrary starting relay locations and the arbitrary consideration of relay sequence to set and coordinate relays result in navigating the loops many times and futile attempts to achieve system-wide relay coordination. These algorithms are compared with the existing methods, and the results are presented. The problem is formulated as a setcovering problem solved by the zero-one integer programming approach using LINGO 12, an optimization modeling software.

SUMMARY This paper proposes an effective approach based on particle swarm optimization to identify the break point set. Determining the directional loops and the optimal break point set in the multiloop is the first step during setting and coordination of directional relays in system protection. Arbitrary starting relay locations and arbitrary consideration of relay sequence to set and coordinate relays will result in navigating loops many times and usually result in futile attempts to achieve system‐wide relay coordination. First, the network is reduced if there are any parallel lines or three end nodes. Second, all the directed loops are enumerated to enhance the algorithm. In this paper, the problem is formulated as a set covering problem, and break point set is determined using particle swarm optimization technique. Effectiveness of the proposed algorithm is implemented in different test system, and the results are compared with the existing methods. Copyright © 2011 John Wiley & Sons, Ltd.
