Abstract:
Directional overcurrent relays (DOCRs) are widely used to protect power systems. For optimalcoordination of DOCRs, several techniques have been proposed to solve this problem. A common wayof optimal coordination of DOCRs is using evolutionary algorithms such as genetic algorithm (GA). Inthis paper, a novel strategy for DOCRs coordination is proposed. In the proposed strategy, a newobjective function (OF) is introduced. The proposed objective function can removed mis-coordinationbetween paired relays and can result in better coordination. Proposed OF is applied to 6-bus and 30-bussample networks.
