Abstract
Wide-area backup protection is a novel technique presented in recent years, which uses multisource information to make fault identification decision and availably prevents catastrophic blackouts. However, the property of algorithm will be deteriorated when information error exists. For the sake of improving the property of wide-area backup protection, this paper proposes an information fusion strategy using genetic algorithm to optimize the decision-making function. The operation information from local directional pilot relay and impedance relay is applied to establish the fitness function. Simulation tests based on IEEE 3-generator and 9-bus system validates the presented algorithm under as many as 3 bits information error.
