Effect of the Bus-Section and Generator-Breaker on Reliability Indices of Busbar Schemes in Power Plant

摘要

One of the main subjects in power systems is increasing the power-plant reliability in emergency conditions. In power systems, the power-plant outage is considered as a critical position, which leads to economic damages and instability problems. Surely, the type of the busbar layouts in power stations affects the power-plant availability. In this study, the effect of the bus-section and generator-breaker in one and half-circuit breaker system and two-circuit breaker system and the effect of the above points over reliability parameters were investigated. For simulation, the cutest and path algorithm have been applied. Finally economical evaluations of the simulation results show the effectiveness of the bus-section and generator-breaker in busbar layout of power-plant substations.
