Evaluation the effects of the synchronous generator circuit breaker on the reliability of busbar layout in power plant substation in deregulated electricity market

Abstract

One important issue in power plants is the reliability. In the power systems, the power plant outage is a critical situation and as a matter of fact, the layout and the configuration has direct effect on the outage. In this paper, the effects of synchronous generator circuit breakers (SGCB) on the one & half and two circuit breaker layouts are investigated. In the simulation of this paper, the minimal cut set and path are employed. The results of the simulation and economic evaluations demonstrate the SGCB increases the reliability indices as well as reducing the cost in the deregulated electricity markets.
