摘要
笔者介绍了大容量发电机断路器(generator circuit breaker,GCB)的结构特点和安装方式,深入分析和总结了大容量GCB在电厂运行中的优势,认为GCB可以提高电厂整体运行的可靠性和效率。采用全生命周期成本评估(Life Cycle Costing,LCC)理论,建立了大容量GCB运行成本估算模型,为电厂从经济性方面决策是否安装GCB提供了依据。最后结合一个实例,对所采用的方法和模型进行了验证。
This paper introduces structures of high-capacity generator circuit breakers （GCB）, and analyzes GCB advantages in power plants. It is concluded that the GCB can improve the reliability and efficiency of power plant operation. Based on the theory of life cycle eosting（LCC）, this paper presents a cost model of high-capaclty GCB, which can provide determinations whether the power plant purchase GCBs from the economic perspective. Finally, through studying a case, the proposed model and method are demonstrated and verified.
