摘　　要：冗余供电方式可以提高核电站厂用电系统的安全可靠性,基于可靠性理论,分析并推导单向切换双冗余、双向切换双冗余、单向切换多级冗余三类供电模式的可靠性,分析系统结构因素,提出单向切换多级冗余作为核电站实际供电模型;该模型符合纵深防御原则、单一故障准则的设计理念,同时体现供电优先级别、可维修检验的工程要求。Redundant power supply can improve the safety and reliability of nuclear power plant auxiliary power system. Based on the theory of reliability, three kinds of model are designed and deduced. Those are one-way and two-way switching double redundancy, one-way switching multilevel redundancy. The system structures are analyzed. One-way switching multilevel redundancy is selected as the actual auxiliary power supply. This model conforms to some design concept. Such as the principle of defense in depth, single failure criteria. The power supply priority level and maintenance of engineering requirements are considered.
