摘要
核电厂中的数字化仪控系统（DCS）特别强调其可靠性，因此对供电电源系统有特殊的要求。本文分析了核电厂引入数字化仪控系统后，为保证供电可靠性，在考虑核安全和单一故障准则下，DCS供电电源系统在设计上融入大量的改进。重点分析了全厂断电（SBO）超设计基准事故下，对重要DCS系统的供电解决方案。
The reliability of nuclear power plant Distributed Control System （DCS） is especially emphasized, so DCS has special requirements on power supply system. DCS power supply system has already a large number of improvements in the design. This paper analyzes these improments after the introduction of nuclear power plant distributed control system, in order to ensure the reliability of power supply under the considering of nuclear safety and single failure criterion. In addition, the critical power supply scheme of DCS has analyzed for the accident of blackout （SBO） beyond design basis.
