摘　　要：介绍了AP1000核电厂的电气系统及中压厂用电源切换的设计特点,对核电、常规火电的厂用电切换设计进行了差异比较,分析了AP1000核电在非正常运行方式下的中压厂用电源切换特点及设计优化过程。通过设计优化,取消了辅助锅炉运行闭锁厂用电快切,并提出了相关建议,为后续AP1000工程提供参考。Introduction was made to the design characteristic of the electrical system and medium voltage buses transfer of AP1000 nuclear power plant.This paper compared the difference of medium voltage buses transfer between nuclear power plant and normal thermal power plant and analyzed the medium voltage buses transfer characteristic and design optimization procedure of AP1000 nuclear power under abnormal operation mode.Via design optimization,the buses transfer wasn’t be blocked any longer when auxiliary boilers were in operation.This paper gave the relevant suggestion,which provides references for the follow-up AP1000 project.
