广东大亚湾核电站1号机组于1993年7月28晚9时零5分实现反应堆堆芯首次临界以后,又相继完成了零功率、2％功率和5％功率等不同阶段的各项试验,并于8月31日21时26分,用核蒸汽冲转汽轮发电机达到3000r/min的额定转速,首次以核能发电状态与广东省电网和香港中华电力公司电网并网成功,并网功率为45MW,约占该机组额定功率的5％。 Unit 1 of Guangdong Daya Bay Nuclear Power Station completed various tests at different stages such as zero power, 2% power and 5% power after achieving the first criticality of reactor core at 9:05 on July 28, 1993. At 21:26 on August 31, the steam turbine generator was driven to a rated speed of 3000 r / min by nuclear steam. For the first time, it was successfully connected with the Guangdong Power Grid and the CLP Power Hong Kong Power Grid in the form of nuclear power generation with a grid connection power of 45 MW , Accounting for about 5% of the unit rated power.
