核电机组停运对南方电网运行影响研究

介绍了日本＂3.11＂大地震对东京电力公司供电的影响,分析了若南方电网区域内核电机组停运,南方电网运行的情况将会如何。结果显示：2011年若大亚湾、岭澳核电机组停运,当南方电网以小方式运行时可能造成广东电网低周减载动作;当南方电网以大方式运行时可能引起广西部分地区低压减载装置动作,且事故后深圳地区负荷可能受限。2015年阳江核电、台山核电和防城港核电机组分别停运,不会造成其近区电网供电受限,也不会引起系统低周减载或低压减载动作。2016年若海南昌江核电机组停运,当海南电网与广东电网通过2回或1回500 kV交流联络线保持联网时,海南电网低周减载不会动作。

Study on the Impact of Nuclear Power Plant Outage on the CSG Operation

Introducing the impacts of Japan "3.11" earthquake on the power supply of Tokyo Electric Power Company, this paper analyzes the possible operation situations of China Southern Power Grid (CSG as the nuclear power plants in the CSG area being in outage. The results are as follows: If the nuclear power units in Dayawan and Lingao being in outage in 2011, it will happen that Guangdong Power Grid will be in low frequency load shedding as CSG being in valley load period, and some parts of Guangxi Power Grid will be in low voltage load shedding with power cut in Shenzhen district as CSG being in peak load period. If the nuclear power units in Yangjiang, Taishan and Fangchenggang being in outage in 2015, this will not lead the nearby networks being in opwer cut and low frequency load shedding and low voltage load shedding of CSG. If the nuclear power units in Changjiang being in outage in 2016, this will not lead Hainan Power Grid being in low frequency load shedding as the grid being in interconnection with Guangdong Power Grid by one/two 500 kV tie lines.
