摘要
在分析西北电网的负荷特性及峰谷差情况的基础上,基于电力平衡计算了西北电网2020年、2025年、2030年3个水平年的核电接纳能力,分析了西北大规模风电开发对核电接纳能力的影响。结果表明:西北电网接纳核电能力与风电开发规模和进度紧密相关。在不考虑风电的情况下,西北电网2020—2030年可接纳核电能力为26 000～48 500 MW。若考虑全额收购规划风电情况下,西北电网2020年前已无核电调峰空间,2030年也仅有最大约12 000 MW的核电空间。
Based on an analysis of the load characteristics of the northwest power grid, especialy its peak and valley values, this paper calculates the grid＇s acceptance capacity of nuclear power in 2020, 2025 and 2030, respectively, based on electric power balancing. It also analyzes the impacts of the large-scaled wind power development on the acceptance capacity of nuclear power. The results show that the ability to accept nuclear power to the grid is closely related to the scale and progress of wind power development in the region. Without wind power, the grid can accept 26 000 - 48 500 MW of nuclear power from 2020 to 2030. However, with all the wind power generated in the region entirely integrated in the grid, the grid has no load peaking capacity for nuclear power in 2020; whereas it has only 12 000 blW load peaking capacity for nuclear power in 2030.
