针对山东电网"西电东送"的格局及半岛环海的地形特征,分析了山东电网的磁暴灾害风险。结合2015年山东电网500 k V主网架,选取典型磁暴感应出的地面电场数值,使用MATLAB仿真软件计算了最大运行方式下变电站的GIC水平。计算结果表明,连接线路数少、位于电网末端或拐角、连接有长线路的变电站容易诱发较大的GIC,其绝对平均值最高可达25.7 A,成为危险点变电站。结合磁暴灾害对省域规模电网的影响,综述了山东电网磁暴灾害的研究进展,并提出了进一步研究"海岸效应"影响机理和构建GIC监测平台的建议。 According to the pattern of "power transmission from west to east" and the terrain characteristics of the peninsula, the risk of magnetic storm disaster in Shandong power grid is analyzed. Combined with the 500 k V main grid of Shandong Power Grid in 2015, the ground electric field values of typical magnetic storms were selected. The GIC level of the substation was calculated by MATLAB simulation software. The results show that the number of connecting lines is small, located at the end of the grid or corner, connecting a long line of substation easily lead to a larger GIC, the absolute average of up to 25.7 A, a dangerous substation. This paper summarizes the research progress of magnetic storms in Shandong province, and puts forward some suggestions to further study the mechanism of "coastal effect" and construct GIC monitoring platform.
