摘　　要：介绍了高负荷密度工业园区电网的特征及其短路电流超标这一突出问题,以青海省西宁甘河工业园区供电电网为例,分析了目前控制短路电流的各种措施对于此类电网的适应性,得出了以优化电网结构(采取高低压电磁解环)为主,调整电网设备(主变加装中型点小电抗)为辅的解决策略,为今后同类型园区电网规划提供指导。In first this paper gives an introduction to the characteristics of the power grid for the industry garden with high density load and the problem that the short circuit current in the power grid is higher over the standards. And taking the Ganhe industry garden as example,this paper analyzes applicability of the various measures to control the short circuit current in the power grids,and gives a solution primary by optimizing the power grid structure（ using high and low voltage electric-magnetic loop unlinking） and secondary by adjusting equipments（ adding small reactor at the neutral point of the transformer）,providing a guide to the power grid planning in future.
