中文摘要:
      提出变电站地震可恢复性等级划分方法,设立评价变电站地震可恢复性的量化指标——可恢复性指数,给出基于建筑物和高压电气设备的权重系数与震害指数的变电站可恢复性指数计算公式,确定可恢复性指数与可恢复性等级对应关系,通过变电站实际震害与恢复样本研究建立变电站可恢复性矩阵。研究结果表明:随着可恢复性指数降低,变电站可恢复性越来越差,当可恢复性指数低于0.45时,变电站达到极难恢复的阈值;变电站所处的地震烈度越高时,变电站可恢复性就越低,恢复时间也越长。在9度区,变电站可恢复性指数开始快速降低,多数变电站为可恢复和难恢复,烈度为10度及以上地区,变电站极难恢复。
英文摘要:
      In this study, a grading method of the seismic resilience of substations is presented. The quantitative indicator "resilience index" is proposed to evaluate the seismic resilience of substations. A formula for computing the resilience index based on seismic intensity and the weighting coefficients of buildings and high-voltage electrical equipment is also proposed. The corresponding relationship between the resilience index and resilience grades is determined. The substation resilience matrix is also established through the study of actual seismic damage and recovery samples. The result shows that the seismic resilience of substation becomes weaker as the resilience index decreases. Once the index drops to less than 0.45, the substation would reach a threshold beyond recoverability. Generally, the higher the seismic intensity is, the weaker the substation resilience will be, and a longer restoration time will be needed. Most of the substations are conditionally restorable and hard to be restored in the area of 9-degree seismic intensity, and will be almost unrestorable in the area of 10-degree seismic intensity.
