英文摘要 |
Recent earthquake experiences suggest that one of the most critical failure modes of power systems is the damage in substation electrical equipment. The significance of the IEEE-693-1997 Standard, which has become the basis of experimental study of substation equipment in the U.S., is highlighted in this report. An overview of some of the recent achievements in the seismic performance studies related to substation equipment issues is also provided, which include the behavior of bushings, transformers, disconnect switches, and the characteristics of overturning as well as dynamic interaction between inter-connected equipment. |
