| 摘 要： | 以近年来西南地区发生的震级超过5级的大地震为例,分析了大型水电机组在地震过程中的运行状态监测数据,并结合现代水电站机电设备抗震设计和机组有限元计算,阐明地震对水轮发电机组安全运行的影响限度。结果表明,电站在承受坝址基本地震烈度及以下地震时,水轮发电机组安全运行不会受到较大影响,但应考虑有效的应对措施,以减轻强震带来的次生灾害。

Impact of Earthquake on Safe Operation of Hydroelectric Set |
| |
| Abstract: | Taking the earthquake magnitude in excess of the M5.0 in southwest of China in recent years as examples, this paper analyzes the running status monitoring data of large hydroelectric set in earthquake. Meanwhile, combined with the seismic design and finite element analysis of electromechanical equipment in modern hydropower station, the influence of earthquake on the safe operation of hydroelectric set is clarified. We draw a conclusion that there is not obvious impact on the safe operation of hydroelectric set when suffering earthquake below the basic seismic intensity, But some effective measures should be taken up for easing secondary disasters of the earthquake. |
