Abstract Damage to nuclear power plants causes human casualties and environmental disasters. There are electrical facilities that control safety-related devices in nuclear power plants, and seismic performance is required for them. The 2016 Gyeongju earthquake had many high-frequency components. Therefore, there is a high possibility that an earthquake involving many high frequency components will occur in South Korea. As such, it is necessary to examine the safety of nuclear power plants against an earthquake with many high-frequency components. In this study, the shaking table test of electrical facilities was conducted against the design earthquake for nuclear power plants with a large low-frequency components and an earthquake with a large high-frequency components. The response characteristics of the earthquake with a large high-frequency components were identified by deriving the amplification factors of the response through the shaking table test. In addition, safety of electrical facility against the two aforementioned types of earthquakes with different seismic characteristics was confirmed through limit-state seismic tests. The electrical facility that was performed to the shaking table test in this study was a motor control center (MCC).

通过振动台试验根据频率内容评估MCC地震响应

摘要 核电站损坏会导致人员伤亡和环境灾害。核电站有控制安全相关设备的电气设施，对它们的抗震性能有要求。2016 年庆州地震有很多高频成分。因此，韩国发生涉及许多高频分量的地震的可能性很大。因此，有必要检查核电站对具有许多高频分量的地震的安全性。本研究针对低频分量大的核电站设计地震和高频分量大的地震对电力设施进行振动台试验。通过振动台试验推导出响应的放大因子，识别高频分量大地震的响应特征。此外，通过极限状态地震试验，确认了电力设施对上述两种具有不同地震特性的地震的安全性。本研究中对振动台测试进行的电气设施是电机控制中心 (MCC)。
