高压电气设备抗震可靠性分析方法
|
摘要
提出了基于反应谱理论的高压电气设备抗震可靠性分析模型与计算方法。利用极大值分布理论反映地震动的随机过程特性，结合一次二阶矩阵理论建立了可以同时反映地震动变异特性与高压电气设备材料变异特性的高压电气设备抗震可靠性分析方法。应用这一方法，可以系统地进行高压电气设备的抗震可靠性分析，计算出高压电气设备在不同烈度、不同场地条件下的抗震可靠性指标与可靠概率。所得结果可为高压电气设备抗震性能评价与电力系统抗震可靠性分析提供依据。
An analysis model of calculating seisinic reliability of high voltage electrical equipments is established in the paper. Considering variability of ground motion and of structural material simultaneously, the model presents a new way to calculate seismic reliability of high voltage electrical equipment. As an example, seismic reliability index and probability of a type of high voltage electrical equipment are given out considering different seismic intensity and different site types. It is shown that the suggested algorithm lays a foundation for seismic reliability assessment of power stations and of district power system.n
