摘　　要：变电站系统抗震韧性评估为提升其抗震性能提供指导,有助于减少震后各类损失,为了优化其韧性评估的运算效率,文中提出一种向量化快速评估方法。首先建立设备破坏概率矩阵,结合随机抽样获得设备状态矩阵,利用向量化分析模型模拟变电站工作过程,最后定义了系统评价指标,通过蒙特卡洛抽样量化计算变电站系统的剩余功能和抗震韧性指标。利用该方法对一典型220 kV变电站进行抗震韧性快速评估,高效地量化对比了在不同地震强度下加固各类设备对系统韧性的提升,并基于多维指标找寻多种关键设备及多维加固策略。该方法可为特高压变电站系统韧性评估提供技术支持。The seismic resilience assessment of substation system provides guidance for improving its seismic perfor⁃mance and helping reduce various damage after seismic.In order to optimize the operation efficiency of its resilience assessment,a kind of fast assessment method based on vectorization is proposed in this paper.Firstly,the equipment destruction probability matrix is set up to obtain the equipment state matrix in combination with random sampling..Then,the operating process of substation is simulated by using the vectorization analysis model.Finally,the assess⁃ment index of the system is defined,and the residual function and seismic resilience index of the substation system is quantitatively calculated through the Monte Carlo sampling method.The fast assessment of seismic resilience of one typical 220 kV substation is performed by the method,which efficiently quantifies and compares the improve⁃ment of reinforcing various equipment to the system resilience under various seismic intensities and,on the basis of multiple⁃dimensional indexes,search various key equipment and multiple⁃dimensional reinforcement strategy.This method can provide technical support for the resilience assessment of UHV substation system.
