变压器震后剩余寿命评估模型的研究

Gaoya dianqi, 2013
电力是国民经济的动力,而5.12汶川发生8.0级大地震后,变压器相当于经历了一次超出相应承受能力的破坏性试验,损失严重。为科学了解和分析变压器受灾情况,以确保现有投运变压器的安全可靠运行,有必要对震后变压器的受损程度及剩余寿命进行调研和评估,从而为变压器的全寿命周期管理和安全运行提供依据。该研究把统计学、数值分析、神经网络、管理科学及建筑学等多类学科融入到变压器震后剩余寿命评估中,建立了基于可靠性的变压器震后剩余寿命评估柔性模型。通过对汶川地震后四川省十三个地区变压器震前和震后的数据抽样收集、整理 ...

基于电流监测和动态电阻分析的电容器组SF₆断路器电寿命评估系统

Gaoya dianqi
电容器组SF6断路器电寿命状态监测工作对保障电网安全可靠运行意义重大。文中融合触头磨损计算方法和动态电阻分析法对SF6断路器电寿命进行评估，提出SF6断路器电寿命评估判据，首先基于断路器电流监测数据计算断路器触头磨损，对断路器电寿命状态进行判断预测，再利用动态电阻分析法印证判断出SF6断路器的真实状态，兼顾触头磨损计算法的实时性和动态电阻法的准确性。基于所提判据，研发了一套融合触头磨损和动态电阻的SF6断路器电寿命评估系统。该系统可基于断路器投切数据和动态电阻准确地评估SF6断路器的电寿命 ...
