基于故障特征隶属函数的电网主设备风险评估方案研究与应用OA北大核心CSCDCSTPCD
Research and Application of Risk Assessment for Power Equipment Based on Fault Feature Membership Function
目前对电网主设备风险评估方法的研究处在发展阶段,且存在不同类型评估对象的评估特征没有通用性、传统评估方法存在人为因素影响和不区分各指标重要程度等问题,笔者在南方电网公司变压器、断路器等电网主设备状态评估导则建立的故障树的基础上,结合设备现场运行数据和故障分布,提出基于隶属函数、相对劣化度、加权平均的故障概率评定方法并引入模糊层次分析法确定各底事件、中间事件的相对权重,实现对设备各部件的风险评估.最后通过某500 kV变电站3号主变的风险评估指标进…查看全部>>
As researches on risk assessment of power equipment is developing,it remains several issues,such as the assessment features of different types of evaluation objects are not universal,traditional assessment methods are vulnerable to human factors and can't distinguish between the importance of each indicator.Based on the fault tree of the condition assessment guidelines of transformers,circuit breakers and other main equipment,combined with field operational …查看全部>>
