基于云模型的智能变电站二次设备状态评估

Abstract

变电站二次设备状态评估是实现状态检修的基础，是保证一次设备安全运行的关键工作，而二次设备故障机理复杂，存在隐性故障，其状态评估所需指标更为复杂。提出基于云模型的智能变电站二次设备状态评估方法，建立基于云模型状态评估方法流程，划分评估智能变电站二次设备状态等级，采用层析分析法变权重方法进行处理。结果表明采用云模型的评价方法能更准确的评估智能变电站二次设备运行状态。为智能变电站二次设备状态检修工作提供理论依据。 Substation secondary equipment condition assessment is the basis to realize condition mainten-ance, and the key ensuring the safe operation of the equipment. However, the mechanism of sec-ondary equipment fault is complex, which may have recessive fault, and the index required is more complex. This paper proposes a new method for smart substation secondary equipment condition assessment based on Cloud Model, establishes evaluation flow process, divides the condition level, and uses the analytic hierarchy process and varied weight process. The results show that this method can evaluate the smart substation secondary equipment condition more accurately, and provide theoretical basis for the maintenance of it.
