基于关联规则的船舶供电系统故障检测方法研究

摘要

The current ship power system,the fault information of properties affected by ship components of complex,often incomplete, the equipment fault intelligent detection accuracy is not high.Association rules to incomplete signal weakening and signal processing has a lar-ger advantage,on the basis of fully working principle of the ship power system,based on the fault signal correlation model is set up,the ship power supply system on the protector,the abnormal signal attribute based association rule breaker.Use the simplest fault decision table at-tributes statute formation,comparing the decision fault information associated with the degree of judgment of fault location.The experimen-tal results show that the scale and related equipment fault diagnosis system in ship power protection action incomplete environment,high ac-curacy of fault diagnosis,to meet application requirements.%当前的船舶供电系统中，相关故障信息属性受到船舶元器件复杂度的影响，往往不完整，对该设备的故障智能检测准确性不高；关联规则在不完整信号以及弱信号处理方面有着较大优势，在充分船舶供电系统工作原理的基础上，文章通过建立故障信号关联模型，对船舶供电系统上保护器、继路器的异常信号属性建立关联规则；利用最简属性规约形成故障决策表与故障信息关联决策度进行对比，判断故障位置；实验结果表明，该故障诊断系统在船舶供电规模和相关设备保护动作不完整的环境下，故障诊断的准确率较高，满足应用需求。
