摘要
为快速检测柴油机异常情况,分别采用空间几何法和距离法对记录的35组MAN B&W 6S35ME-B9型船用低速柴油机在25%、50%、75%和90%负载下的热工参数进行异常数据检测,确定异常数据样本。通过两种方式的交叉验证,发现检测结果相近,论证了两种方法的可行性。
In order to detect the abnormal situation of diesel engines quickly,for 35 groups of thermal parameters of MAN B&W 6 S35 ME-B9 marine low-speed diesel engine under load conditions of 25%,50%,75%and 90%,the abnormal data are detected by the space geometry method and the distance method,respectively.The abnormal data samples are determined.Through the cross-verification of two methods,it is found that their detection results are similar,and the feasibility of the two methods is demonstrated.
