In order to solve the problems that some operating conditions could not be automatically identified and the accuracy of abnormal operating condition recognition was low in the process of monitoring the production and operation of multi-product pipeline system,the intelligent operating condition recognition method was applied to construct a multi-product pipeline operating condition recognition model with real-time monitoring capability. First,logic rule discrimination methods and event logs in the multi-product pipeline system were used to supplement the data labels. Second,the data were segmented according to the start and end time of the operating conditions,and the subsequence of different operating conditions were extracted by using the sliding window. Third,the features of subsequence were extracted to construct the model for operating condition recognition of multi-product pipelines,and the recognition effects of six classification models,namely,random forest (RF),adaptive boosting (AdaBoost),support vector machine (SVM),time series forest (TSF),random interval spectral forest (RISF) and sequence learner (SEQL),were compared and analyzed. Finally,a real multi-product pipeline was used as an example for model validation. The results show that the TSF model has the highest recognition accuracy for the four operating conditions of valve switching,valve internal leakage,pigging and sling pump,and is more suitable for the recognition of short-term operating conditions. In contrast,the recognition precision of the AdaBoost model has a higher probability of including the true value in the 95% confidence interval.

为改善成品油管道系统生产运行监测过程中不能自动识别部分运行状态,以及异常工况识别准确率较低的问题,应用智能工况识别方法,构建具有实时监测能力的成品油管道运行工况识别模型。首先,采用逻辑规则判别方法,并根据成品油管道系统中的事件日志补充数据标签;其次,按照工况的起止时间对数据进行分段,并采用滑动窗口的方式提取不同工况的子序列及其特征;然后构建成品油管道运行工况识别模型,并与随机森林(RF)、自适应提升(AdaBoost)、支持向量机(SVM)、时间序列森林(TSF)、随机区间谱系森林(RISF)和序列学习器(SEQL)等6种机器学习分类模型进行对比,分析其识别效果;最后,以某真实成品油管道为例,进行模型验证。结果表明:TSF模型对阀门开关、阀门内漏、清管和甩泵4种工况的识别精确度最高,且更适合短期内运行工况的识别;而AdaBoost模型的识别精确度在95%的置信区间内所含真实值的概率更高。

| AdaBoost[13] | 具有很高的精度;充分考虑每个分类器的权重;不用对特征进行筛选[13] | 弱分类器数目不好设定;数据不平衡将导致分类精度下降;训练耗时较长[13] |
| SVM[13] | 可避免维数灾难;泛化能力强;算法简单,具有较好鲁棒性;对小样本、非线性及高维模式识别具备独特优势[13] | 难以训练大规模数据集;对参数和核函数选择敏感;实际中需要组合多个二分类实现多分类[13] |
| TSF[14] | 有可解释性,计算效率高,可提取重要时间特征;可克服间隔特征空间巨大的问题[14] | 适用于单变量时间序列,对于多维时间序列数据的分类问题,需要先将多维数据降维,再进行训练[14] |
| RISF[14] | 算法简单;可准确处理噪声较大的数据[14] | 用于长序列分析时,此方法运行较为缓慢[14] |
