Active Learning Method for Abnormal Operating Conditions of Natural Gas Gathering System

Various abnormal operating conditions in natural gas gathering system pose a threat to safe production. This paper proposes an intelligent processing system model for abnormal operating conditions. The abnormal operating conditions classification prediction module of the model adopts the active learning method, which can classify the abnormal type in real time and accurately, and provide a basis for the system to recommend appropriate processing schemes to experts. Firstly, use the SCADA system to monitor data in real time and perform abnormal conditions warning. Secondly, we use the active learning algorithm to classify the early warning of abnormal operating conditions. The classification results provide support for constructing the abnormal working condition inference engine, and then implement intelligent decision-making assistance. The experimental results show that the proposed method can save the cost of experts, identify the types of abnormal operating conditions, and propose a reasonable solution.
