Gas Pipeline SCADA System Design And Leakage Detection Research

Gas pipeline SCADA system makes use of a variety of instruments, computers ,other electronic control devices and automatic tools, to automate detection of pipelines, surveillance, control and management to ensure the safety of the pipeline, stable economic operation. Pipeline SCADA System can achieve the goal of optimal technology of various economic targets, enhance economic efficiency and labor productivity, energy conservation, improved labor conditions, ensure the environmental health and safety etc.. This thesis studies the status of SCADA systems, and systems development, analyzes the reasons and the harmfulness of a pipeline leak, points the significance of a gas pipeline leak detection. Combining Yantai gas Pipeline project, this paper introduces gas pipeline SCADA system functions, basic technical requirements and system configuration in detail. At the same time, focusing on system software and hardware configuration, this paper introduces the central control level station and system level station. Through comparing of the detection methods currently used for the pipeline leak detection, this paper research on acoustic leakage detection technology for the gas pipeline. Combining the SCADA system features, it provides a set of practical application SCADA system for gas pipeline leak detection. System composition and function of the gas pipeline SCADA system are discussed in this paper.
