从开放系统能量交换的角度，依据网络图论中的连续性原理，运用一体化建模／仿真技术对管道运输泄漏监测、精确定位进行了研究． 提出了一种新的泄漏检测、精确定位方法——压力点分析（ＰＰＡ）法和采集数据与实时仿真相关分析法相结合的方法． From the perspective of energy exchange in the open system, based on the principle of continuity in the network graph theory, the integrated pipeline modeling and simulation technology is used to study the pipeline transportation leakage monitoring and precise positioning. A new method of leak detection and exact location - Pressure Point Analysis (PPA) and a combination of data acquisition and real-time simulation correlation analysis is proposed.
