摘　　要：利用VC++6.0语言,采用有限元节点法,研制出燃气管网水力计算自适应优化仿真软件。该自适应优化仿真算法在深入研究燃气管网水力计算结果与实际测量值之间存在偏差主要原因的基础上,根据实际测量管网数据对水力计算进行参数自适应辨识优化处理,能够离线或在线动态调整节点流量和管道过气能力系数,使水力计算的结果和实际测量数据在一定精度条件下相吻合,有效地解决了燃气管网计算过程收敛速度慢或不收敛的问题,大大减小了燃气管网水力计算的工作量,提高了计算精度和工作效率。Using Visual C＋ ＋6.0 and finite element nodal method,a hydraulic calculation adaptive optimisation simulation software for gas pipe networks has been developed.The principal cause of the difference between hydraulic calculation results of gas pipe networks and actual measured values is thoroughly studied,and based on it,the simulation software performs adaptive parameter identification and optimised processing on hydraulic calculation according to actual measured data.The software can dynamically adjust the node flow and pipeline capacity factor offline or online,so that the hydraulic calculation results and the actual measurement data can coincide in a certain precision condition.The simulation software efficiently solves the problems of slow convergence or divergence in calculation iteration process of gas pipe network,and greatly reduces the workload of hydraulic calculation of gas pipe network,improves the calculation precision and work efficiency.
