摘　　要：介绍了GNET软件的特点、用途,根据广东省某市城区中压燃气管网的实际情况,对设计工况及事故工况下的管网运行状况进行了模拟计算。针对模拟计算结果,对该城区中压燃气管网的可靠性进行分析并得出在该城区管网中设置环网和多个气源时,管网可靠性较高的结论。In this paper, both features and functions of GNET software are presented. And based on the real situation of domestic gas networks with medium voltage in one city of Guangdong province, their operation under not only design condition but also accident condition is simulated and calculated. After that, their reliability is also analyzed and a conclusion is made that ring network and many gas resources should be equipped with to achieve a high reliability. This conclusion can be applicable to smallto mediumsized cities. Meanwhile, some suggestions on the network reliability are also made.
