| 摘 要： | 本文研究了基于恒定流动模拟的静态泄漏检测方法和基于水力瞬变模拟的瞬变泄漏检测法，分析了瞬变泄漏检测法用于热力管网的可行性，建立了瞬态泄漏检测法的数学模型，误差准则，以及泄漏位置的确定方法，并通过实际供热管网泄漏检测数值仿真作了比较，表明用瞬态泄漏检测法可显著改善热网微机监控系统泄漏检测的能力。

| Abstract: | This artical investigates two methods which are applicable to the leak detection of heating distribution networks.The first method is based upon the simulation of the steady-state flows and the second one is based upon the simulation of hydraulic transients.The error criterion and method are presented for determining the leak position in the networks.The application of these two methods to a practical network shows that the second method is much more effective than the first one. |
