Various transient test-based techniques have been developed for detecting leaks in pipeline systems, and most of these depend on a signal that is reflected by the leak. In field pipes, this signal is easily disturbed by high frequency noise, which can prevent detection. This paper presents a leak detection method using transient pressure damping by energy dissipation from the leak, which is minimally affected by the noise. The numerical simulation confirms that the method can be applied within the range of practical pipe scales, provided that the flow rate is reduced by restricting the valve. The model is verified, and leak location is estimated within an error of <6% of the total length despite the noise from the loops. This method offers a simple and easy means to detect leaks without numerical simulation, although it is limited to single pipeline systems.

已经开发了各种基于瞬态测试的技术来检测管道系统中的泄漏，其中大多数依赖于泄漏反射的信号。在现场管道中，这种信号很容易受到高频噪声的干扰，从而阻碍检测。本文提出了一种通过泄漏能量耗散使用瞬态压力阻尼的泄漏检测方法，该方法受噪声影响最小。数值模拟证实，该方法可以在实际管道规模范围内应用，前提是通过限制阀门来降低流量。该模型经过验证，尽管存在环路噪声，但泄漏位置的估计误差小于总长度的 6%。这种方法提供了一种无需数值模拟即可检测泄漏的简单易行的方法，
