Multi-leak diagnosis in pipelines based on Extended Kalman Filter
A model-based approach to detect and isolate non-concurrent multiple leaks in a pipeline is proposed, only using pressure and flow sensors placed at the pipeline ends. The approach relies on a nonlinear modeling derived from Water–Hammer equations, and related Extended Kalman Filters used to estimate leak coefficients. This extends former results developed for the single leak case, but with the...
متن کاملSmartPipes: Smart Wireless Sensor Networks for Leak Detection in Water Pipelines
Asset monitoring, specifically infrastructure monitoring such as water distribution pipelines, is becoming increasingly critical for utility owners who face new challenges due to an aging network. In the UK alone, during the period of 2009–2010, approximately 3281 mega litres (10) of water were wasted due to failure or leaks in water pipelines. Various techniques can be used for the monitoring ...
متن کاملINVERSE FREQUENCY RESPONSE ANALYSIS FOR PIPELINES LEAK DETECTION USING THE PARTICLE SWARM OPTIMIZATION
Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...
متن کاملTechnology Status Report on Natural Gas Leak Detection in Pipelines
However, any opinions, findings, conclusions, or recommendations expressed herein are those of the author and do not necessarily reflect the views of the DOE". Natural gas consumption in the US is expected to increase 50% within the next 20 years (Anderson and Driscoll, 2000). At the same time, the gas delivery infrastructure is rapidly aging. The Department of Energy has stated that ensuring n...
متن کاملLeak Detection Methods in Transmission Pipelines and Error Sources
Leak detection in transmission pipelines is important for safe operation of pipelines. The probability of leaks may be occurred at any time and location, therefore pipeline leak detection systems play a key role in minimization of the occurrence of leaks probability and their impacts. Today there are many available assortments of modern technologies in the domain of leak detection. This paper p...
