Abstract:
Leak detection system 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 study provides the proper methodology to
facilitate the choice of leak-detection system. The study deals with external
methods based on external measurements such as acoustic emissions, cable
sensors, liquid sensing and vapor sensing and with some internal methods based
on flow and pressure measurements in the pipeline: volume or mass balance
method, pressure wave detection method, and real time modeling were
described. Additionally, the discussion of error sources and final conclusions are
presented.
This study is provided by simulation for one of leak detection method
which is pressure wave detection by using CitecSCADA from Schneider
Electric.
