Abstract
This work presents two methods for double leaks detection in liquid transmission pipelines. They may be used to detect both two simultaneous leaks and non-simultaneous ones. The first method is based on the pipeline’s static model with two leaks and minimization of the objective function, which is determined as the square deviation between modeled pressure and pressure measurements taken from the pipeline. The second method uses the pipeline’s static model, gradient index functions for leakage detection and algorithms to determine leaks’ location and size. Both methods were verified with measurements, gathered from the experimental pipeline to transmit water. The study results confirmed the highly satisfactory effectiveness of both proposed diagnostic methods.
