配管中の漏れの位置と大きさを過渡圧力変動の計測値から推定する方法を提示した。Leak detection for leaks at two points was done using the inverse transient method and genetic algorithm.The locations and discharges of each leak were selected as GA parameters for leaks at two points in pipeline.The steady pressures and leak discharges at all nodes were calculated using Newton iteration method.Calculations under assumption of two leaks points were done for not pnly leaks at two points but also leak at one point in pipeline.Furthermore,the effect of noise in pressure data was discussed,and the leak locations and leak discharges can be predicted precisely even in the case of noisy data.
