Abstract: The velocity of water hammer wave propagation is one of the main parameters at investigation of unsteady states in the oil pipeline. The velocity parameter is applied in different design hydraulic complexes of Transneft, PJSC - such as, for example, automated system controlling the process parameters of he major pipeline operation, leakage detection system. For oil transfer process calculation based on mathematical models, among others, for increase of the calculation accuracy for transfer transient states, it is necessary to identify the actual velocity of the pressure waves propagation at any point of the linear section of the major pipeline (MP).
For calculation of the parameter of the pressure waves propagation velocity a theoretic formula of N. E. Zhukovskiy can be used. But in practice its application is not always possible, for some of its constituent parameters canТt be defined at the design moment. Existing algorithms for identification of actual velocity of sound wave propagation are, a rule, superficially described, donТt take into account the peculiarities of application and computational complexity of these algorithms, which can lead to significant difficulties and even impossibility of their application in software systems for real-time monitoring of the oil pipeline state. Besides, for such algorithms usually there is no provided description of the results of the algorithms testing on actual data.
In the presented work the authors have developed the algorithm for identification of actual velocity of pressure wave propagation at the linear section of MP. The algorithm is based on the analysis of the readings of successively positioned pressure gages and identification of pressure fronts which are generated at transition modes of MP operation. The work contains a detailed description of the algorithm and presented results of developed algorithm application at PJSC Transneft MP sections.
