There, the quantity and quality of the natural gas being transmitted are measured. Based on analysis of data on une-ven of transit in the specified direction, they were grouped by quantitative characteristic and the required number of intervals was de-termined. The relative amplitude of gas supply oscillations was calculated and the hydraulic power parameters of gas pipelines were calculated. It is established that the fluctuations of the maximum and minimum hydraulic power for the period from 2015 to 2018 vary within 8.7… 39.5, which indicates significant differences in the modes of operation of the compressor stations and the need to optimize their operation. The relative amplitude of gas supply oscillations was calculated and the hydraulic power parameters of gas pipelines were calculated. On the basis of the review of literature sources on the problem of efficient operation of gas pipelines under conditions of underloading, a technique for determining the capacity and energy consumption of a gas pipeline for a given combination of working gas-pumping units (GPU) was developed. The calculations were carried out for the Ananiev-Tiraspol-Izmail gas pipeline on the Ta-rutyne-Orlovka section. The methodology includes the calculation of the physical properties of gas in its composition, the calculation of gas compression, the calculation of the linear part, the gas consumption for the compressor station's own needs and the calculation of the total power of the gas-pumping units with the given technological limitations. Using the original software developed in the MATLAB programming language, cyclical multivariate calculations of the capacity and energy consumption of the pipeline were performed and optimization of the compressor shop operating modes. For the optimization criterion, the minimum to Product Description popup.authors Vasyliv Oleg B Solodka Antonina V popup.nrat_date 2020-12-03 Close
