EXPERIMENTAL ESTIMATION OF THE LAW OF RANDOM PROCESSES DISTRIBUTION IN THE AUTOMATIC CONTROL SYSTEM OF THE GAS PUMPING UNITS OF THE BOOSTING COMPRESSOR STATIONS IN UNDERGROUND GAS STORAGE FACILITY

Abstract

We considered the relevant scientific and practical problem, that is to choose the laws of random processes distribution in the automatic control system of gas pumping units in boosting compressor stations in underground gas storage facility. To resolve this problem we used the experimental data that reflect the parameters which characterize the surge phenomenon in the centrifugal superchargers, such as pressure drop on the narrowing device before the supercharger, the rotation speed of the power turbine, horizontal vibration of the supercharger front support, vertical vibration of the supercharger front support, horizontal vibration of the supercharger back support, vertical vibration of the supercharger back support, pressure ratio. We used the MatLab software package to construct a histogram, theoretical and empirical density distribution. The obtained results were analysed using the equality test and the estimation of the relevant distribution laws was carried out.
