Analysis of power supply systems reliability for gas pumping compressor stations

Failures statistic data of power supply systems' elements for gas pumping compressor stations are processed in this paper. The distribution functions of operating time between failures, operating time between unplanned repairs, restoration time are chosen for power supply systems' elements. Parameters of Weibull distribution function are determined. The reliability of power supply system for gas pumping compressor station is simulated. Comparative analysis of the system reliability with hot and cold reserve is processed. The role of elements and it's parameters for ensuring reliability are determined. The rational boundaries for increasing of reliability for the most important system elements are determined.
