Estimation of reliability factors of independent power supply devices in remote linear facilities of Eastern Siberia and Far East main gas pipelines
Abstract
The authors have carried out the statistic analysis of typical emergencies at independent power supply sources in remote linear facilities of Eastern Siberia and Far East main gas pipelines by the example of 101 self-contained power stations operating using Rankine organic cycle. Three main reasons of emergencies at the power stations: burner device loss of flame, turbine unit mechanical failure and extreme temperature in a condenser were determined. The integral reliability parameters of the power supply sources (failure flow and intensity) were calculated for the given reasons. The authors compared the obtained values of reliability parameters of power station operation with manufacturer values and developed the recommendations for increasing integral reliability parameters of operation of independent power stations intended for power supply of remote linear facilities of main gas pipelines in Russia.
