Abstract
The methodology for calculating the reliability of power supply systems with autonomous and mixed energy sources has been considered. Autonomous sources are widely used in industrial power supply systems as primary, backup or emergency sources. The functioning and interchangeability of these systems has features that affect the reliability of power supply. The proposed methodology is based on the method of semi-Markov random processes and can be used for comparative analysis of the reliability of options for power supply systems. The methodology has been brought to software implementation and is accompanied by an example of calculating the reliability of the power supply system for stationary marine oil production platforms.
Highlights
Objects of production, transportation and refining of oil and gas are complex continuous production, which put increased requirements for the reliability of power supply [1,2,3,4]
For a comparative analysis of the reliability of options for power supply systems, a technology based on the mathematical method of semi-Markov random processes is proposed [5,6,7,8]
Along with failures of elements and failures in the operation of the reserve input, it is necessary to take into account the possibility of system failures, which may be due to interruptions in the supply of fuel to generating electrical units and the failure of relay protection of power supply systems
Summary
Transportation and refining of oil and gas are complex continuous production, which put increased requirements for the reliability of power supply [1,2,3,4]. For a comparative analysis of the reliability of options for power supply systems, a technology based on the mathematical method of semi-Markov random processes is proposed [5,6,7,8]. Along with failures of elements (sources, lines) and failures in the operation of the reserve input, it is necessary to take into account the possibility of system failures, which may be due to interruptions in the supply of fuel to generating electrical units and the failure of relay protection of power supply systems. The Gauss method is used to solve the system of equations
