Özet
The proposed article is devoted to the assessment of reliability parameters of in-plant power supply systems with 10/0.4 kV double-transformer substations. The paper studies the reliability of the power supply system for the following variants of two-transformer substation schemes: without redundancy; with redundancy when installing a sectional switch; with double redundancy: when installing a sectional switch and a redundant jumper at 0.4 kV. The graphical dependences of operating time to failure of power supply schemes with two-transformer substations on different rated capacity of shop transformers for three variants have been obtained: without redundancy; with redundancy; with double redundancy. The optimum condition is the use of a smaller number of transformer substations, and, accordingly, transformers, while maintaining the value of load factor 0.8. When comparing the graphs, it was found that the longest MTBF is achieved with double redundancy, and the shortest - with no redundancy. The results of the research can be recommended for use in the process of designing systems of in-plant power supply to assess and improve the reliability and efficiency of equipment operation. © 2024 IEEE.
