Abstract
The RELEVANCE of this study is to develop a computer model for assessing and predicting the reliability parameters of power supply system circuits for facilities with 10/0.4 kV transformer substations.
METHODS: Reliability theory and probability theory methods were used in the research. The parameters of power supply circuits were modeled in Matlab/Simulink to study key reliability indicators (such as the circuit failure rate parameter (ωcircuit), mean time between failures (MTBF), probability of failure-free operation (P), and probability of failure (Q). Twelve computational experiments were conducted with varying initial parameters for circuits of various configurations.
RESULTS. The results of computational experiments using the developed model in Matlab/Simulink are presented. They were used to estimate the reliability parameters of power supply circuits – ωcircuit, TBF, P, and Q – with varying initial data.
CONCLUSION. The paper presents the results of modeling in Matlab/Simulink. The obtained results can be recommended for use in the design of power supply systems. Application of the developed model in the design and operation of power supply systems at facilities allows for the assessment of circuit reliability parameters and the management of the reliability of power supply to consumers while ensuring the efficient operation of electrical equipment.
