| description | The relevance of the research is caused by the need to improve the quality factors of output voltage and current of voltage inverters in electric submersible pumps, used in oil production. The main aspects, which allow improving these quality factors are: usage of perspective topologies of power part and modern power semiconductor keys, implementation of new control algorithms. In electric drives, where frequency converters are used, there are negative factors, affecting oil-submersible cable and submersible induction motor functioning. Non-sinusoidal voltages at the frequency converter output lead to increased wear and tear of the supply cable insulation, and also negatively affect the insulation of induction motor windings and reduce the quality indicators of electric drive control systems. Consequently, the search for ways to improve the quality of the output voltage and current of the voltage inverters in electric submersible pumps is a critical task. The main aim of the research is to develop the algorithms to improve the reliability indicators of multilevel converters and upgrade the quality of harmonic composition of the output voltage and current of voltage inverters as part of the electric drive of a submersible oil-producing pump. Object: voltage inverters as a part of electric drive of submersible oil producing pump. Methods and tools: reliability theory, harmonic analysis, functional diagrams, switching functions, topology of electric circuits of power converters, numerical methods for solving differential equations, fast Fourier transform, Matlab Simulink. Results. Significant improvement of current and voltage quality factors in multilevel converters as a part of electric drive of submersible oil-producing pump has been demonstrated. Possible ways to improve reliability indicators by changing the layout option of the circuit topology have been considered, with the probability of no-failure operation increasing from 23,70 to 66,10 % as compared to the classical layout. It is established that regulation of switching frequency depending on operating modes in multilevel inverters will allow controlling rationally dynamic losses and loads on power keys. |
