| Summary: | The trouble-free operation of the power supply system elements of plywood
production largely depends on maintaining the required quality of electric energy.
It is essential to focus on calculation of higher harmonics mode at engineering
the power supply system of plywood production, as the process uses powerful
semiconductor controlled rectifiers. The article discusses the controlled rectifier
that is required for the operation of a four-foot veneer peeling machine.
The authors determine that the presented unit generates higher harmonic currents
into the network. These currents negatively affect all elements of the power supply
system. However, there is no calculation method for the mode of higher harmonics
in the power supply system of plywood production. Therefore, the purpose of
the research is to develop a methodology for calculating the mode of higher
harmonics in electrical networks of plywood production. The experiment was
conducted at an operating plywood production in the Kirov region to achieve
the research purpose. The investigation object was a four-foot veneer peeling
machine. It was found that the higher harmonics generated by the main drive of
the veneer peeling machine change randomly. The authors proposed to consider
them as random variables in the calculations. The research determined statistical
laws of the higher harmonics distribution and their numerical features. The authors
obtained analytical expressions for calculating the amplitudes of the higher
harmonics through the amplitudes of the main harmonic component of the current in
the absence of information about the control and switching angles of the rectifier.
The proposed technique allows calculating amplitude spectra of higher harmonic
currents in branches and voltages in nodes of the power supply system of plywood
production. According to the proposed methodology, the results of calculations are
recommended for solving series of practical problems. |
