Modeling of resonance of currents on higher harmonics with non-stationary mode of power supply system operation
The article describes the simulation of the current resonance that occurs in the power supply system when the degree of reactive power compensation is varied in non-stationary operation modes and the presence of electric receivers having a nonlinear voltagecurrent characteristic. In addition to s...

| Summary: | The article describes the simulation of the current resonance that
occurs in the power supply system when the degree of reactive
power compensation is varied in non-stationary operation modes
and the presence of electric receivers having a nonlinear voltagecurrent characteristic. In addition to simulating the mode of
parallel resonance arising at frequencies close to the frequencies of
higher harmonics, the proposed algorithm determines all possible
resonance frequencies at which the parallel resonance condition
under different assumptions can be satisfied, as well as the relative
error of calculation for different cases: when all the components
of complex impedances are taken into account; without taking
into account the active components of the resistance; taking into
account the active component of the resistance of the transformer,
but not taking into account the resistance of the loads; without
taking into account the active component of the resistance of
the transformer and without taking into account the resistance
of the loads. The purpose of the proposed work is to show how
the accounting (non-accounting) of the components of complex
resistances affects the results of determining the resonant
frequencies. |
