Probabilistic-statistical analysis of power and energy distortion in an electric network with non-sinusoidal supply voltage

The results of experimental studies of power and distortion energy (PDE) generated by enterprises with non-sinusoidal supply voltage of the industrial area are presented. A brief analysis of the reliability of equipment and devices of power supply systems (PSS) exposed to the impact of non-sinusoidal voltage (NSV) is given. The random nature of the NSV indicators causes random changes in the PDE. A probabilistic-statistical analysis of the PDE components that cause a change in the energy of the fundamental harmonic oscillation and distortion of its sinusoidal shape is given. The results of studies of parallel operation of NSV sources, features of changes in amplitudes and angles of harmonic shift, and total PDE are given. The issues of modeling non-sinusoidal modes at an arbitrary point of the PSS are considered, and a new calculation algorithm is recommended.
