Electromagnetic Compatibility research of TVR for distribution networks 6-20 kV
In the article was made a research of electromagnetic interference in the form of non-sinusoidal voltage. Such electromagnetic interference is generated when thyristor voltage regulators are operated in MV distribution electrical networks. In their research, a calculated and analytical model was used of the device developed by the authors. It has been established that in all modes of operation of the device, the values of the harmonic components of the voltage and the non-sinusoidal voltage coefficient do not exceed the established standards. The approximating expressions for calculating the harmonic currents generated by the device are proposed, allowing to calculate the non-sinusoidal voltage when the device is operating in the electrical network without prior modeling.
