Analysis of non-sinusoidal operating modes of electrical equipment in electrical supply system with 6-pulse transducer

Abstract

The subject ofresearch: In the article was made the analysis of non-sinusoidal operating modes of electrical equipment in a power supply system with 6-pulse transducer. Methods and objects of research: The analysis was based on 3 experiments. In the first case, the system of power supply without devices of compensation of currents of higher harmonics was considered. In the second case, the system was simulated with static capacitor banks. In the third case, a power supply system with a tuned filter to the 5th harmonic was considered. Results of research: Based on the conducted experiments, results were obtained showing that in the presence of higher harmonics in the network and when static capacitor banks are installed, resonance is observed at the 5th harmonic. When installing a tuned filter, the voltage in the network is normalized and is at the required level in accordance with GOST 32144-2013.
