On Some Useful Qualities of 12-Phase Converters with a Controllable Ensemble of Harmonics in a Compensating Device Common for Six-Phase Units

摘要

The circuitry of one of the 12-phase converters with reactor control of an ensemble of current and voltage harmonics in a compensating device common for two six-phase units is set out. Time diagrams and basic characteristics of the converter are presented. The advisability of using converters with an ensemble of odd harmonics is shown for the consumers of the direct current power located in a region adjacent to a power supplier. For distant power consumers, use of converters with an ensemble of even harmonics is suggested. For the purpose of improving the stability of the inverter regime when recovering electric power into the supply mains, the practicability of using thyristor converters with an ensemble of even harmonics is demonstrated. Some examples of engineering and design solutions are presented by the example of a compensating device reactor for a converter with an ensemble of odd harmonics.
