Reactive Power Control of Reversible Electric Drives by Using Industrial Smart Grid Technology

Abstract

This paper addresses the issue of associating a concept of industrial smart grid technology for a reactive power control of reversible electric drives. The research focus was concerned with the theoretical analysis of active, reactive and apparent power by the main reversible electric drive of plate mill rolling stand. Typical features of power electric equipment of modern reversible electric drives allow us to develop the reactive power control. The reactive power control can be created out by using of back to back converters which connect the reversible electric drive with the supply mains. Experiments in the plate mill were carried at the difficult-to-form steel grade in the range of roughing and finish rolling. It was established that the reactive power generation can be used in the range of the roughing. The huge prospects of the reversible electric drives integration based on back to back converters in Industrial Smart Grid have been determined due to the fact that to control of reactive and apparent power flows.
