This paper describes a method to provide LV four-wire three-phase power converters with the capability of correcting unbalance as an ancillary service to the main role that they play in the distribution system (distributed generator, energy storage system, drive, etc). Typically, dedicated grid/load current sensors are needed to effectively comply with unbalance compensation tasks, increasing system...
In this article an energy management strategy for a Modular Multilevel Converter is proposed, this converter is operating as a direct frequency changer. It is connected in three-phase configuration and the developed control strategy depends only on measurements made at the converter site without using neutral wire parameters information, which is convenient for high power applications. Developments...
The paper presents the results of the experiments aiming at the quantitative assessment of the adverse effects that arise when the electric drive is powered by the alternating current (AC) power via a long cable. For elimination of negative influences were used various types of output EMI (electromagnetic interferences) devices. It was studied, how much mention devices reduce interfering influences...
Several methods have been proposed for the measurement of the magnetic losses in electrical steel sheet in a rotating magnetic flux. The method considered here is based on determination of the field quantities and makes use of square specimens and an air gap between the pole faces and the specimen. We earlier reported the results of magnetic field analysis on this apparatus by the finite element method...
