Increase of Electromagnetic Compatibility of the Rotary Type Electromagnetic Separator with Semiconductor Current Regulators
Abstract
The separation subsystem was developed, which allows improve the compensation methods of current non-active components under the nonlinearity of the load, like a rotary type electromagnetic separator. It is realized by the excluding of the harmonic voltage components, caused by distortion of the network, of forming the compensation currents. It allows to increase the efficiency of the power supply systems and to improve the performance of the compensation system. A new method of optimal magnetization windings current and performance control using fuzzy logic was developed. It has the following optimal criteria: minimum power consumption, maximum efficiency, maximum quality of consumption current for a given output quality and the fuzzy proportional-integral current control method in magnetization windings electromagnetic separator. The appropriate ranges of variation and functional correlations of the parameters of the universal current harmonics filter were determined for various nominal input currents of the system, thanks to which filters were developed that reduce the level of current harmonics consumed by the system from the network.
