Abstract
The aspects of application of hybrid filter-compensating converters for creation on their basis of local sections of power supply, which use parametric filters of currents of zero sequence for creation of artificial neutral in a low-voltage network, in order to provide complex provision of voltage quality parameters at the connection of responsible electric receivers are considered. A simulation model of a three-phase four-wire network with local power supply sites has been created, which allows to estimate the voltage quality parameters when connecting nonlinear and asymmetric loads to it. The simulation results confirmed the efficiency of creating local power systems based on the use of these converters in accordance with the standards of the current international standards for electromagnetic compatibility at the point of connection of a group of responsible electric receivers.
