Power circuits and methods for controlling regulated filter sensors and static synchronous reactive power compensators for the development of modern hybrid filter-compensating transducers have been developed. The power circuits of hybrid filter-compensating converters for three-phase four-wire systems with nonlinear and alternating loads at complex improvement of electric power quality are developed, and with the help of developed specialized simulation models the efficiency of their application is investigated. With the help of developed specialized simulation models, the research of complex provision of electromagnetic compatibility in local electric networks was carried out with the use of developed hybrid filter-compensating converters. The scientific novelty of the results obtained is as follows: 1. The principles of construction of hybrid filter-compensating converters, which consist of combining the functional capabilities of regulated filter-symmetrycal device and "distributive" D-STATCOM or multifunctional reactive power compensators, are developed. 2. Based on the new developed simulation model of hybrid filter-compensating converters with "distributive" D-STATKOM the efficiency of its use has been proved to bring the electricity quality indices in three-phase four-wire systems to the values normalized by the current international standards with EMC. 3. For the first time, the use of hybrid filter-compensating converters for the creation of local power supply systems with a separation from the main circuit of the circuit for the flow of currents of zero sequence, which can significantly improve the quality of electrical energy and reliability of power supply of responsible customers in fulfilling the requirements defined by the current standards of EMC. Field of application - electric power. Product Description popup.authors Малахатка Денис Олександрович popup.nrat_date 2020-04-02 Close
