Assurance of electromagnetic compatibility of group frequency controlled electro drives with power supply sources

摘要

Experience of creation and implementation of gas cooler with the frequency-regulated electro drive of fans shows a necessity of measures to the assurance of electromagnetic compatibility of the frequency-regulated electro drives with a power supply sources. On certain quantity of concurrently running gas coolers with frequency-regulated electro drive of fans the significant distortion of voltage curve form occurs in grid. The problem becomes more serious in case of autonomous power supply sources. The ways of problem solving of assurance of electromagnetic compatibility of the frequency controlled electro drives with a power supply sources introduced in this paper. Described results reached by mathematical modeling MATLAB+Simulink.
