FIELD: automatic control of electrical equipment to ensure electromagnetic compatibility of power supply equipment characterized in comparable supply mains and load power capacities. SUBSTANCE: method involves control of motor operation with subordinate current regulation and limiting. Current is limited depending on supply voltage deviation from rated value. EFFECT: reduced voltage drop across supply mains and voltage deviation and variation across load terminals due to reduction of degree of current limiting in case of voltage decrease in supply mains. 3 dwg
