FIELD: electrical engineering. SUBSTANCE: at first stage of starting of electric transmission switches 2 and 12 are cut in and inverter 16 is under shunting condition. Current in A C link grows slowly thanks to reactors 8 and 17 and in additional circuits thanks to use of valves 6 under condition of A C stabilizers. This results in decrease of starting overvoltages. Then C link is cut in by closure of short-circuit switch 7 and switches 4 and 14. EFFECT: enhanced reliability of electrical transmission of pulsating current at starting stage. 3 dwg
