METHOD FOR CONTROLLING THREE-PHASE VOLTAGE STABILIZER WITH AMPLITUDE-PHASE CONTROL

摘要

stabilization of three-phase voltage of inlet or outlet of main transformer of substation. SUBSTANCE: booster voltage formed by means of recuperative rectifier, voltage inverter and booster transformer is controlled according to two parameters: amplitude and phase. Amplitude is controlled depending upon mains voltage fluctuation. Phase is controlled depending upon load voltage fluctuation. EFFECT: reduced power of booster transformer, enhanced shape of outlet voltage. 1 dwg
