ABB UNITOR1000-7 Compact AVR Excitation Controller
ABB UNITOR1000-7 belongs to the UNITOR1000 series compact synchronous generator automatic excitation regulator (AVR excitation controller), which is the core unit of excitation control for synchronous generator sets. UNITRAL1000-7 real-time collects generator terminal voltage and current signals, automatically adjusts excitation output current, and stabilizes generator output voltage; Built in power system stabilizer PSS suppresses low-frequency oscillations and enhances the stability of grid connected units. Simultaneously integrating a complete set of generator protection logic for over excitation, under excitation, overcurrent, demagnetization, etc., supporting unit grid connection and disconnection control, suitable for 100kVA~80MVA synchronous generator sets, mostly used for excitation control of synchronous machines in land power stations and ship power stations.
