Verfahren zur Verbesserung der Spannungsqualität in einem Drehstromnetz und Anlage für die Durchführung des Verfahrens

The method employs reversible AC-DC convertors (2.1-2.3) connected between the respective phase lines (U,V,W) and a common energy store (3) such as a battery of accumulators or a superconducting magnet. The instantaneous line voltage is detected and applied to a computer (4) which works out an ideal...

Beschreibung
Zusammenfassung:	The method employs reversible AC-DC convertors (2.1-2.3) connected between the respective phase lines (U,V,W) and a common energy store (3) such as a battery of accumulators or a superconducting magnet. The instantaneous line voltage is detected and applied to a computer (4) which works out an ideal value for the voltage in real time. The reversible convertors are controlled by a regulator (5) in accordance with the difference between the instantaneous actual and ideal voltages. The computer works on a band-pass model comprising two successive filter sections, the first having series resistance and inductance with shunt capacitance, and the second section having series resistance and capacitance with shunt inductance.
