Method for earth fault independent compensation of harmonics for the voltages on access points

The method involves using an active, parallel filter, and providing a control to the filter. A desired parameter of the harmonics in a node voltage in a ground connection-independent continuous operation is obtained by supplying of harmonic current. Measurement of the harmonic current to be supplied...

Zusammenfassung:	The method involves using an active, parallel filter, and providing a control to the filter. A desired parameter of the harmonics in a node voltage in a ground connection-independent continuous operation is obtained by supplying of harmonic current. Measurement of the harmonic current to be supplied is implemented based on an adaptive algorithm. Original harmonic voltage is compensated by targeted current supply in ground connection-independent manner via processing of measuring data and using the adaptive algorithm.
