Control method and apparatus for active compensation of mains or load-dependent fluctuations in the power flow of an electronic power converter system.

摘要

the erfindungsgemu00e4sse standard procedure serves for active compensation of fluctuations of a leistungsflusses an electronic power konvertersystems. the konvertersystem has a hauptkonverter (2) to transmit power between a dc port and an exit port, and a parallel to the dc port switched buffer capacity c with a pufferkapazitu00e4tsspannung uc.parallel to the buffer capacity c is a compensator (4) connected to the koppelkonverter (41) and an energy storage device (42) which, with the koppelkonverter (41) is established, energy in the energy accumulator (42) to food and this note.in the method, the following steps: determining a hauptkonverter carried out on exit port power supplied pout, ac; determining by the hauptkonverter on exit port power supplied pout.ac *, a sollwertes a compensator (4) to be distributed andtotal power pk, out * and / or a sollwertes for a energiespeicherstrom iu * of the kompensators (4); control of the koppelkonverters (41) so that the compensator (4) emitted or the performance and / or energiespeicherstrom the corresponding set point. the invention relates to a control unit.
