System for electrical energy quality improvement

摘要

the system consists of parallel compensation active filters in each conduit coupling containing phase and an energy electronic converter ac / dcand / or from the system dynamic reproduction voltage containing in each phase line filter transformer and coupling (3, 4, 5), (7, 8, 9) and energoelektroniczne ac / dc converters.and energy reserve in the form of storage capacitor c1 set to clamp stałoprądowe listed converter.in each phase the filter coupling type lclr each of resistors is replaced by an energy recovery system consisting of półmostkowego energoelektronicznego adapter(16, 17, 18) (26, 27, 28) connected through reactors and block measuring voltage and current (13, 14, 15) (23, 24, 25) to filter the coupling in place of his principal rezystora,and signal wires block measuring voltage and current are attached to the adapter.in the parallel compensation actively to both leave each fittings are attached in series connected capacitors (c2, c3) constituting the intermediate reservoir energyand by an energy electronic converter (22), with galvanic isolation circuit input circuit from the output dc / dc, to terminals of storage capacitor (c1).a point of capacitors (c2, c3) is attached to the neutral (n) blocks and by measuring voltage and current to one of the out coupling filters (3, 4, 5).in the system dynamic reproduction voltage to both leave each of energoelektronicznych (26, 27, 28) for each phase separately.attached are in series connected capacitors and by individual converters (32, 33, 34) to a storage capacitor (c1).accordingly, in each phase, the common capacitors is attached, by measuring the voltage and current to block one of the out coupling filter (7, 8, 9).
