Combination of power electronics systems regulated by harmonic filtration and / or reactive power compensation supplying a controlled unit for the production of hydrogen and oxygen by electrolysis of water

摘要

The invention relates to an electrical installation comprising at least one harmonic polluter and / or a large consumer of reactive energy, to which is added at least one active harmonic filter at a suitable voltage level and configured to compensate for the undesirable current distortion and / or or allow compensation of the reactive energy absorbed from the network. By a 3rd regulation loop, the voltage and the capacitance of the DC bus of the harmonic filter is adapted to allow the connection of a set of electrolysis cells on its DC bus thus enhancing the available charge rate of the filter (s) in function. the operating points and the variable absorption spectrum of the polluter, the configurations of the upstream network, the aging coefficients and the standard sizing margins by the production of hydrogen by electrolysis of water.
