The follow-up circuit of basic harmonic wattless power compensation with adjustable value together with filtering of higher harmonic in the medium or high voltage power grid

摘要

nadu0105u017cny system reactive power compensation basic harmonic of adjustable value, together with the higher harmonic filtration in medium or high voltage electricity network is characterized by the fact that consists of the transformer power supply (1), a filtering (2) on one winding of more average (sn) or a high voltage (argued) and one low voltage coils (nn)accompanied by the low voltage winding via of thyristor (3) equipped with two triacs capacitor banks (4) connected in a triangle, the triacs are connected in any two phase and the third phase is connected directly to the capacitor (4).
