| description | The invention relates to an adaptive system for ensuring a certain quality of energy in low-voltage networks. According to the invention, the system consists of a first active filter (A) connected in parallel with the electric network and with a load (B) comprising a voltage inverter (101), three induction coils (108, 109 and 110) and three resistors (111, 112, 113) connected in the same point with the load (B), a measuring block (118) for the load currents, a measuring block (119) for the currents at the inverter output, a three-phased contactor (122) for connecting/disconnecting the system to/from the network and a second active filter (C) which comprises an inverter (102), a sinusoidal filter (104), three single-phase transformers (105, 106, 107) connected in series to the distribution network and a measuring block (115) for measuring the inverter output voltages.
Invenţia se referă la un sistem adaptiv pentru asigurarea calităţii energiei în reţelele de joasă tensiune. Sistemul conform invenţiei este compus dintr-un prim filtru activ (A), conectat în paralel cu reţeaua electrică şi cu o sarcină (B), cuprinzând un invertor de tensiune (101), trei bobine inductoare (108, 109, 110) şi trei rezistoare (111, 112, 113) conectate în acelaşi punct cu sarcina (B), un bloc (118) de măsurare a curenţilor de sarcină, un bloc (119) de măsurare a curenţilor la ieşirea invertorului, un contactor trifazat (122), pentru conectarea/deconectarea sistemului la/de la reţea, şi un al doilea filtru activ (C), cuprinzând un invertor (102), un filtru sinusoidal (104), trei transformatoare monozate (105, 106, 107), conectate în serie la reţeaua de distribuţie, şi un bloc (115) de măsurare a tensiunilor de ieşire din invertor. |
