<p>PCT No. PCT/CA95/00652 Sec. 371 Date Mar. 24, 1997 Sec. 102(e) Date Mar. 24, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/15572 PCT Pub. Date May 23, 1996A method and apparatus for enhancing the capacity of a transformer for a polyphase AC network. The method and apparatus having a constant current transformer branch connected in parallel with at least one conventional transformer branches. The constant current transformer branch includes a phase-shifting transformer in series with reactive elements. Further, for power flow control between two synchronous polyphase AC network busses, two parallel branches are used in which one includes a phase-shifting transformer, while the other includes a reactive element. An additional phase-shifting transformer is added in series with the reactive element to enhance the power flow control flexibility.</p> |
