PCT No. PCT/CA91/00041 Sec. 371 Date Nov. 8, 1994 Sec. 102(e) Date Nov. 8, 1994 PCT Filed Jan. 26, 1994 PCT Pub. No. WO94/17579 PCT Pub. Date Aug. 4, 1994The method of interconnecting first and second synchronous polyphase AC networks is for regulating transfer of active power from one of the AC networks to the other. The method involves the steps of, for each phase line of the first AC network, connecting a first end of a first reactive element to the phase line of the first AC network; connecting a first end of a second reactive element to the phase line of the first AC network; applying to a second end of the first reactive element a first phase voltage derived from a second AC network; applying to a second end of the second reactive element a second phase voltage derived from the second AC network, the second phase voltage being phase shifted with respect to the first phase voltage. In a preferred method according to the invention, one of the reactive elements is inductive, and the other of the reactive elements is capacitive. In operation, a phase shift between the first and the second phase voltages forces a regulated transfer of active power from one of the AC networks to the other. Also provided is an interconnecting apparatus for the same purpose.
