METHOD FOR INTERCONNECTING TWO SYNCHRONOUS POLYPHASE AC NETWORKS AND INTERCONNECTING APPARATUS FOR THE SAME

摘要

The 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 ea ch phase line of the first AC network (a) connecting a first one of a first susceptance to the phase line of the first AC network; (b) connecting a first end of a second susceptance to the phase line of the first AC network; (c) applying to a second end of the first susceptance a first phase voltage derived from the second AC network; and (d) applying to a second end of the second susceptance a second phase voltag e derived from the second AC network. the second phase voltage being phase shifted with respect to the first phase, voltage. One of the susceptances is inductive and the other of the susceptances 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. These is also provided an interconnecti ng apparatus for the same purpose.
