<p>PCT No. PCT/AT94/00028 Sec. 371 Date Sep. 13, 1995 Sec. 102(e) Date Sep. 13, 1995 PCT Filed Mar. 17, 1994 PCT Pub. No. WO94/22200 PCT Pub. Date Sep. 29, 1994A synchronizing device for a parallel connection of a synchronous generator and an a.c. network. The device includes a measuring circuit for measuring the voltage and frequency of the generator and the a.c. network and for measuring the phase angle between the generator and the a.c. network. The measuring circuit includes control outputs for regulating the rotational speed of the generator drive. A set value for the generator frequency includes a defined slip at the start of balancing. The measuring circuit also regulates the voltage output of the generator to match the a.c. network voltage. Once the phase angle between a.c. network voltage and generator voltage has fallen below a predefined value, null balance occurs.</p> |
