DEVICE FOR CONNECTING TUNED POWER TRANSMISSION LINE TO A.C. NETWORK

摘要

The proposed device for connecting a tuned power transmission line to an a.c. network comprises the following units that are seriesly interconnected in any combination: a phase transposition unit for phase shifting of voltage through an angle which is multiple to the natural shift of voltages of opposite phases, a coupling transformer with a switchable group of connections of its windings, which transformer matches the voltages of the tuned power transmission line and the a.c. network and effects a phase shift of voltage which is multiple to 180.degree., and a transverse voltage regulation transformer which makes it possible to smoothly change the voltage phase shift under load. The device for connecting a tuned power transmission line to an a.c. network ensures parallel operation of the tuned power transmission line and the a.c. network, as well as mutual reserving of the generators of the tuned power transmission line and the local power system.
