The arfticle gives the new concept on electric energy trasferring over long-distance an AC overhead high voltage transmission line (TL). It is based on the applying of transmission lines of increased natural power, controlled reactors and doublefeed synchronous machines (asynchronized synchronous generators ASG ). The reactors are means of voltage regulation in Intermediate points of line while normal and emergency conditions and static stability provision. Asynchronized synchronous generators while operation in initial regime with little initial negative slipping and special excitation control law allow to Increase the level of TL dynamic stability.
