Abstract :
The work reports on studies, which supported the projecting, reconstruction and modification of a 750 kV, 479 km long transmission line. The changes were demanded by the technical development and the alteration of the role of the line in the power transmission. Authors analyse various ways for influencing on the interaction of the reactive power control, relaying and overvoltage protection. The possibility of the operation with incomplete, asymmetrical shunt reactor and arrester sets is investigated. The paper describes a simple way of controlled three-phase and adaptive single-phase reclosure.
