Abstract
Abstract According to the invention, the arrangement for limiting dynamic overvoltages in a long-distance power transmission line for commercial-frequency current, interconnecting a transmitting power system and a receiving power system, includes batteries of static capacitors and switching devices connecting these batteries of static capacitors to the power transmission line the moment relative swinging of the power systems occurs, at points spaced, respectively, from the transmitting power system and from the receiving one by a distance of which the wavelength equals one half of the wavelength of the commercial-frequency voltage. The disclosed arrangement enables to limit the dynamic overvoltages without affecting the level of the dynamic stability of the interconnected power systems.
