Flexible Systems for the Transmission of Electrical Energy Over Long Distances

Abstract

Object: Transport of electrical energy over long distances based on flexible power transmission systems using a thyristor voltage regulator. Methods: Transportation of electric power of an alternating current to ultra-long distances is possible by compensating or half-wave (tuned to half-wave) power transmission. Findings: In order to transmit electric power with alternating current to long-distance and ultra-long distances, half-wave power transmission should be preferred, since they do not require additional costs for reactive power compensation and, at the same time, have increased capacity. However, the advisability of tuning to a half-wave occurs when the line length is 1500 km or more. The line, which is less than 1500 km long, should be brought to the line of “zero length”. The reactance of the line, the length of which is less than the boundary length, that is, less than 1500 km, is proposed to be compensated and lead to a “zero” length line to increase throughput and stabilize the voltage regime along the line with the help of a thyristor parameter stabilizer developed at the Institute of Physical and Technical Problems of the North them.

Conclusions: A trunk line is proposed in the north, providing the centralized electricity supply to the new industrial centers of the northern and arctic regions of the Republic of Sakha (Yakutia). A new method for constructing extended power transmission in an understated voltage class based on high-current electronics was developed.
