Abstract
В роботі проаналізовано використовувані методи та
шляхи підвищення ефективності передачі електроенергії в
повітряних лініях електропередачі. Розглянуто роль та
місце електричної енергії в загальній структурі енергоспоживання, способи її транспортування, види втрат, які
виникають під час транспортування електричної енергії, та
шляхи зменшення цих втрат. На підставі літературних
джерел досліджено структуру втрат в лініях передачі. У
проведеному огляді літератури вказується, що не розглядався такий вид втрат, як втрати за рахунок неузгодженості навантаження з лінією. Проаналізовано шляхи
досягнення та можливості підтримання роботи лінії в
режимі узгодженого навантаження.
At this article, existing methods and ways to increase the efficiency of electricity transmission in overhead power lines were analyzed. The role and place of electric energy in the general structure of energy consumption, methods of its transportation, types of losses that occur during transportation of electric energy and ways to reduce these losses were considered. On the basis of literature sources the structure of losses in transmission lines was investigated. A literature review indicates that a certain type of losses has been overlooked, that is, losses occurring due to the mismatch of the load with the line. The ways of achieving and possibilities of maintaining the operation of lines in a matched load mode were analyzed. New method of reducing losses by creating a matched load mode in power lines is proposed.
