Оценка экономической эффективности электроснабжения на основе постоянного тока

Abstract

Целью работы является анализ экономической эффективности электроснабжения на основе постоянного тока. Для решения поставленной цели необходимо решить следующие задачи: 1. Провести анализ применения технологии постоянного тока в мире и в России. 2. Оценить возможные риски применения технологии постоянного тока. 3. Определить факторы, влияющие на целесообразность применения технологии постоянного тока. 4. Провести расчет и оценку экономической эффективности электроснабжения на основе постоянного тока. Актуальность работы в первую очередь связана с тем, что в настоящее время широко строятся и проектируются линии постоянного тока по всему миру. Несмотря на то, что на сегодня в отечественной электроэнергетике отсутствуют какие-либо проекты на основе постоянного тока кроме ВПК, рассмотрение таких проектов остается актуальным. Кроме того, в нормативно-технических документах, которые регламентируют подходы к проектированию, развития Единой электроэнергетической системы России предписывают рассматривать варианты постоянного тока наравне с вариантами строительства электропередач переменного тока, и выбирать приоритетный вариант на основе соответствующего технико-экономического сравнения. Примером такого сравнения вариантов электропередачи на основе постоянного и переменного тока посвящена данная работа. Источниками информации выступили данные отечественной и зарубежной научно-исследовательской литературы, официальных Интернет-ресурсов. Оценка экономической эффективности проекта проводилась с помощью пакеты MS Office (Excel).

The purpose of the work is to analyze the economic efficiency of DC-based power supply. To achieve this goal, it is necessary to solve the following tasks: 1. To analyze the application of DC technology in the world and in Russia. 2.To assess the possible risks of using DC technology. 3. To determine the factors influencing the feasibility of using DC technology. 4.To calculate and evaluate the economic efficiency of power supply based on direct current. The relevance of the work is primarily due to the fact that DC lines are currently being widely built and designed around the world. Despite the fact that today there are no DC-based projects in the domestic electric power industry except for the military-industrial complex, consideration of such projects remains relevant. In addition, the regulatory and technical documents that regulate approaches to the design of the development of the Unified Electric Power System of Russia prescribe to consider DC options on a par with options for the construction of AC power lines, and to choose a priority option based on an appropriate technical and economic comparison. This work is devoted to an example of such a comparison of power transmission options based on direct and alternating current. The sources of information were data from domestic and foreign research literature, official Internet resources. The economic efficiency of the project was assessed using MS Office (Excel) packages.
