Автономные гибридные электростанции

Автономные гибридные электростанции

Abstract

В статье рассматриваются особенности проектирования и работы в различных режимах функционирования автономных гибридных электростанций на базе возобновляемых и традиционных источников электроэнергии, приведена типовая структурная схема такой электростанции. Показано, что алгоритм работы системы в осенне-зимний период должен корректироваться по данным ежемесячного мониторинга, а генератор резервного автономного источника может запускаться при более глубоком разряде аккумуляторных батарей. Известно, что самым дорогим и при этом самым слабым звеном в составе солнечных фотоэлектрических станций являются аккумуляторные батареи. Кроме того, чем больше их количество в системе, тем усложняется выполнение всех условий правильной эксплуатации. Предложено продлить срок службы аккумуляторных батарей за счёт применения пассивной системы балансировки, позволяющей повысить надежность их работы и снизить стоимость. Показано, что реальной возможностью улучшения технико-экономических показателей автономных гибридных электростанций является выполнение их на базе солнечных фотоэлектрических станций. Рассмотренные в статье особенности построения и работы гибридных электростанций повысят эффективность предпроектных работ по разработке высокоэффективных структурно-схемных решений станций

The article discusses the features of design and operation in the different modes of functioning of autonomous hybrid power plants based on renewable and traditional energy sources. We have given a structural scheme of such a plant. It is shown that the algorithm of the system in the autumn-winter period should be adjusted according to the monthly monitoring; and standby generator of independent source can be run at a deeper discharge of batteries. It is known that the most expensive and the weakest link in the solar PV plants is rechargeable battery. In addition, the larger the number they have in the system, the more complicated the fulfillment of all conditions of proper operation is. We have proposed to extend the lifetime of batteries through the use of passive balancing, which allows to increase the reliability of operation and reduce the cost. It is shown that a real possibility of improving the technical and economic performance of autonomous hybrid power plants is their execution on the basis of solar photovoltaic power plants. We have also discussed the features of construction and operation of hybrid power plants, which will increase the efficiency of preliminary works on development of high-performance structural circuit design of the stations
