摘要

现代连续照明系统使用强大的高性能led作为光源,一项重要的任务是开始使用可替代的可再生能源作为其供电(包括白天)。最简单的可再生能源是光伏太阳能转换器。然而,太阳能光伏发电在很大程度上取决于许多因素——地理位置、一天中的时间、大气状态、一年中的时间等等。此外,光伏发电取决于天气条件和云量,这使得它在白天不稳定,容易发生急剧变化(以一个数量级)。因此,基于可再生能源的电力系统的一个重要组成部分是发电能量的积累系统。分析了利用超级电容器对电力系统中发电量变化较大的系统进行电力稳定的方法。本文提出了具有超级电容储能装置的大功率led供电系统的设计原则,旨在提高可变电源的能源利用效率。基于超级电容的驱动系统可以确保在替代电源缺失或减少时照明系统的稳定运行,提供高安全性和可靠性,并且比基于电池的储能系统具有更长的使用寿命。

Supercapacitor energy storage systems for lighting systems with combined power supply
Modern continuous lighting systems use powerful high-performance LEDs as light sources and an important task is to begin using alternative renewable energy sources for their power supply (including during the day). The simplest of the renewable energy sources is photovoltaic solar energy converter. However, solar photovoltaic generation depends significantly on many factors - geographical location, time of day, state of the atmosphere, time of year and the like. In addition, photovoltaic generation depends on the weather conditions and cloudiness, which makes it unstable and prone to change drastically (by an order of magnitude) during daylight hours. Therefore, an important element of the power system based on renewable energy sources is the system of accumulation of generated energy. The method of power stabilization using supercapacitors for systems with a significant change in power generation in the electrical power system is analyzed. The paper offers design principles of the power supply systems for powerful LEDs with supercapacitor energy storage devices intended to make the use of energy from sources with variable generation more efficient. The systems with supercapacitor-based drives, which allow to ensure stable operation of the lighting system when the power supply from an alternative source is absent or reduced, provide high safety and reliability, and have a significantly longer service life than battery-based energy storage systems.
