Energy collection system

Abstract

The invention relates to an energy collection system which appropriately outputs generated electric power to a battery energy storage system (BESS) to charge while generating power by using energy collection, so as to greatly reduce operation cost and continuously and stably supply electricity for a power distribution system. Under the condition that charging of the battery energy storage system (BESS) exceeds a threshold, that is, in an excessive charging state, electric power generated by energy collection is consumed through an auxiliary lighting portion, to prevent hidden danger caused by excessive charging. Combined with and applying different energy collection methods, originally limited elements are compensated through other different energy collection methods when each energy collection system is applied. Thus, continuous and stable electric power supply is realized, and blades can easily rotate even though in weak wind speed environment, promoting obvious improvement of electric power efficiency.

Description

technical field [0001] The present invention relates to an energy harvesting system. Specifically, energy harvesting is used to provide stable and continuous power supply to the lighting part of the power distribution system, while greatly reducing operating costs, improving power efficiency, and preventing hidden dangers caused by overcharging in advance. . Background technique [0002] Energy Harvesting (Energy Harvesting) is a technology that collects waste energy from the surrounding area and then converts the energy into electrical energy. Because it can reduce the emission of harmful substances during the energy acquisition stage, it has attracted much attention in the field of environmentally friendly energy. [0003] figure 1 It is a block diagram showing a power supply system described in Korean Registered Patent No. 10-1201522 (Title: Hybrid uninterruptible power supply system using battery fuel and its control method).

Problems solved by technology

[0006] However, since the conventional technology (100) simply adds a fuel cell, not only cannot use other energy sources such as solar energy and wind power, but also has problems of low energy efficiency and high maintenance costs.

[0007] In addition, the conventional technology (100) has a structural limitation in that the second battery unit (130) continues to be charged regardless of whether it is in an overcharged state, resulting in overcharging so that hazards occur

[0008] In addition, in the traditional technology (100), the power generated by the fuel cell unit (120) depends on the environment such as weather and climate. When the environment is at a disadvantage, the stored power delivered to the second battery unit (130) is insufficient. It will cause the problem that the power cannot be continuously and stably supplied. Such an unstable power supply will cause the failure of the electronic equipment of the power distribution system.
