Passive power supply method and power supply system for vanadium cell emergency power supply

Abstract

The invention relates to a passive power supply method and a power supply system for a vanadium cell emergency power supply. According to the passive power supply method and the power supply system for the vanadium cell emergency power supply, by the aid of the height position difference between a vanadium solution and an electric pile, the vanadium solution is enabled to flow into the electric pipe due to the gravity effect to achieve electricity generation. The passive power supply system for the vanadium cell emergency power supply comprises a vanadium solution supply end and the electric pile, wherein the vanadium solution supply end is located above the electric pile. According to the passive power supply method and the power supply system for the vanadium cell emergency power supply, the technical problems in prior art are effectively solved, any additional device is not required for assisting power supply, and only by means of the height position difference between the vanadium solution and the electric pile, the vanadium solution flows into the electric pile due to the gravity effect to achieve the electricity generation, so that other power consumption devices are driven to work, and the stability and the safe reliability of main and standby power source stations are effectively guaranteed.

Description

【Technical field】 [0001] The invention relates to a vanadium battery power supply method and a power supply system, in particular to a passive vanadium battery security power supply method and a power supply system. 【Background technique】 [0002] In the prior art, in order to ensure the stable operation of the main and backup power stations, a backup power system is often set up. The purpose is to meet the power demand of the load through the normal power supply of the backup power system when the main and backup power stations cannot work normally. Ensure the stability of the main and backup power stations. This puts forward higher requirements on the stability of the backup power system (security power supply system). [0003] During the 4.11 earthquake in Japan, the Fukushima nuclear power plant (the main and backup power plant) was devastated and could not work normally. The heavy-duty motors and other protective devices in its backup power system were also unable to r...

AI Technical Summary

Problems solved by technology

[0003] During the 4.11 earthquake in Japan, the Fukushima nuclear power plant (the main and backup power plant) was devastated and could not work normally. The heavy-duty motors and other protective devices in its backup power system were also unable to receive normal power supply due to the destruction of the power system and lost their work. performance, the nuclear reactor could not be cooled, which eventually led to the explosion of the nuclear power plant unit, resulting in the leakage of radioactive materials and causing huge losses

[0004] The reason for the above losses is not that the main and backup power stations are not equipped with a backup power system (security power supply system), but that the backup power system (security power supply system) in the prior art requires the effective support of electric power to work normally. Therefore, how to ensure that the backup power supply system (security power supply system) can also provide normal power supply in harsh environments has always been a major problem for those skilled in the art.
