Offshore hydropower station hoisting mechanical system based on hydrogen fuel cell

Abstract

An offshore hydropower station hoisting mechanical system based on a hydrogen fuel cell is characterized in that a hydrogen fuel cell system is adopted to supply power to a hydropower station hoistingmachine, and the hydrogen fuel cell system is arranged beside driving motor equipment of the hydropower station hoisting machine; after the hydrogen fuel cell system is started, working signals are transmitted to an energy management module, the energy management module controls the hydrogen fuel cell system to supply power to a motor controller after receiving load signals transmitted by the hydrogen fuel cell system and the motor controller, and the motor controller drives a motor to act. The hydrogen fuel cell system is simple in power supply mode, clean, green, free of pollution and goodin economy, the hydrogen fuel cell system has the characteristics of being high in energy storage density and large in output power, and reliable and convenient power supply of the hydropower stationhoisting mechanical system is achieved; the hydrogen fuel cell system is arranged beside the driving motor equipment of the hydropower station hoisting machine, as a result, a large number of cables do not need to be laid, plant space is not occupied, and attractiveness is good.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydroelectric power technology, and more specifically relates to a hoisting machinery system for offshore hydroelectric power stations based on hydrogen fuel cells. Background technique [0002] A large number of various types of hoisting machinery are equipped in the hydropower station, such as bridge cranes, portal cranes, and hoists, which are used for lifting and operating heavy equipment and facilities. Taking a giant hydropower station as an example, two 1300t / 160t main bridge cranes and one 160t+160t electric double-girder double-trolley bridge crane are installed on the roof of the factory building, which are used for hoisting the rotor of the hydro-generator in the hydropower station. The rotor hoisting of hydro-generator has the following characteristics: [0003] (1) The electricity load is large. The maximum operating current of the 1300t bridge machine is 1860A, the peak current...

AI Technical Summary

Problems solved by technology

[0006] (4) High power supply reliability requirements

[0011] (2) General power supply reliability

Although dual-circuit power supply and other related measures to ensure power supply reliability have been adopted, there are many devices in the entire power supply circuit, and the protection setting is complicated, which may cause accidental interruption of power supply

[0012] (3) Large amount of cable laying, poor aesthetics

Bridge machine power supply cables are generally very thick, with a large turning radius, and are directly laid on the wall of the main factory building, which is difficult to handle locally and easily affects the decoration effect of the main factory building

Moreover, when the cables extend out of the main factory building and connect to the trolley line, because the cable radius is too thick, it is often very difficult to connect for large-capacity bridge machines, and there are many restrictions

Leading to repeated adjustments in the on-site installation plan
