Abstract
The invention discloses an extensible fuel cell emergency power generation system, which comprises a plurality of fuel cell power generation modules, a hydrogen supply system, an inverter, a system controller and an electrical interface, wherein an input end of the parallel fuel cell power generation modules is connected with the hydrogen supply system, and an output end of the parallel fuel cell power generation modules is output to a DC/AC (Direct Current/Alternating Current) inverter and then to the electrical interface through a power distribution box; and a system controller is connected with each power generation module, the hydrogen supply system and the DC/AC inverter in a wireless communication mode. Each set of fuel cell power generation module is an independent power generation unit, the normal work of other power generation module units is not affected when a set of fuel cell power generation module fails in the emergency power generation system; when the external demand power is small, the fuel cell does not operate at the optimal working state, so that the service life of the fuel cell is not affected; and the system has a simpler structure and is lower in efficiency.

As further feature of the present invention, described wireless communication mode is a CAN bus communication mode.
As further feature of the present invention, described fuel cell power generation module has independently auxiliary system, hydrogen supply pipeline, DC/DC DC converter and module controller.
Owing to adopt above technical scheme, a kind of extendible fuel cell emergency generation system of the present invention, every suit fuel cell power generation module all is a generator unit independently, has the cover fuel cell power generation module Shi Buhui that breaks down to influence the operate as normal of other electricity generation module unit in emergency generation system; When external demand power hour, fuel cell does not operate in optimum Working, can not impact its useful life, and system architecture is comparatively simple, system effectiveness is lower.
Description of drawings
The invention will be further described with specific embodiment with reference to the accompanying drawings below:
Fig. 1 is an expandable type fuel cell emergency generation system Organization Chart;
Fig. 2 is fuel cell generation controller topological structure figure.
Embodiment
As Fig. 1, shown in 2, a kind of extendible fuel cell emergency generation system, comprise several fuel cell power generation modules 4, hydrogen-feeding system 2, DC/AC inverter 3, auxiliary energy storage module 6, touch-screen 5, system controller 1 and use electrical interface, input after several fuel cell power generation module 4 parallel connections is connected with hydrogen-feeding system 2, output outputs to DC/AC inverter 3 backs and passes through a distribution box to using electrical interface, system controller 1 and each fuel cell power generation module 4, hydrogen-feeding system 2, touch-screen 5, carry out CAN bus communication mode between the DC/AC inverter 3, fuel cell power generation module 4 has independently auxiliary system, the hydrogen supply pipeline, DC/DC DC converter and module controller; Also comprise an auxiliary energy storage module 6, it is connected between the output and DC/AC inverter 3 of several in parallel fuel cell power generation modules 4, and auxiliary energy storage module 6 mainly provides the fuel cell start-up energy and externally provides support and cushioning effect under the situation of load changing.
After emergency generation system powers on, system controller 1 detects each fuel cell power generation module 4 states, hydrogen-feeding system 2 states and inverter 3 operating states, start each fuel cell power generation module then successively, enter idling mode, if there is individual fuel cell electricity generation module state undesired, then select not start.
The user can be by being that power consumption equipment is powered with electrical interface, system controller 1 is adjusted the output of each fuel cell power generation module 4 according to output voltage and electric current, suitably reduce its power output when a certain module performance is not good, the module of better performances is many outputs power then; When a certain module breaks down then with its shutdown.
Less when external loading, then stop 4 work of part of fuel cell power generation module; When external loading increases, then start corresponding fuel cell power generation module 4 work.
System mode can show by touch-screen 5.
After system detects halt instruction; the fuel cell power generation module 4 that 1 pair of system controller is moving is sent halt instruction; and order hydrogen-feeding system 2 is closed hydrogen; stop inverter 3 outputs; treat that all modules, hydrogen-feeding system, inverter are all shut down and cut off general supply more voluntarily after finishing, realize system-down.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
