Problems solved by technology
[0004] In view of this, the embodiment of the present invention provides a method and device for controlling the electric heat output of the hydrogen comprehensive utilization system to solve the problem that the electric heat output of the hydrogen comprehensive utilization system cannot be flexibly changed in the prior art, which easily leads to unreasonable resource allocation. question
Through the above steps, the actual output electric energy of the fuel cell system is adjusted, so that the actual output electric energy of the fuel cell system changes with the needs of users, and the flexibility is good, which solves the problem that the output electric heat of the hydrogen comprehensive utilization system in the prior art is not flexible. Changes can easily cause unreasonable resource allocation problems

The invention provides a method and device for controlling the electric heat output of a hydrogen comprehensive utilization system. The hydrogen comprehensive utilization system includes a fuel cell system and a heating circuit. The heating circuit is installed in the cooling circuit of the fuel cell system. According to the demand for electric energy, Calculate the required intake flow of the fuel cell, adjust the hydrogen intake through the mass flow regulator of the hydrogen circuit, adjust the intake flow of the air circuit by controlling the speed of the air compressor or blower or the mass flow regulator, and output the current according to the demand Adjust the speed of the water pump or the water proportional valve, control the flow of cooling water, and then control the temperature difference between the inlet and outlet of the fuel cell, and adjust the inlet water temperature by controlling other cooling equipment such as radiators or chillers to ensure the water and heat balance inside the fuel cell. The flow of the hot water supply circuit is used to meet the heat demand and change the electric heat output. By implementing the invention, the actual output electric heat of the fuel cell system can be changed according to the needs of users, and the flexibility is good.
Description
technical field [0001] The invention relates to the technical field of hydrogen energy utilization, in particular to a method and device for controlling electric heat output of a hydrogen comprehensive utilization system. Background technique [0002] At present, with the acceleration of my country's urbanization process, commercial buildings such as shopping malls, supermarkets, hospitals, office buildings, hotels, and some residential users have gradually become the main energy consumers in cities. However, most of the current buildings use electricity and heat in a centralized supply, that is, It often relies on air-conditioning and other electric heating / cooling methods, resulting in a large amount of energy loss and low energy utilization rate. Moreover, the uniform heat supply time of this method is one of the important factors causing the problem of "load peak-valley difference". Affect the economic operation of the grid. [0003] In response to the above situation, hy...
