Embodiment 1

[0048] This embodiment aims at the problem that the current hydrogen production system adopts personnel independent monitoring, which cannot realize pure unattended and fault warning, and provides a hydrogen production system based on AEL and PEM water electrolysis technology. The sensing signal module obtains the operation data (working information, environmental information) of the compound tank hydrogen production equipment, and transmits the operation data to the control module for data processing, accident prediction and situation correction, so as to ensure the stable operation of the hydrogen production system and realize unattended and Fault warning function.

[0049] For details, please refer to figure 1 , the hydrogen production system based on AEL and PEM water electrolysis technology includes: composite tank hydrogen production equipment 1, power supply device 2, control device (situation awareness signal module 3, control module 4 and cloud server 5), the control ...

Embodiment 2

[0065] This embodiment provides a situation control method for a hydrogen production system, which is applied to a hydrogen production system based on AEL and PEM water electrolysis. The situation control method includes the following steps:

[0066]Collect data from the signal acquired by the situational awareness signal module, import the collected data into the big data information database for big data analysis, and evaluate the weight of different situational signal objects through the entropy weight method;

[0067] Construct an accident entropy model to monitor the accident entropy to predict the probability of occurrence of the corresponding risk of the accident situation, carry out the accident situation model fitting on the relevant risk factors, and then obtain the corresponding maximum risk influencing factor, and perform prediction and alarm on this factor and its related risk factors ;

[0068] Steady-state control is carried out through the control module corres...

Abstract

The invention discloses a hydrogen production system based on AEL and PEM water electrolysis and a situation control method. According to the hydrogen production system, an AEL water electrolysis tank and a PEM water electrolysis tank are matched with each other and highly integrated in a water electrolysis hydrogen production system, and anaccident early warning monitoring method based on situation awareness is provided in consideration of a related complex management and control system, and is different from the lacking of situation awareness early warning function for detection information in an existing water electrolysis hydrogen production system. According to the invention, an optimal working mode of a hydrogen production system is evaluated based on accident entropy, the situation awareness object category is predicted after the situation awareness information is acquired, and then the increment change of the working mode of the situation awareness object to the accident entropy of the system is evaluated so as to provide the increment direction of the accident situation for accident early warning, so that the system can autonomously obtain a control decision through situation awareness information analysis, adjustment is carried out through different pieces of situation awareness information, and optimal working situation optimization of the system is achieved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production, and in particular relates to a hydrogen production system and a situation control method based on AEL and PEM water electrolysis. Background technique [0002] Hydrogen is a clean and environmentally friendly secondary energy source. At present, the main hydrogen production processes include: water electrolysis hydrogen production, photo / thermal catalytic hydrogen production, fossil fuel hydrogen production and biological hydrogen production. Among them, hydrogen production by water electrolysis can be used to absorb waste electricity generated by renewable energy such as photovoltaics and wind power, and convert electric energy into hydrogen energy. It has the characteristics of high hydrogen purity, pollution-free production process, and flexible and adjustable hydrogen production scale. [0003] At this stage, electrolytic water hydrogen production technology has become the main te...
