Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of operation control of a fuel cell system, and in particular to an operation control method, device and computer-readable storage medium of a fuel cell system. Background Art
[0002] The current technical solution commonly used in the industry is that the fuel cell system receives a specific power output request from the external system, obtains the target current corresponding to the expected power of the fuel cell based on the target power, obtains the current loading rate or load reduction rate based on the current fuel cell state, and then the fuel cell system controller FCU performs fuel cell current control and operating parameter adjustment according to the response rate. The fuel cell current is the DC / DC input current, and the operating parameters are the fuel cell system pressure, flow, temperature, humidity and actuator setting value.
[0003] In order to make the fuel cell system have a better response speed, the control of the fuel cell current and operating parameters usually adopts a synchronous change control method. The main parameters that affect the performance of the fuel cell are pressure, flow, temperature, humidity, etc. Compared with the current response rate of DC / DC, the above parameters have obvious hysteresis characteristics. At the same time, it takes a certain amount of time to establish and transmit the pressure and flow inside the fuel cell. The synchronous change control method adopted by the prior art cannot solve the above problems, which will cause the actual parameters of the fuel cell system to deviate from the calibrated parameters when the load changes. This phenomenon will cause the system to have the risk of low fuel cell performance, water blockage, starvation, single low, and overtemperature during the load change process, triggering the fuel cell system to limit the output power or shut down the operation, the load change rate is slow, and the power response performance of the fuel cell system is low. Especially in high-power fuel cell systems of 200kW and above, the problem is more prominent, seriously affecting the stability of the system, and long-term continuation will accelerate the attenuation of the fuel cell life.
[0004] However, it is difficult to adjust the operating parameters in advance in the existing technology, so that the fuel cell cannot have the optimal operating state at each current point in the subsequent operation. Therefore, the fuel cell control system needs to provide a mechanism to ensure the performance and stability of the fuel cell. This limits its application effect in certain high-dynamic scenarios, leaving room for innovation and breakthroughs for the present invention. Summary of the invention
