All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application is described in further detail below with reference to the accompanying drawings.

In order to solve the above problem, embodiments of the present application disclose a hydrogen fuel cell power generation optimization system. Referring to fig. 1, a hydrogen fuel cell power generation optimization system includes a power plant 1, a multifunction meter 2, a controller 3, a hydrogen fuel cell 4, and a storage battery 5; the multifunctional meter 2 is used for detecting real-time load power of the power equipment 1 and then sending the power to the controller 3, a comparison module 31 is arranged in the controller 3, the power is compared with preset power through the comparison module 31, and a corresponding signal is output; then, the hydrogen fuel cell 4 and the storage battery 5 are selected to work according to the signal, and by the mode, the hydrogen fuel cell 4 can be ensured to be always in the optimal power range, the performance of the hydrogen fuel cell 4 is convenient to optimize, and the use efficiency of the hydrogen fuel cell 4 is improved.
Specifically, the multifunctional meter 2 is connected with the power equipment 1 and is used for collecting the load power of the power equipment 1 and outputting a real-time power signal; the controller 3 is connected with the multifunctional meter 2, a comparison module 31 is arranged in the controller 3, and the comparison module 31 receives the real-time power signal sent by the multifunctional meter 2 and compares the real-time power signal value with a preset optimal power range value; the optimal power range value includes an optimal power maximum value and an optimal power minimum value, and the comparison module 31 compares the real-time power signal value with the optimal power maximum value and the optimal power minimum value, respectively.
When the real-time power signal value is not greater than the optimal power minimum value, the controller 3 outputs a selection signal, the controller 3 sends the selection signal to the storage battery 5, and the storage battery 5 receives the selection signal and starts to work; at this time, the load power of the power plant 1 is small, and it is not suitable for the power supply using the hydrogen fuel cell 4, and it is only necessary to supply power by the battery 5.
When the real-time power signal value is larger than the minimum value of the optimal power and not larger than the maximum value of the optimal power, the controller 3 outputs a selection signal and sends the selection signal to the hydrogen fuel cell 4, and the hydrogen fuel cell 4 receives the selection signal and starts to work; at this time, the load power of the power plant 1 is within the optimum power range of the hydrogen fuel cell 4, and only the power supply by the hydrogen fuel cell 4 is required.
When the real-time power signal value is larger than the maximum value of the optimal power, the controller 3 outputs a selection signal and sends the selection signal to the storage battery 5 and the hydrogen fuel cell 4, and the storage battery 5 and the hydrogen fuel cell 4 receive the selection signal and start to work simultaneously; at this time, it is explained that the load of the power plant 1 requires the battery 5 to operate together with the hydrogen fuel cell 4 to supply power, and at this time, the output power of the hydrogen fuel cell 4 is kept at the optimum power maximum value within the optimum output power range, and the rest is output from the battery 5.
A power threshold is also set in the controller 3, and when the real-time power signal value is greater than the maximum optimal power value, the implicit condition is that the real-time power signal value is less than the power threshold, and the power threshold is greater than the maximum optimal power value; when the real-time power signal value is larger than the power threshold value, the controller 3 outputs a charging signal, the hydrogen fuel cell 4 receives the charging signal, and all the hydrogen fuel cells 4 are used for charging the storage battery 5 with load, so that the storage battery 5 can realize impact in a short time, and can perform supplementary charging under the condition of short-time overload, and at the moment, the storage battery 5 can be charged through the hydrogen fuel cell 4, so that the storage battery 5 can meet the requirement of short-time supplementary charging.
A stop threshold value is also arranged in the controller 3, and the stop threshold value indicates that when the hydrogen fuel cell 4 and the storage battery 5 output at the maximum power simultaneously, the requirement of the power equipment 1 still cannot be met, and then when the real-time power signal value is not less than the stop threshold value, the controller 3 outputs a stop signal; the system in the embodiment of the application further comprises a DC/AC inverter controller 7 and a DC/DC converter 6, the DC/DC converter 6 is connected with the hydrogen fuel cell 4 and the storage battery 5, the DC/AC inverter controller 7 is connected with the DC/DC converter 6, the DC/AC inverter controller 7 is also connected with the power equipment 1, and after the DC/AC inverter controller 7 receives a stop signal, the DC/AC inverter controller 7 stops outputting electric energy to the power equipment 1, so that the effects of protecting the hydrogen fuel cell 4 and preventing the storage battery 5 from over-discharging are achieved.
The hydrogen fuel cell monitoring system further comprises an alarm 9, wherein the alarm 9 is connected with the controller 3, receives the stop signal and gives an alarm to remind relevant workers that the hydrogen fuel cell 4 and the storage battery 5 stop working and need to perform corresponding inspection; the alarm 9 is an audible and visual alarm.
The hydrogen fuel cell system further comprises two temperature sensors 8, wherein one temperature sensor 8 is connected with the hydrogen fuel cell 4 and used for detecting the temperature of the hydrogen fuel cell 4 and outputting a first temperature detection signal; the other temperature sensor 8 is connected with the storage battery 5 and used for detecting the temperature of the storage battery 5 and outputting a second temperature detection signal; the two temperature sensors 8 are connected with the controller 3 and send a first temperature detection signal and a second temperature detection signal to the controller 3, the comparison module 31 in the controller 3 compares the first temperature detection signal value and the second temperature detection signal value with a preset temperature threshold value, whether the temperatures of the hydrogen fuel cell 4 and the storage battery 5 are too high is judged in such a way, and if the first temperature detection signal value or the second temperature detection signal value is larger than the preset temperature threshold value, the controller 3 outputs an alarm signal; the alarm 9 receives the alarm signal and gives an alarm in response to the alarm signal to remind a worker that a current system has a fault and corresponding measures should be taken.
In addition to the above-mentioned several situations, a special situation may also occur during the above-mentioned work; under the special condition, the output power of the power equipment 1 fluctuates, and the fluctuation can cause certain influence on the hydrogen fuel cell 4 and the storage battery 5, so when the output power of the power equipment 1 fluctuates, the hydrogen fuel cell 4 and the storage battery 5 should be stopped to work, and alarm reminding is performed; specifically, a timing module 32 and a storage module 33 are further disposed in the controller 3, the timing module 32 is used for timing, and the storage module 33 is used for receiving and storing the real-time power signal.
When the controller 3 receives the real-time power signal, the real-time power signal value is stored in the storage module 33, and at this time, the timing module 32 starts timing and outputs a timing signal; the comparing module 31 is connected to the timing module 32, receives the timing signal, compares the value of the timing signal with a preset time threshold, and stores the value of the real-time power signal received at this time in the storage module 33 when the value of the timing signal is equal to the time threshold; the comparison module 31 is connected with the storage module 33, performs difference calculation on the two real-time power signal values stored in the storage module 33 to obtain a power difference value, then compares the power difference value with a preset difference value, and if the power difference value is not less than the preset difference value, the controller 3 outputs an alarm signal; the alarm 9 receives the alarm signal and works; it can be understood that, after the controller 3 receives the real-time power signal, the whole signal value is stored, timing is started, after a preset time, the real-time power signal value is recorded again, the two signal values are compared, whether the difference value of the two signals is larger than the preset difference value is judged, if so, the fluctuation of the real-time power signal is larger in the preset time, and then, in consideration of protecting the hydrogen fuel cell 4, an alarm needs to be given to remind a worker.
