DETAILED DESCRIPTION

[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] Wind power generation has the characteristics of intermittency and volatility. In the off-grid operation mode, how to stably and efficiently convert wind energy into hydrogen energy becomes a key problem in research and application. In the related art, there is a lack of complete testing means for the overall performance of the system under off-grid conditions, which cannot simulate the real wind power generation environment, resulting in difficulty in accurately and comprehensively testing the wind power hydrogen production system.

[0025] Based on this, the test device for wind power hydrogen production provided in the embodiments of the present application can be applied to the simulation, research and development, and testing of wind power hydrogen production.

[0026] As shown in Figure 1 The test device for wind power hydrogen production disclosed in the embodiments of the present application includes: a wind power simulation device 10, a hydrogen production load simulation device 11, and a test monitoring device 12; the wind power simulation device 10 and the hydrogen production load simulation device 11 are connected; the test monitoring device 12 is connected with the wind power simulation device 10 and the hydrogen production load simulation device 11 respectively.

[0027] The wind power simulation device 10 is used to provide electric energy to the hydrogen production load simulation device; the wind power simulation device can obtain electric energy from the power grid or other energy storage devices. In order to simulate the intermittency and volatility of wind power generation, the wind power simulation device has a programmable function. The wind power simulation device includes a voltage converter, a current converter, a controller, etc.

[0028] In one way, a software model or device characteristic parameter of a wind turbine generator set can be run in the wind power generation simulation device to simulate the output characteristics of the wind turbine generator set, including fan speed, rotational inertia, wind speed, variable pitch control, load, etc. After the wind speed curve and other environmental parameters are input into the wind power generation simulation device, the wind power generation simulation device calculates the voltage control parameter based on the wind speed curve, environmental parameters, and in reference to the software model or device characteristic parameter of the wind turbine generator set; the wind power generation simulation device controls the power parameters output by the wind power generation simulation device, such as voltage, frequency, current, etc. through the voltage control parameter. Since the wind speed curve simulates the change of wind speed and the environmental parameters simulate the wind power generation environment, the voltage control parameter obtained through the wind speed curve and the environmental parameters also changes with the change of wind power, thereby simulating the intermittent and fluctuating characteristics of wind power generation. The environmental parameters can include temperature, weather, wave height, etc.

[0029] In another way, a power curve and environmental parameters are input into the wind power generation simulation device, the power curve simulates the change of power generated by the fan when the wind speed changes; the wind power generation simulation device controls the power parameters output by the wind power generation simulation device according to the power curve and the environmental parameters, which can also simulate the intermittent and fluctuating characteristics of wind power generation.

[0030] When the hydrogen production load simulation device is running, the wind power generation simulation device can adjust the operating state of the wind turbine generator set according to the rotational inertia of the wind turbine generator set, the energy consumption of the hydrogen production load simulation device, etc.

[0034] In the above manner, the wind power generation simulation device simulates the real wind power generation environment in an off-grid operation mode, the hydrogen production load simulation device simulates the electric energy consumption of real hydrogen production equipment, and the test monitoring device interacts with the wind power generation simulation device and the hydrogen production load simulation device to achieve accurate and comprehensive testing of the wind power hydrogen production system.

[0035] In an implementation manner, the wind power generation simulation device includes an AC / AC converter and a first controller; the AC / AC converter and the first controller are connected; the first controller is used to provide an electric energy control parameter to the AC / AC converter; and the AC / AC converter is used to convert first alternating current electric energy input into the AC / AC converter into second alternating current electric energy according to the electric energy control parameter and output the second alternating current electric energy.

[0036] The first alternating current electric energy can be input into the AC / AC converter from a power grid, a power source, or an energy storage device; and the AC / AC converter converts the first alternating current electric energy into the second alternating current electric energy and outputs the second alternating current electric energy under the control of the electric energy control parameter. The electric energy control parameter can include a voltage control parameter, a current control parameter, a frequency control parameter, and the like. The first controller can send the electric energy control parameter to the AC / AC converter through a communication mode in the related art; and the AC / AC converter can process the electric energy control parameter through a parameter processing mode in the related art, so as to realize electric energy conversion.

[0037] In order to simulate the intermittence and volatility of wind power generation, the first controller can output different electric energy control parameters at different time points, so that the second alternating current electric energy output by the AC / AC converter also changes constantly and presents the characteristics of intermittence and volatility.

[0038] For example, the wind power generation simulation device can simulate the wind power generation environment in the off-grid operation mode, and the hydrogen production load simulation device can simulate the electric energy consumption of the real hydrogen production equipment.
