Embodiment 1

[0030] Wind turbine simulation experiment system based on adaptive control algorithm, as shown in the attached figure 1 As shown, it includes a data acquisition terminal, an adaptive control module and a drive module. The data acquisition terminal is used to obtain the given speed of the wind rotor, and collect wind force information, the actual speed of the wind rotor and the actual pitch angle of the blades. The given speed of the wind rotor is set by the staff according to the required constant power. The wind force information includes wind speed and wind direction. The actual speed of the wheel is the rotation speed of the wind wheel under the action of wind force, and the actual pitch angle is the pitch angle of the current blade.

[0031] The adaptive control module is used to generate blade control information according to the given speed of the wind rotor and wind force information; it is also used to generate the speed deviation according to the actual speed of the w...

Embodiment 2

[0039] The differences between this embodiment and Embodiment 1 are:

[0040] The data collection terminal is also used to collect the actual power of power generation, which is the actual power output by the wind power generating set. The self-adaptive control module is also used to generate a given power for power generation according to the actual rotational speed of the wind rotor, generate a power error based on the given power for power generation and the actual power generated for power generation, and generate power control information based on the power error and the actual power generated for power generation. The driving module generates power driving information for controlling the converter according to the power control information.

[0041] The data collection terminal also includes a power sensor, which is used to collect the output power of the wind power generating set as the actual power generated.

[0042] The controller is also used to control the convert...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that this program is applied to the simulation experiment teaching for students. Since the number of students in each teaching is large, and the cost of the simulation experiment teaching equipment is not low, the simulation experiment teaching equipment The numbers clearly do not match the number of students. In order to realize the simulation experiment teaching of students, the existing simulation experiment usually adopts two methods, one is to divide the students into groups and conduct the simulation experiment with the group as a unit, and the other is to divide the students into batches to carry out the simulation experiment, using the former method It is impossible to evaluate the simulated experiment situation of each student. Using the latter method requires relatively large time and teaching costs, which affects the teaching progress of teachers and the learning progress of students. Therefore, adopt...

Abstract

The invention relates to the technical field of education or demonstration tools, and especially relates to a wind generating set simulation experiment system based on a self-adaptive control algorithm. The system comprises a data acquisition terminal, a self-adaptive control module and a driving module, and the data acquisition terminal is used for acquiring a given rotating speed of a wind wheeland acquiring wind power information; the self-adaptive control module is used for generating paddle control information according to the given rotating speed of the wind wheel and the wind power information; the driving module is used for generating paddle driving information for controlling the paddle according to the paddle control information; the data acquisition terminal is also used for acquiring the actual rotating speed of the wind wheel and the actual pitch angles of the blades; and the self-adaptive control module is further used for generating rotating speed deviation according tothe actual rotating speed of the wind wheel and the given rotating speed of the wind wheel and updating the blade control information according to the rotating speed deviation and the actual pitch angle. By adopting the scheme, the technical problems that the control precision is reduced and the output power of the wind generating set cannot be kept constant due to low adaptive capacity of a variable pitch control system in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of education or demonstration appliances, in particular to a simulation experiment system of a wind power generating set based on an adaptive control algorithm. Background technique [0002] As a strategic emerging industry, wind power has been highly valued by the country and region, and has become the focus of renewable energy development. At the same time, actively developing wind energy has far-reaching significance for improving the structure of the energy system, alleviating the energy crisis, and protecting the ecological environment. Therefore, the cultivation of wind power technology talents is particularly critical. However, due to the fact that the existing wind turbines are generally over 40 meters in height, larger in size, and require a larger site, they do not use the laboratory to carry out teaching and training, which hinders the existing talent cultivation. [0003] In order to strengthen ...
