風(fēng)力發(fā)電機(jī)限速與充電逆變控制器的研究
[Abstract]:Since the industrial revolution, the global energy consumption has been increasing rapidly, the mankind is facing the energy crisis, the development and utilization of renewable energy is imperative, wind energy is an important renewable energy. Wind power generation facilities can maximize the use of wind power, this paper mainly focuses on small wind power systems. At present, there are some disadvantages in the speed limit and unloading device of the small wind power system when the wind speed is too large. The wind power controller has some problems, such as lack of originality, large volume, incomplete function, weak anti-jamming ability and so on. In order to improve the small wind power generation system and solve the existing problems, this paper combines the mechanical design and manufacturing technology, power electronics technology, micro-controller technology and so on to carry on the preliminary research and design to the small scale wind power generation system. Off-grid wind power system consists of wind turbine, generator, charging controller, battery and inverter controller. In this paper, the speed limiting mechanism, charging controller and inverter controller of wind turbine in small scale wind power system are studied. In this paper, two kinds of speed limiting mechanism of wind turbine are designed, which saves the variable pitch system and the electric unloading device. The blade itself can quickly realize the speed limit function by adjusting the area of the wind surface quickly, and it is safe and reliable. In this paper, one of the speed limiting mechanisms is simulated and analyzed, and the simulation results show that the speed of wind turbine can be reduced effectively, and a charging controller is designed for 300W small wind power generation system. It can convert unstable alternating current from generator to stable 28V DC charge for 24V battery, chopping frequency is 100kHz, this can effectively reduce the volume of charging controller, it has output overcurrent, overvoltage protection, battery full charge. This paper also designs a 500VA inverter controller with capacity of 220V AC, which can be converted from 24V battery to 220V AC for user load. It adopts digital control mode, has strong anti-interference ability, and has simple topology. Inverter efficiency, high accuracy, with input overvoltage protection, output over-current protection function.
