Research And Design Of A Electrical System Of A Experimental Model For Wind Power

Energy and environmental issues is the focus of attention of governments around theworld today. Sustainable development is an effective way to solve this problem. Onlywhen people insist on the implementation of the strategy of sustainable development, thedevelopment of renewable energy, in order to effectively solve these two problems ofenvironmental degradation and energy crisis. Although the wind has made gratifyingachievements, but there are still some problem and obstacle in the development can’t beproperly resolved will restrict wind power technology. In the development of wind powerpolicies and mechanisms on the issue in china, first of all, there should be a cleardevelopment goals and clear preferential incentives. Second, we must strengthen thecommercial operation mechanisms. With the rapid development of wind power technologyto stimulate a corresponding demand for talents. Through the learning of power electronicsconverter technology, skilled master the process variable flow technology in wind powergeneration. Wind turbine converter technology applications in the teaching experiment, inorder to achieve in the laboratory on small wind turbine variable flow characteristics of thestudy. According to the teaching need to build a wind power generation model, it can makethe analysis and research of the electrical control system. In the process of wind powergeneration, the electrical control system is to ensure the safety and reliability of the windturbine operation process.This article describes the research background, purpose and significance, this paperintroduces the off-grid structure and operation of each part of the wind power generationsystem principle. In this paper, an experimental model of wind power generation platformto do the overall design. By the motor as a prime mover driven generator, and thesimulation of wind power issued AC rectifier circuit and step-down circuit is converted tothe appropriate voltage to24V battery charging, and then supplied to the load through theinverter circuit use, the load is incandescent box, the load can freely switch the size of theload. In the experimental study, through the combination of software and hardware,completed the design of electrical energy transformation in the rectifier, DC circuit, batteryand inverter circuit electrical links, design calculation, including the electric parameters ofcircuit structure of hardware circuit and component selection. Operation monitoring systemsoftware design features include data acquisition and control, data analysis, data displayand so on. This research effectively solves the problem of the wind power generation processapplication in teaching experiment. To verify the relevant theoretical knowledge throughexperiment, arouse the enthusiasm of students, it can meet the requirements of windturbine operation teaching.
