Simulation Analysis Of High Temperature Superconducting Generator For Wind Power Generation Based On ANSYS

In recent years, the global economy continues to develop in general, the size of the population is also growing, leading to the increasement of human demand for energy every year.The continuous development of energy resources makes the world's total energy in a declining state.Besides, the burning and usage of fossil energy brought a series of environmental problems along with the condition.The environment and ecological balance are at the deteriorating situation which gradually attracts the attention of the world.As a result,the human pursuit and development of new energy sources is increasingly urgent.Wind energy can be developed as a large, widely distributed, clean and non-polluting, renewable energy sources,and has attracted more and more human attention. It is also the current renewable energy in human development techniques and is playing an increasingly important role in the economy and society.Meanwhile, continuing to improve the efficiency of the generator is also an effective way to improve the efficiency of the usage of energy.There are two kinds of the current operational wind power systems. First, the high-speed wind power generation system; the second is the direct-drive wind power generation system.But because of the body of the generator body is quite large, increasing the difficulty of transportation and installation, mechanical efficiency can not meet the requirements of humanity,too.In recent years, science technology has made great progress. Research of high-temperature superconducting materials has made considerable progress. HTS motors come into being as a result. Compared with the currently used motor, HTS motor has obvious advantages, such as low synchronous reactance, small size, light weight and high efficiency. Therefore, HTS generator has incomparable advantages over universal generators in the power-saving and resource conservation, and will have high development prospects in the future development and application.For these reasons,the paper focuses on the basics of the structure of the generator.The general excitation motor is compared. We adopt ANSYS software to build the two-dimensional model and finite element analysis and introduce the relevant knowledge of high-temperature superconductors.We resolve the electromagnetic field distribution of the motor.Combined with relevant experimental data, we calculated the motor load EMF on the basis of the two-dimensional modeling, and eventually got a two-dimensional state of flux density HTS generator.The variables relationship of current, voltage, speed are simulated at different loads on the basis of ANSYS software simulation.The data are compared and analyzed with general motors, combined with the comparison and analysis of the experimental data, and we ultimatelyget a more intuitive understanding of the advantages of HTS generator of wind power.It provides an effective source of data for the design of HTS motor.
