| Energy is an important guarantee for a country or region’s economic development, social stability and people’s living level. With Energy supplies becoming strained, wind energy is attached the whole world and becomes the fastest developing renewable energy, because its natural resources is rich, it is friendly to environment, and the costs is gradually reduced. China has abundant wind energy resources. The wind energy is better and richer in many rural and remote areas. Thanks to matures of wind power technique, wind power will be an important way to solve the problem of remote site electric power supply.This paper studies on the influence of wind power on the power supply of remote site, which has both the Theoretical significance and great practical significance. Firstly, the domestic and overseas situation and hot issues of wind power at present are analyzed, so is remote area power supply. It is concluded that the study has a favorable picture and the research is useful and theoretical. Secondly, wind generator work principle and structure characteristics are introduced. The operation modes and characteristics are compared and discussed. Wind generator fault diagnosis is analyzed. Thirdly, based on Double-fed Inductive Wind Generators, A systematic approach to modeling the dynamic characteristics of wind generator is presented, as well as the control method. Due to the remote area power supply, the suitable generator and operator mode to remote area power supply are researched on. The conclusion is that Double-fed Inductive Wind Generators and grid connected mode are better way to remote area so as to get sufficient and qualified electric power. Then, take a wind farm as an example, the configuration, connection and control mode is introduced. The wind farm plays an important role to solve electric power shortage in remote area. Finally the wind power generation in remote site development prospect and power supply system facing technical problems are analyzed and summed up. |
