The thesis clarifies the design of the small independent wind power generation system in detail and makes a deep research about the structure of the wind turbine system, power transformation and the relay control circuit. In view of the author, the solution is: wind turbine generators drive three-phase AC electric generator, then the power is transformed into standard AC power through the AC-DC-AC system. And considering instability of the wind, we must install batteries in this system so that we can ensure normal power supply. The operation of the system is monitored and switched by the relay control circuit. The paper focus on the control circuit part. And make a specific analysis about the operation of the system in all different conditions. In the end, the paper made simulation to support the theories. Keyword Wind Turbine System; AC-DC-AC;Relay Control Circuit. 目录  TOC \o 1-3 \h \z \u  TOC \o 1-3 \f \h \z \u   HYPERLINK \l _Toc261706901 摘要  PAGEREF _Toc261706901 \h i  HYPERLINK \l _Toc261706903 Abstract  PAGEREF _Toc261706903 \h ii  HYPERLINK \l _Toc261706905 第一章 绪论 1  HYPERLINK \l _Toc261706906 1.1 风力发电概述 1  HYPERLINK \l _Toc261706907 1.1.1 风力发电现状与展望 1  HYPERLINK \l _Toc261706908 1.1.2 风力发电的原理和特点 2  HYPERLINK \l _Toc261706909 1.2 论文系统概述 3  H
