Introduction  Basically， the centralized wind power projects in South China or on land have been developed， and the distributed wind power projects based on making full use of the idle land around villages and towns or factory areas have sprung up. It is expected that the distributed wind power generation which utilizes low-speed wind will bring new incremental space for the domestic wind power market. Whether the location of distributed wind turbine is right or not will directly affect the economic benefit of the power station. Due to the fact that there is no support of wind resource data actually measured on the idle land around villages and towns or factory areas， it is facing a great challenge to develop distributed wind farms or select the site and type of the wind turbine.

  Method  This paper put forward the idea of finding the load first， then selecting the site of wind power plant， and to analyze and select the best wind turbine location depending on the meteorological data of wind resources.

  Result  The research shows that： taking the design of a distributed wind farm in South China as an example， by adopting the idea of distributed-wind-power plant site selection and wind turbine type selection proposed in this paper， making full use of the idle land around the factory and mine， the optimal design suggestion of selecting to use three sets of 3X anti typhoon type wind turbines with 100-meter-high hub is reached.

  Conclusion  The proposed idea of distributed wind power plant location and wind turbine type selection is correct and effective， which can provide guidance for practical operation.
