（Estimation of power generation capacity）

In accordance with the annual wind velocity and direction series data and the wind turbine generator system layout plan of Buerjin Wind Farm identified by the wind resources analysis, the software—windfarmer will be used for the calculation of annual power generation in the wind farm.

（1）Estimation of theoretical annual power generation

The 66×750kW WTGSs in Buerjin Wind Farm have a theoretical annual power generation of 182,056.25MWh.

（2） Estimation of power generation capacity

Based on the theoretical annual power generation of 66 WTGSs in Buerjin Wind Farm, and with consideration to the impacts of relevant factors on the power generation of the wind farm including the availability of WTGSs, wake flow, the energy loss in the wind farm, control and the turbulence level, salt spray and blade pollution etc, the annual power generation of the wind farm is estimated as 121,275MWh, and the installed standard number of utilization hours of the wind farm is 2,450h.
