| Because the investment of wind power generation equipment occupies a large proportion of construction investment in the whole wind farm and choosing the reasonable wind turbine is directly related to the future operation of the production, selection of wind turbine is one of the major tasks in the wind farm design. The selection of wind turbine is the results of a number of factors and overall optimization of multi-index. Therefore, taking fully into account the objective conditions, such as the local topographic features and climate characteristics, when we analyze the economic index of the wind turbine, we must take fully into account the elements of investment projects during the operational changes and the time value of money, in order to get the maximum benefits in a limited period of time when we analyze the economic index of the wind turbine. In this paper we lead into the Wellbul wind speed distribution function. Combine dynamic economic index with static economic index. And firstly put forward the wind turbine matrix layout about the construction of large-scale wind farms in China, in order to avoid the "spider web" effect and reduce the project cost, covering, and transmission loss, better put into operation after the operation and maintenance and achieve wind turbine of "multi-machine a change". In this paper, we make a large-scale and under construction wind farm for a specific case to carry out the optimization of wind turbine selection and layout studies. |
