Review on Met Mast Site Selection Methods in Grid-Connected Wind Farm

Met mast is one of the most important devices to assessing wind resource, calculating wind energy production and predicting wind power in the grid-connected wind farm. Met mast site selection is a key problem for the representativeness. Met mast site selection in the grid-connected wind farm was discussed in this paper. First, this paper analyzed the differences of establishing conditions between the met mast in the grid-connected wind farm and in the wind farm being designed. The best site to build a met mast may change because of the change of the flow field in the wind farm. Second, the principles of met mast site selection are summarized. Wake impact which causing the changes of flow field should be considered in the site selection of a met mast. Last, suggestion and research direction about the met mast site selection in grid-connected wind farm are proposed.
