Wind Turbines and Data Analysis

What data have you collected? If it is wind speed and duration, then a simple Microsoft Excel spreadsheet graph of this including figures for average wind speed and wind utilisation (additional upper and lower wind speed limit lines to clearly show the minimum and maximum range of wind speed the turbine will produce power within) is a good start. Also, an additional calculated power generated graph (based on wind speed and wind utilisation) would then help to show estimated monthly generation, who's figures could then be used to calculate the estimated cost savings and payback period of the turbine(s) and their associated electronics and infrastructure.

Those are probably the main ones. If this is for a small wind turbine for a building (kW range) then a simple analysis with figures and graphs using Excel is fine. If this is for a wind farm consisting of multiple wind turbines (or very large MW producing turbines) you will likely need to use professional software to perform a more complete analysis (such as taking into account wind interference and reduced efficiency from multiple turbines close together, etc), as well as measuring wind data over a much longer duration.
