LITE version suitable for analyzing data for up to 30 days.
is a software tool dedicated to the analysis of wind
characteristics (speed, direction, turbulence, temperature). It
is not a standalone program, but an Add-In to
the Microsoft Excel® 2000/XP, for the Windows
9x/ME/NT4/2000/XP operating systems. The results of the analysis
are stored graphically and numerically into spreadsheets, which
can be further used as ordinary Excel files.
program is designed to provide all the results of the data
analysis, in a customizable form to meet any particular needs.
Thus, the user can rearrange all the graphs, resize them, change
their colours, copy or link them to other sheets or programs
(i.e.: embedded links to Microsoft Word® document),
create new tables using the numerical results, etc.
analysis complies with the requirements imposed by the IEC and
- It performs complete
statistical analysis of the wind data, including Weibull
distribution constants (per direction sector and global),
turbulence intensity evaluation and polar plots (wind roses) of
the time and energy distribution of the wind.
- It correlates
data from two sites calculating correlation coefficients globally
and per ranges of wind speed and direction. As a result, it
provides the predicted time-series for the missing data of a
site, based on the other site’s complete set of data (MCP
- It has a user
configurable time step (10 minutes, 1 hour, etc) and it is able
to analyse huge data sets (limited only by the available computer
- A dozen of
power-curves from a variety of wind turbines are included,
providing an estimation of the expected energy production.
- In case of
measurements with systematic errors, a linear correction can be
applied for all the measured quantities and separately for each
- It includes 3
methods for the air-density correction (due to the site elevation
height and to the temperature), which is critical for the correct
calculation of the wind energy.
- It produces
monthly charts and tables with the per hour variation of wind
speed, wind direction, expected wind turbine’s power,
temperature and solar radiation.
How it works
reads ASCII files containing columns of data, an output format
supported by the majority of dataloggers. Five columns of data
are necessary for the program to run: wind speed, wind direction,
standard deviation of the wind speed, time and date. Several
formats are supported when dealing with date and time. Whenever
temperature and/or solar radiation are recorded, then the
appropriate analysis is performed.
