GPP User's Guide: A General-Purpose Postprocessor for Wind Turbine Data Analysis

    Research output: NRELTechnical Report


    GPP (pronounced 'jeep') is a General-Purpose Postprocessor for wind turbine data analysis. The author, a member of the Wind Technology Division (WTD) of the National Renewable Energy Laboratory (NREL), developed GPP to post process test data and simulation predictions. GPP reads data into large arrays and allows the user to run many types of analyses on the data stored in memory. It runs oninexpensive computers common in the wind industry. One can even use it on a laptop in the field. The author wrote the program in such a way as to make it easy to add new types of analyses and to port it to many types of computers. Although GPP is very powerful and feature-rich, it is still very easy to learn and to use. Exhaustive error trapping prevents one from losing valuable work due toinput errors. GPP will, hopefully, make a significant impact on engineering productivity in the wind industry.
