GPP - A General-Purpose Post Processor for Wind Turbine Data Analysis

David Simms

Research output: NRELTechnical Report


GPP1 (pronounced 'jeep') is a General-Purpose Post Processor for wind turbine data analysis. Engineers in the Wind Technology Division (WTD) of the National Renewable Energy Laboratory (NREL) developed it to post process test data and simulation predictions. GPP reads data into large arrays and allows you to run many types of analyses on the data in memory. GPP runs on inexpensive computerscommonly used in the wind industry. You can even use it on a laptop computer in the field. We 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 use. Exhaustive error trapping prevents you from losing valuable work due to input errors. GPPshould make a significant impact on engineering productivity in the wind industry.
