Objective
Objectives
To examine the total design envelope criteria of existing selected Wind Turbines for complex terrain operation (Stall 100kW-600kW, Pitch 225kW-500kW, Variable Speed 100kW-450kW, and Teeter 1000kW concepts) in relation to the IEC-1400-1 standard, the wind climate and the complex terrain wind structure; and to investigate the potential for increase in WT energy production and/or decrease in loading that can be attained through feasible WT adaptations; i.e.
to investigate the potential ranges and means of cost reduction for the wind produced electricity in very high wind speed complex terrain sites.
To fully investigate the newest and state of the art rotor designs for selected Stall and Pitch WTs operating on highly complex terrain sites with very high wind speeds and to examine the possibility of control parameters optimization for the Stall, Pitch, Variable Speed and Teeter WTs for the same sites, with the objective to increase WT energy production and/or decrease loading.
To implement the findings of the R&TD work on selected operational Stall, Pitch and Variable Speed WTs (construction, installation and operation of the new rotors and possibly optimized controller parameters) operating on highly complex terrain sites exhibiting high wind speeds and to operate the adapted machines for a minimum of one year.
To fully quantify and verify the performance of the adapted Stall, Pitch and Variable Speed WTs through detailed wind, load, power and machine condition measurement programs on the adapted WTs and to provide definite conclusions on the kWh cost reductions attainable.
Technical approach
The project will integrate all relevant information gathered within the previous complex terrain oriented projects where the differences between the complex and flat terrain wind structure were established, i.e. it will use and enhance the scope of the newly developed 3D fully coupled complex terrain wind turbulence model (CTTM). This information will be enriched with the investigation of the total design envelope (wind climate, extremes, transients, grid, etc.) and with the results of the measurements from the application of the new state of the art rotors to the selected Stall and Pitch WTs. Detailed wind, machine power and loading measurements (CRES, RISO, TG) will be used in parallel to the application of advanced parameter identification techniques (PI) to the measurement databases and to the advanced state of the art computational tools and WT models (CRES, NTUA, RISO, TG) in the full design envelope investigation as it relates to the IEC-1400-1, the wind climate and the complex terrain wind, and in the kWh cost reduction assessment. The new state of the art rotors (stall and pitch) will be installed and operated on selected WTs in Greece and Spain (CRES, RISO) on high speed complex terrain sites. The rotors will be redesigned and constructed to match the specific characteristics of the WTs to be installed on and will be monitored for a minimum of a year. Full WT measurement programs (wind, power, condition) will be performed on the adapted WTs in order to produce the full performance map of the new rotors. Finally the findings from the operation of the new rotors will be evaluated against the results of the design envelope investigation and guidelines regarding the adaptation techniques towards WT kWh cost reduction for the different control strategies will be provided.
Expected achievements and exploitation
Databases for complex terrain wind and wind climate characterization along with databases for WT performance and loading.
A methodology for the full design envelope assessment of WTs for complex terrain operation, and guidelines for the inclusion of the relevant to WT design complex terrain characteristics in the design standards developing world-wide.
Reduced costs of wind energy production through identification of means and ways of increasing energy production and decreasing loading for WTs operating on very windy complex terrain sites.
New rotor designs for stall and pitch WTs and optimization of WT control parameters for very high wind speed operation in complex terrain sites, targeted and expected to reduce the kWh cost of Stall and Pitch WTs by 5%.
