John Deere and Farmers Team Up to Harvest Wind
Farmers have always been vulnerable to weather and price fluctuations, and John Deere has been supplying them heavy equipment since there was heavy equipment to supply. Now farmers' desire for stable income and access to open land and Deere's financial clout and expertise with large machinery are combining to...

The Use Of Supersaturated Statistical Designs In Product Development
When designing a complex mechanical system there is always considerable emphasis on reducing the time spent determining the best design. Understanding factors contribute to the performance of the system as rapidly as possible is very important. Supersaturated Statistical Designs SSDs offer a potentially useful way to investigate many factors with...

Torque Control for Variable Speed Wind Turbines
An advanced generator control algorithm has been developed and implemented in ECN's control design tool for wind turbines. For wind speeds above nominal the algorithm limits power and rotor speed to the common bounds of constant power control in variable speed turbines, while the electromagnetic torque varies half as much...

Estimated Wind Speed Feed Forward Control for Wind Turbine Operation Optimization
This paper focuses on the prevailing turbine concept variable speed, pitch to vane. For a pitch controlled variable speed wind turbine, a feed forward control structure based on the estimation of rotor averaged wind speed has been developed and analyzed. The additional control action will accelerate ordinary rotor speed feedback...

Frequency Domain Load Calculation for Offshore Wind Turbines (TURBU Offshore)
The design of offshore wind turbines requires assessing a huge amount of different sea states and wind conditions. Therefore the calculation efficiency of a combined time/frequency domain approach is attractive. This was the reason for the development of the frequency domain tool TURBU Offshore. In addition, such a tool is...

Dynamic Inflow Compensation for Pitch Controlled Wind Turbines
In this paper, an algorithm has been developed that provides filter parameters for pitch control loops in order to compensate for dynamic inflow effects. This improves the loop stability, especially near rated conditions. The filter behavior reflects the 'inverse of the normalized' rotor-integral dynamic wake behavior in accordance with the...

More Power and Less Loads in Wind Farms: 'Heat and Flux'
The paper considers a farm as a single energy extracting body instead of a superposition of individual energy extractors i.e. winds turbines. As a result it found two new hypotheses called Heat and Flux. Both hypotheses reveal that the classical operation of turbines in a wind farm at the Lanchester-Betz...

Performance Acceptance Test for a Non-Condensing Turbine Generator Drive Superheated Inlet
This document is a simplified ASME performance test procedure which Dresser-Rand believes is satisfactory for the majority of non-condensing turbines. The instrumentation required for this test is much less costly, and fewer component readings are needed to obtain good results as compared to a full ASME PTC-6 test. In this...

Wind Turbine Development: Location of Manufacturing Activity
Wind, one of the lowest cost renewable energy resources, would be very likely to provide a large part of the renewable energy developed under any national program using these two support mechanisms. Since the best wind resource is in the upper Great Plains region, it is reasonable to conclude that...

The Monitoring, Operation and Assessment of a Semisubmersible Tidal Stream Prototype
Most currently proposed tidal stream turbine concepts are based either on fixed bottom-cantilevered mountings or on tethered floating devices. For the 70% of the available UK resource that occurs in waters of 48m depth or more ETSU estimate, neither of these concepts is likely to be practicable: fixed bottom mounts...
