This report suggests that the Darrieus vertical-axis wind turbine may be particularly well-suited for driving a synchronous generator in parallel with a synchronizing electrical power network. Aerodynamic characteristics of the Darrieus wind turbine can be such that no torque regulation mechanisms are required on the turbine, providing the generator is properly sized. Synchronization to maintain constant turbine rotational speed under any wind conditions is provided by the network. To point out operational differences, a discussion is included of synchronous power generation usin...

The study of VAWT technology at Sandia National Laboratories started in the 1970’s and concluded in the 1990’s. These studies concentrated on the Darrieus configurations because of their high inherent efficiency, but other configurations (e.g., the Savonius turbine) were also examined. The Sandia VAWT program culminated with the design of the 34-m ‘Test Bed’ Darrieus VAWT. This turbine was designed and built to test various VAWT design concepts and to provide the necessary databases to validate analytical design codes and algorithms. Using the...
FloWind Corporation for Sandia National Labs, Sept. 1996
Under the auspices of the “Government/Industry Wind Technology Applications Project” [“Letter of Interest” (LOI) Number RC-1-11101], FloWind Corp. has successfully developed, tested, and delivered a high-energy rotor upgrade candidate for their 19-meter Vertical Axis Wind Turbine. The project included the demonstration of the innovative extended height-to-diameter ratio concept, the development of a continuous-span singlepiece composite blade, the demonstration of a continuous blade manufacturing technique, the utilization of the Sandia National Laboratori...

The Sandia Legacy VAWT Research Program
Dale E. Berg, September 2016, Sandia National Laboratories
This slide deck was present to Delft Technical University by Dale Berg who was a principal researcher of the Darrieus type VAWTs that Sandia National Laboratories worked on from the 1970s through the 1990s. It covers the history of Sandia's work on VAWTs including their efforts to develop validated aeroelastic modeling.

This paper, based on the pursuit of scientific articles published and recorded in the last five years (2010-2014) patents on VAWT technology, gives an image of the current situation of the treated technology. From data extracted we know: The different models that are working with different geometries, distinguishing between Savonius, Darrieus, hybrid of both (D+S), models dedicated to Offshore technology and what can be applied generally (D&S) on both types of VAWT (controllers, electric generators, materials ...).The main countries that research and develop VAWT technology, globally and...

In these Master Thesis a review of different type of vertical axis wind turbines (VAWT) and an preliminary investigation of a new kind of VAWT are presented. After an introduction about the historical background of wind power, the report deals with a more accurate analysis of the main type of VAWT, showing their characteristics and their operations. The aerodynamics of the wind turbines and a review of different type on generators that can be used to connect the wind mill to the electricity grid are reported as well. Several statistics are also presented, in order to explain how the importance of the wind energy has grown up during the last decades and also to show that...

This document is a slide show that summarizes Sandia National Laboratories' work on the Darrieus-type VAWTs from the 1970s through to the commercialization of this VAWT technology with the FloWind VAWTs in the 1980s and 1990s. It is a slideshow presentation of the work in A Retrospective of VAWT Technology by Sutherland, Berg and Ashwill
