David Lough, Application Engineer, Gravitec Systems Inc, Seattle, gravitec.com

A worker scales a ladder with a safety cable, a typical feature in many turbines. The cable’s anchor point at the ladder’s top must meet requirements given by the manufacturer, a figure usually dependent on the maximum number of workers climbing the ladder at one time.

All fall-arrest equipment must meet some sort of standard and pass some tests so equipment manufacturers can ensure end users and employers that the equipment will perform to specifications. These standards (ANSI Z359

Closing up shop... it's been great talking with everyone.

Well I've had a great time talking with everyone and sharing in their experiences with wind power.
I hope this site has been helpful, but with my current obligations I can no longer give the keep turning blog the attention it deserves. 

Next week I will be closing the blog portion of the website down. 
I will still offer photo manipulation work for those who need it and I'll try to keep the running tally of the production from my own skystream on the site as well. 

Thanks again for everyone who supported the site.
I wish you all the best,

Josh

WAsP 10 review

Wind Power News >> 
The latest wind power news headlines, syndicated by rss from a variety of wind energy and industry news sources.


The latest version 10 of Risoe's wind-analysis software WAsP has been released for a few months now, and after working with it for a while I thought I'd post a few thoughts and comments on how it's working.

WAsP is a micro-scale wind modeling software package used to estimate wind speeds over a region based on measured wind speeds at discrete points (typically met masts). WAsP also forms the backbone for other wind packages such as Windfarmer and Windpro. The orographic-flow model used by WAsP is the 'BZ-model' of Troen (1990), which in simple terms places a high-resolution 2D

LIDAR-based wind turbine control system

Wind Power News >> 
The latest wind power news headlines, syndicated by rss from a variety of wind energy and industry news sources.


There's been a little bit of interest in laser based anemometry, or LIDAR, wind turbine control systems. It's been the precept of Risoe's Windscanner program below, and several Risoe-DTU papers at EWEC 2009. It even made this month's Economist technology quarterly. As rotors get bigger, I believe this concept will become more and more import - both for energy production optimisation, and for loads reduction on the blades and drive train.

So what is LIDAR? LIDAR is simply the use of a laser in the same way a RADAR is used, by measuring the time
