Wind-Turbines Software 2

Homes use approximately 9,400 kilowatt-hours (kWh) of electricity per year (about 780 kWh per month). Depending upon the average wind speed in the area, a wind turbine rated in the range of 5 to 15 kilowatts would be required to make a significant contribution to meet this demand

WAsP software
WAsP is a PC program for the analysis of wind data as well as wind atlas generation, wind resource assessment, wind resource mapping, and the siting of wind turbines and wind farms. The program, which is continually updated by the Wind Energy Department, is regarded as the industry standard. Over the last 20 years, WAsP has been employed in more than 100 countries and territories. It is used by wind turbine manufacturers and other companies and consultants in the wind power industry as well as universities, research institutions, and meteorological services. The tools and models in the WAsP package can be employed for: Wind farm production Wind farm efficiency Micro-siting of wind turbines Power production calculations Wind resource mapping Wind climate estimation Wind atlas generation Wind data analysis & display Map digitisation & editing Power & thrust curve editing The latest version is WAsP 9. This version contains new functionality, an improved user interface, an updated help facility and several new or updated auxiliary software packages. The most profound changes can be listed under the following headings: Nested wind farms Wind farm power curve Reference site in wind farm Spatial image underlays Resource grid masking Resource grid performance improvements Grids of DRIX values Obstacles in resource grid calculations Enhanced Map Editor with comprehensive roughness map consistency checks New WAsP Climate Analyst tool The graphical user interface of WAsP 9 is illustrated in the graphic below.

Sizing Small Wind Turbines
Small wind turbines used in residential applications typically range in size from 400 watts to 20 kilowatts, depending on the amount of electricity you want to generate. A typical home uses approximately 9400 kilowatt-hours of electricity per year (about 780 kWh per month). Depending on the average wind speed in the area, a wind turbine rated in the range of 5–15 kilowatts would be required to make a significant contribution to this demand. A 1.5-kilowatt wind turbine will meet the needs of a home requiring 300 kilowatt-hours per month in a location with a 14 mile-per-hour (6.26 meters-per-second) annual average wind speed. To help you determine what size turbine you'll need, first establish an energy budget. Because energy efficiency is usually less expensive than energy production, reducing your home's electricity use will probably be more cost effective and will reduce the size of the wind turbine you need. Wind turbine manufacturers can help you size your system based on your electricity needs and the specifics of local wind patterns. A manufacturer can provide you with the estimated annual energy output of a turbine as a function of annual average wind speed. The manufacturer can also provide information on the maximum wind speed at which the turbine is designed to operate safely. Most turbines have automatic overspeed-governing systems to keep the rotor from spinning out of control in very high winds. The height of a wind turbine's tower also affects how much electricity the turbine will generate. A manufacturer should help you determine the tower height you will need.

Windsurvey software
The Windsurvey software is designed to run on a standard PC under Windows XP or Vista. It runs 24 hours a day, gathering data in the background. It does not interfere with any other software you may run (word processors, web browsers etc), except that it ties up one USB port. If you need to shut down the Windsurvey software at any time, the data already gathered is not affected. No data is gathered while the software is not running, but data gathering restarts as soon as the software is restarted. You can select: The model of wind turbine for which the power output is to be displayed. An alternative is to display daily average wind speeds. The units in which the current wind speed is to be displayed. The altitude above sea level, which is needed for the power output calculation. Whether or not a 'standardised' power curve is to be used. Details in the user manual. You can click a button to produce a full report from the entire recorded database, containing daily average and maximum wind speeds and predicted output for all supported wind generators. The full report function also takes copies of the raw wind speed data files (10-minute average wind speeds, also wind data in a format suitable for power output calculations). You can use these files to carry out your own analysis using a spreadsheet or other software. If the model of wind turbine you have in mind is not on the list, please get in touch, as it can probably be added (some manufacturers are more forthcoming than others as regards power output data).

Westwind Wind Turbines
Westwind is an internationally renowned manufacturer of high quality and robust 3kW, 5kW, 10kW and 20kW wind turbines. Westwind have supplied turbines, towers and turbine controllers for use in many different applications around the world since 1984 Westwind turbines enjoy the reputation as one of the most heavy duty and robust turbines available. This makes them the ideal choice for remote area applications where maintenance is expected to be infrequent and or costly. The turbines are designed for strength, simplicity, and low maintenance as the major design criteriaAll Westwind wind turbines consist of three blades, up wind of the tower on a horizontal axis and attached directly to a sealed permanent magnet generator.Rotor over speed protection is achieved via auto furling. The turbine can also be manually furled at the base of the tower. Furling describes the action of the tailboom pivoting around to be at right angles to the axis of rotation. This action turns the blades out of the wind and thereby reduces power output.Previous Westwind designs in the 2.5 to 10KW range utilised pitch weights as an additional control measure. The new blade profile used in the mk2 machines as well as being more efficient is mechanically much stiffer. This means the pitch weights are no longer necessary. They contributed significantly to the aerodynamic noise of the blades so now our machines are barely audible

AeroGen Wind Generators
These well-known wind generators are manufactured here in the UK by LVM, a company with over 15 years experience making wind turbines. They have been used all over the world by yachtspersons, research institutes and by Military Forces. Features: Powerful Performance - Designed for all wind speeds. Compact Efficient Robust Light Maintenance Free Quiet Safe Efficient Brushless alternators Easy Installation - Mounting Kits available.

Marlec Wind Generators
Marlec manufacture small battery charging wind turbine generators The Rutland 503 Rating: 25 W in a 22 mph (10 m/s) wind Voltage: 12 Volts DC Rotor Diameter: 0.51 Cut In Windspeed: 6.6 mph (3.0 m/s) This compact wind generator, is ideal for use on yachts or touring caravans etc, where ease of installation, a light weight and size are important considerations. With a turning radius of 255mm and a unique outer ring around the blade tips it can safely be installed on a confined boat deck. The machine is centrally supported so performance is unaffected by a pitching sea. Stainless steel fasteners and marine grade materials are used throughout. It starts charging in 6.6mph (3.0 m/s) winds and will give a maximum output of over 60 W. It is designed to mount onto 1.25" (31.7mm) internal diameter aluminium tube and an adaptor is available for permanent land based installations using taller towers
