SouthWest Wind Power Whisper 100 and 200 Retrofit Kit

Mon, 17 Mar 2008 23:22:35 -0500

This kit allows you to generate charge power below 10mph or 4.4 m/s which is the lower cut-off for the SouthWest Wind Power turbines.

Both the Whisper 100 and 200 use the same DLCC unit. The DLCC (Dump – Load – Charge - Controller) unit has a manual switch configuration setting for the use of 12, 24, 36 and 48 Volts. This retrofit kit allows you to utilize the full output of the Whisper 100 and 200.

Features of the Whisper 100 and 200 Wind Turbine

Hardware Description

Both the Whisper 100 and 200 wind turbines are hardwired with the basic configuration of 24 volts. Additionally the buyer can hardwire the turbine with either 12, 36 or 48 Volts on the top of the wind turbine as shown in the following picture.

Both the Whisper 100 and 200 use the same DLCC unit.
The DLCC unit has a manual switch configuration setting for the use of 12, 24, 36 and 48 Volts.

Description of the Technical Problem with the DLCC unit

On the main board there are 4 IRFB4410 rectifiers soldered. The rectifiers can’t handle a low level Voltage input. This means that the “Gate” is not opening and is not charging the batteries on a hybrid system. For only a wind speed of 10 mph (4.4 m/s) and up will the “Gate” open and then charge the batteries.

In idle mode the wind turbine is running at 3.3 mph (1.47 m/s) to 9.9 mph (4.42 m/s). It is delivering power from the turbine but the DLCC unit is not opening the “Gate” and therefore there no charges to the batteries at low wind speed.

Over 9 months we have calculated, tested and measured that the Gate on the South West Wind Power DLCC unit. We conclude that the Gate is only opening at 400 Watts and a wind speed of 10 mph and up. In the moment when the wind speed decreases to 9.99 mph the Gate closes immediately and no power is charged to the battery.

Power Loss Calculation for one year on the Whisper 100 and 200

Deltech Ltd. has Whisper data over the last 9 months. The data logger was connected to the turbine inputs with the following results:

VAWT advantages
▪ Easier to maintain because most of their moving parts are located near the ground. This is due to the vertical wind turbine’s shape. The airfoils or rotor blades are connected by arms to a shaft that sits on a bearing and drives a generator below, usually by first connecting to a gearbox.
▪ As the rotor blades are vertical, a yaw device is not needed, reducing the need for this bearing and its cost.
▪ Vertical wind turbines have a higher airfoil pitch angle, giving improved aerodynamics while decreasing drag at low and high pressures.
▪ Mesas, hilltops, ridgelines and passes can have higher and more powerful winds near the ground than up high because of the speed up effect of winds moving up a slope or funneling into a pass combining with the winds moving directly into the site. In these places, VAWTs placed close to the ground can produce more power than HAWTs placed higher up.
▪ Low height useful where laws do not permit structures to be placed high.
▪ Smaller VAWTs can be much easier to transport and install.
▪ Does not need a free standing tower so is much less expensive and stronger in high winds that are close to the ground.
▪ Usually have a lower Tip-Speed ratio so less likely to break in high winds.
▪ Does not need to be pointed into the wind, can turn regardless of the direction of the wind.
▪ They can potentially be built to a far larger size than HAWT's , for instance floating VAWT's hundreds of meters in diameter where the entire vessel rotates , can eliminate the need for a large and expensive bearing .
