Wind Generator Designs

Wind power systems have steadily increased in popularity due to increase in demand for alternative energy sources, and the relative drop in prices for wind power products.

If you’re keen about acquiring a wind electric system, or you just have interest in renewable energy, it’s important to know how wind generators work.

Generator design types

Wind generators are designed to make the most of wind speeds at the location where they are installed. Output capacity varies and it generally reflects the overall voltage of the wind electric system. Small to mid -sized power system designs have output of up to 12 volts, while larger systems have output of up to 48 volts.

Average wind speed is the primary factor considered for installing a wind power system at a given site. For optimal performance of a wind turbine, average wind speeds should be 15mph or more. To maximise power output in low speed areas, generators are designed with longer rotor blades.

Alternatively, the blades could be made shorter and wider but many in number, to generate more power. For high speed generators, short, narrow blades made with more durable material are used to minimize damage to the rotor, caused by high speed winds.

In choosing a generator design for a place, a wind speed measurement should first be carried out at that location. A wind speed measurement is done over a period of time, for instance 6 months or a full year, to get a more accurate average for the wind speed.

A speed measurement also helps to establish maximum wind speed at that location. This information is then used to create the best design that can maximise the average wind speed, and also withstand possible damaging effects of wind at maximum speed.

Installation of wind generator systems

The installation of wind turbine generator systems requires a little more attention than other solar power systems. However, wind electric systems are easier to integrate into your home power system. The generator needs to be mounted at a height that is free from obstruction to wind flow, like tall trees and buildings.

If a turbine is small enough, it can be mounted on a rooftop, however, it may cause a lot of inconvenience due to turbine vibrations being transmitted through the building frame. For installations where the vibrations are too strong, rubber vibration dampers are used on the turbine mountings to counter this problem.

In wind generator installations, the general rule is to install the turbine as high as possible for increased efficiency. It is important to understand the fundamentals for fixing the wiring and controls for the wind generator. For instance, consider current rectifiers, whether built in or a stand alone component installed separately.

Wind turbines use rectifiers to convert turbine output energy to direct current for storage in the batteries. Wind generators do not directly generate direct current (DC) like home solar power systems.

Other considerations include load diversion systems, which divert the wind system’s active current load from the battery to an alternate load when the batteries are not charging. Consider a generator that suits your location and power needs.
