The Necessity Of Wind Turbine Inverters
Wind turbine inverters are needed to convert the direct current, DC, energy that this natural power source produces into alternating current, AC, energy that can be used by most household devices. The most common example are the grid-tie converters which are a special type designed specifically for use in renewable power systems. These machines go by several different names such as synchronous inverters and the grid-interactive inverter. They are most notable for their ability to take the energy that they have inverted and feed it into the utility grid. Only the necessary energy is used and the surplus is sold to the power company for a profit.
Because wind power generators typically produce direct current power, it must be converted into usable AC power before it can be fed into the power grid. This is where wind turbine inverters come into play. They take the DC power from the source, which is usually in 250 to 600 volts, and invert it into AC power. In addition, they also perform the necessary synchronization of the frequency so it matches that of the grid. These machines are also specially designed to go off of the grid in cases of power outages; this way when the maintenance crew arrives on the scene to fix the wires they are not electrocuted.
In today’s world where fossil fuels are becoming scarce, alternative energy sources such as wind power generators are becoming more popular. Hybrid systems that make use of solar power are also an excellent choice and they too need wind turbine inverters in order to make the energy harvested usable. This way even in cases of low wind or cloudy days you still will be harvesting enough energy to power your house. There are two main classifications when it comes to these devices, those that directly tie into the utility grid and those that have batteries that are charged to provide a source of backup power.
Wind turbine inverters these days rely on several different types of technology, and it can benefit you to know a bit about them before making a purchase. The newest models typically make use of high frequency transformers, but the low frequency transformer models are still more commonly used. The high frequency models use a computerized, multi-stage process for converting the DC energy into usable AC energy at the proper frequency. However, there are also models that do not even use transformers, and as a result they have a lighter weight and higher efficiency. The negative aspect is that they are not largely compatible with the US utility grid.
As you can see, there are many benefits that come with buying and installing wind turbine inverters. This can be an excellent way to lower your dependence on fossil fuels and you may even be able to make a profit by selling your surplus energy to the power company.
