Figure 8.5 Effect of a Drive-Train Damping Filter seen to be building up. Although the power and generator torque are smooth, the gearbox would be very badly affected. The effect of introducing a damping filter as described above is also shown. It almost completely damps out the resonance without increasing the electrical power variations. This is because the torque ripple needed to damp the resonance is actually very small, because the amount of excitation is small.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
