Spanish Energy Comsuption & Production.

September 4, 2010

Finally, we started our Master on Wind Power at Gotland University. After the student presentations, we had some lectures, readings and homeworks. A lot of homeworks.

In our first week, we need to introduce our country and the present situation related to the Energy Comsuption and Production. Here is my presentation.

Power Electronic Concepts in Wind Turbines.

July 10, 2010

In recently years, we have lived big discoveries on the Power Electronic field that unveil new opportunities to improve the performance in the electric circuits and therefore, in Wind Power industry. Power Electronic can be defined as the brand of the electrical engineering which studies the control and conversion of electric power. Therefore, the power conversion systems can be classified according to the type of the imput and output power:

Here we are the basic components in the Wind Power industry.


Active and Reactive Power.

At this moment, the book I most admire on the Wind Power field, it is this one written by Ackermann. He can transmit dept concepts of power systems by using a clear vocabulary and illustrative examples. In this book, for example, there is an appendix in the chapter three, that explains in a very easy way how the Power System works by using a long bike as an equivalent.

Imagine a long bike with much cyclists running on a flat and straight road. We are the manager of this team and we want to keep the bike at a constant speed (the same frequency) and in an upright position (the nominal voltage equals to 1). How can we achieve this?
