As seen in last lecture, the chosen method for power generation depends mainly on the available power grid system. So, i found this article that might help you understand how important this fact is in power generation and more importantly, how it works!

If you have any question, do not doubt in asking!
As you can see, one of my main purposes in this course is try to make you understand how important English is for us as modern engineer! So let's get this game started... If the article you write in this blog is made in english I'll give half a point instead of a quarter.. Sounds fair to me!
Take care... Eng. Alfredo A. Alvarez G.
PS: This is the first and last time I translate an article!!!
TRADUCCIÓN
Como vimos en la última clase, el método de generación de potencia que seleccionamos depende en gran medida de la red de suministro electrico disponible. Buscando en internet, encontré un artículo que los ayudará a entender cuán importante es este aspecto en la generación de potencia, pero más importante aún, el cómo funciona.

Cómo pueden ver, uno de mis principales propósitos en este curso es hacerles enternder la importacia del inglés para nosotros como ingenieros modernos. Así que comencemos un juego! Si el/los artículos que escriban están hechos en inglés, valdrá medio punto extra en la materia en vez de un quarto. Suena justo para mi...
Saludos... Ing. Alfredo A. Alvarez G.
PD: Esta es la primera y última vez que traduzco un artículo!!

hi there i've just seen this article and it's pretty much interesting and very important as well , if you don't understand anything at all you can use google for translation there are also some videos that would help a lot.
please keep this blog posted for news :)
by the way this is awesome alfredo good work..

I'm glad you like this method!!! If you guys have any other idea just let me know!
Alfredo A.
your idea is good.
if we translate the articles
we gain points?
No dude i dont think so. i guess you have to post new articles and if you do it in english you'll gain half point, in spanish is a quater of point.

As far as I’ve read I agree with the article about we don’t really think about electrical power until it is missing. It says that power travels from a power plant to our houses through a power distribution grid and that our brains ignore the power lines because it is something that we have seen too many times.
Electrical power starts at the power plant and in almost all cases, the power plant consists of a spinning electrical generator and another machine like a steam turbine has to spin the generator. But no matter what spins the generator, commercial ones of any size generate what is called 3-phase AC power, which is simply three single phases synchronized and offset by 120 degrees. And AC or alternative current is used instead of DC because large electrical generators happen to generate AC naturally, so conversion to DC would involve an extra step; another reason is that transformers must have alternating current to operate and it is easy to convert AC to DC but it is expensive to convert DC to AC.
There are four wires coming out of a power plant that are the three phases plus a neutral or what we call ground that is literally the ground that is all around us when we are walking outside because the power company essentially uses the earth as one of the wires in the power system. The earth is a pretty good conductor and it is huge, so it makes a good return path for electrons.
I’ll keep reading and then post another comment……
Is amazing to learn about things that you see everyday and you didn't realise how big are these, We always use electricity and in this time we can't live with out that and everybody must now how hard and big is this process because it isnt't just for people who study electricity it's for everybody since mechanical engineer until anybody because this help to understand and realise that energy is not made by magic is a big process than help us to live confortable everyday in our live.
PD: Raul that's a resume or what? haha... No, it was great!
Good post Alfredo I hope more profesors do this, it is a good way to improve ours knowledge
I think it's okay the way you try to teach us about how power grids work or something related to power generation. Besides learning about power generation we improve our english with this good technique and is important because make us a very good professionals in the future. As Yeli said, it would be interesting if all the professor tried to do something like this.
hey yeli don't mess with me :(
you are so right about this, it is so amazing to learn how this daily stuffs works and we have lived all these years just turning on/off the switch without knowing what really happens before that.... and we have to appreciate what alfredo is doing coz is the only teacher trying to do innovative things....

hey what's up guys and teacher how are you? i just read this comments and i think is fine your idea en your method teacher, but i like to watch some videos about HOW POWER GRIDS WORK? and also some videos about boilers, turbines and how they works... good luck and keep going with this!

Hey guys! What's up? I'm amazed how good your english skills are... Don't you ever stop practicing!!!... I'm glad you enjoy this new method and it's awesome for me to be part of your learning process!!! I promise I'll keep on bringing new stuff to this site!!
Take care!!
