Hi,
I'm studying informatic engineering at college and today
my teacher gave us a project to work in,but I think the project
kind of stupid becuase it's about inofmatic technology and life majors
so my teacher wants us to find any relation between inofmatic technology
and a major of life ,majors have been chosen by accident in
a random way so the major should i work with is power engineering.
I have to work with power engineer for a couple of weeks to create
something usefull but my problem is I don't know any thing about
power engineering and how can i mix it with inofmatic technology,
do you get it?I need some project idea to work on it and it should be
about inofmatic technology and power engineering.
I mean by power engineering electricity power,I'm realy confused about
that but guys I need your help.
Thanx.
power engineering and programming
If you're supposed to work with a power engineer, this would suggest that it's a valid strategy to go to said power engineer, and watch him for a day or something. After watching a power engineer work for a day, you probably know a whole lot more about what they do, and it'll be much easier to come up with something useful.
Or if said power engineer is working for your project, then talk with said power engineer. He could have some ideas, or you could get some ideas by having him explain what they do.

The real problem with goto is not with the control transfer, but with environments. Properly tail-recursive closures get both right.
I think any power engineer will not work with me unless I gave him
a straight idea to work on it,I liked what Candy said so...
would you please Candy expalin more about your idea and about
"network regulating program" becuase I don't have enough knowledge
about networks ,another question what do you mean by microplatform?
is some kind of embaded system or microcontroller?
any links about this I'll be so grateful.
Thanx.

guys listen to this...
I'm thinking of building an electricity network and control this net form
a computer program.
This net consist of let's say "streets" or parts and through our program we can cut electricity from specific street or transfer it from street to another
also this program can tell us if there is any wrong in the net.
I think this idea kind of simple and there is no thing special about it.
what do you think?
Thanx.

Make a program that does that using internal algorithms that indicate "good" things - net load total may not rise above a given value, as much customers as possible should be supplied with power etc. You could allow it to detect shorts (overloads) or cut outs (disconnection - no load) and deal with them similarly, say, by indicating a failure and cutting off the respective section from the net until it's activated again.
You could add multiple sources trying to keep the net loss to a minimum. (transferring power on wires costs power, so the least amount of wire you use in total cuts the cost of the power).
Hi,
When selecting which cable to use you need to take this into account, as it effects efficiency and cost, but also causes voltage drop (where 1000 volts on one end of the cable might end up being 990 volts at the other) and determines the amount of current that can be carried (either before the voltage drop is too much or before the cable is operating out of it's temperature limits).
Also, the amount of current a cable can carry depends on how it's installed. For example, a cable installed in thermal insulation (e.g. in a ceiling) won't be able to dissipate heat well, and would carry much less current than the same cable installed underground before reaching it's temperature limits.
Lastly, sometimes it's cheaper to run pairs of wires. For example, using a pair of 10 mm cables might be cheaper than using one 20 mm cable. Typically the only reason for this is mass production - the smaller cable may be mass produced, while the larger cable might be special order.
Often (for electricians, and I would assume for power engineers) you need to select a cable according to the length, current, voltage drop, how/where it's installed and cost. A utility with information for each type of cable that can be used to find the cheapest cable type for a specific situation (and therefore save the hassle of doing these calculations) may be a suitable project...
From here the utility could be extended to handle other things. For example, for a long run for 1000 V, is it cheaper to buy 2 transformers to convert it to 4000 V and back (and therefore use smaller/cheaper cable)? Then there's switchgear, lightning protection ,etc.
Anyway - just a thought (I am a fully qualified electrical contractor in Australia, but don't have that much idea about high voltage power distribution)..
Cheers,
Brendan
For cables, ohms law applies. This means that the cable itself has resistance (impedance) which is determined by the material it's made from, it's length and it's cross-sectional area. Typically there's tables that list the impedance of different cable types.Candy wrote:You could add multiple sources trying to keep the net loss to a minimum.

For all things; perfection is, and will always remain, impossible to achieve in practice. However; by striving for perfection we create things that are as perfect as practically possible. Let the pursuit of perfection be our guide.

hmm..
for building the electricity net I should:
-following an algorithm for shortest paths (Graph stuff..)
-specification the max voltage and the min voltage so I know
how much the wires resistance must be.
-I should specify the max lenght and where this net is going to be used.
-The most important (I think) selecting the wires type.
That's it am I right?am I missing any thing here?
also what about the program what do you advice me...
what about the programming languages, I think visual basic might
work here(It's easy and simple but I don't like it),I prefer using
C becuase I know it well and I like it also C++ might work here.
Thanx.

power engineer city simulation opengl c c++ electricity
You could use openGL under Win32 and Linux to build a little 3D city using cubes as buildings, with the glBegin(GL_LINES) drawing the wires between the poles and then into the buildings. Have certain things happen at random times such as simulating a car hitting a power pole and actually having the camera zoom into the point where a switch flops opening that part of the system, then other switches open and close to try to reroute the power around the problem.
A brown out could be simulated by reducing the voltage on the city's network for a couple of hours... keep statistics and allow the user to reply the same simulation events and watch from different points.
If you wanted to go crazy you could make a simple dam and terrain using blender, and enable to user to fly to that point and into the dam and see the turbines generating hydroelectric power with statistics floating beside them as the city simulation runs. Someone might want to see what happens during a brown out so research how the voltage is reduced and generated in a hydro electrical dam, then shoot you're self in the foot because this all would be way to complicated to do in a short amount of time.
