Congrats!

4/23/2008 11:42:19 PM

Can you take a look at this mole on my ass?

4/23/2008 11:43:59 PM

im not a real dr. or anything, but i'll still take a look at your ass

Not necessarily - there's always post-doc work...

4/24/2008 12:07:18 AM

now get off your lazy butt and get a job. what's wrong with you? contribute to society you slacker

4/24/2008 12:08:18 AM

I'll be there some day. We can have a "who has their PhD" role call in old school congrats mr. rev. dr. joenumbers

4/24/2008 12:29:23 AM

Nice! Congratulations Dr. Joe####'s

Congratulation.




You know, they call me Dr. Worm.

4/24/2008 1:12:09 AM

stuff white people like, staying in school forever!

4/24/2008 1:13:43 AM

^ haha, i was one of the two white guys in my group, the rest were indians and asians

i guess not many white people like what I do

4/24/2008 7:26:10 AM

congrats, what was your dissertation?

now i wish i hadn't stopped at a master's.

4/24/2008 7:45:26 AM

congrats

welcome to the dr. club (dues are paid directly to me in this organization)

4/24/2008 7:54:18 AM

If i was a huge dork i'd buy you the SN for graduation..

ohh shit... i might be a huge dork

4/24/2008 7:55:44 AM

you can always go for another degree and stay in school forever....and ever......and ever.....and ever....and ever......

Title:

Computationally Intelligent System and Method for Determining Harmonic Current Contributions from Nonlinear Loads in Power Systems

Summary:

The objective of this research is to introduce a fuzzy neural network based solution for the problem of measuring the actual amount of harmonic current injected into a power network by an individual nonlinear load.

When nonlinear loads are supplied from a sinusoidal voltage, their injected harmonic currents are referred to as contributions from the customer. Harmonic currents which flow in any network, cause harmonic voltage drops, so that the supply voltage at the customer is no longer sinusoidal. Any other customers, even with linear loads, connected to the terminals (called the Point of Common Coupling, or PCC) of the first customer, will have harmonic currents injected into them by the distorted network voltage at the PCC. Such currents are referred to as contributions from the power system, or supply harmonics. Currently no method exists which can reliably distinguish between load harmonics and supply harmonics. The proposed load modeling method addresses this issue. The scheme is verified on a number of different power electronics test circuits as well as field data.

The utility is responsible for ensuring there are no resonance conditions created by their use of capacitors on the system. However, if a significant amount of voltage distortion exists on a circuit, customer loads can have an increased level of current harmonics as a result of the voltage distortion. So, it can be difficult to determine whether a customer is within IEEE519 compliance or not. The proposed load modeling concept is also able to identify the amount of customer injected harmonic current regardless of whether a resonant condition exists on the utility power system.

If several loads are connected to a PCC, another important parameter of interest is to monitor the change in the voltage distortion level at the PCC, if a nonlinear load were to filter out its harmonics. The proposed source modeling scheme addresses this issue.

The intellectual property of this research is protected. This would help the commercialization of the proposed methods. The main advantages of the proposed schemes are that only waveforms of voltages and currents are required for their operation and they are applicable to both single and three phase systems. Both the schemes are designed as software tools and can be integrated into any existing power quality instrument. This could also be fabricated into a commercial standalone instrument that could be installed in substations of large customer loads, or used as a hand-held clip on instrument.

Nice.

How large are the currents required to change the voltage to a threshold it matters?

I work with 3.3VDC , and with bad layout 2A is enough, hahahah.

4/24/2008 8:34:37 AM

congrats

4/24/2008 8:36:37 AM

neural networks, fuzzy logic, genetic algorithms FTW

4/24/2008 8:40:42 AM

congratulations

joenumbers is gonna be motherfuckin PAID.

Ah yeah, dropping loads!

Quinn, I've done some work on up to 500,000 kV, 3.3V is just noise to me

It really depends on the loading system, but we like to limit the change in voltage up to 1% per 90 seconds with a maximum of 3.5% overall. I've measured currents in the thousands of amps that only affected a system voltage by about 1.5%, but on the other hand something as small as 500 A causing a 7%+ fluctuation.

4/24/2008 8:53:47 AM

congrats joe!

i defend tomorrow. no "dr" though. just an MS.

ps- your title made my head hurt. i'm a different kind of science

aawesomeeee! congratulations!

4/24/2008 9:18:03 AM

If smoking is a challenge, I can only imagine how difficult it must be to defend yourself.

4/24/2008 9:49:13 AM

so... if I get a Ph.D in literature we would be even, right?

on level footing?

Congrats Joe!! Maybe one day I will be Dr Amna! Intelligence is powerful and attractive! gg!

4/24/2008 10:28:14 AM

haha the only 2 people who said his title made their head hurt are both chicks

4/24/2008 10:31:01 AM

It makes my head hurt when I read it the way it's typed. I hate how they made me capitalize each word

on another note, when I tell LaTeX to build my paper, it takes it about 10 minutes to assemble the document

4/24/2008 11:45:53 AM

ha

4/24/2008 11:46:31 AM

Wanna get married?

Congrats!!!

4/24/2008 11:52:20 AM

How old are you? You are not 24 years old are you? If so then you are very young to be getting your doctorate.

4/24/2008 12:15:48 PM

i'll be 27 in october

i guess i haven't updated the age profile in a while

4/24/2008 1:00:48 PM

That is still young to be getting your doctorate!

4/24/2008 1:09:01 PM

congrats!

4/24/2008 1:31:57 PM

set'em up

congrats
