差别显而易见啊
一个是converter级的 或者更细到device mosfet igbt之类的
一个是系统级的 就是不在意你的电是哪里来的 怎么来 只在乎怎么供配 控制之类的问题
vt的组 也不是一个人 做两个方向 ...

Theory and practice of E.M. noise coupling; Techniques for noise reduction: shielding, grounding and filtering. Measurement of EMI to comply with government regulation. EMI problems and solutions to switching power supply applications. Design of EMI filter.
ECE 5244: ADVANCED POWER CONVERSION TECHNIQUES
High-frequency resonant, quasi-resonant, and multi-resonant power conversion techniques; zero-voltage and zero-current switching techniques in pulse-width modulation converters and inverters. Pulse-width modulation and frequency modulation; non-linear analysis techniques for resonant and soft-switching converters and inverters. Power factor correction recitifiers and distributed power systems.
ECE 5254: POWER CONVERTER MODELING & CONTROL
Nonlinear modeling of power conversion circuit using discrete and average techniques analysis and design of voltage mode and current mode control; parallel module operation and system interactions; distributed power systems; time domain simulation and frequency domain measurement techniques.
ECE 5274: MODELING AND CONTROL OF THREE-PHASE PWM CONVERTERS

ECE 5984: Application and Design of High-density Multi-phase PWM Converters

This course covers the design as well as key applications of the modern advanced high-density AC multi-phase PWM converters. The detailed state-of-the-art design methodology will be presented, including control, semiconductor device selection, loss calculation, thermal design, protection and auxiliary circuits, and converter system integration. The important interface issues with source and load will also be covered. The application topics will focus on PWM converters for electric machine drives, and will also discuss the converter application in electric power transmission and distribution network, as used in utility and autonomous power systems.

----------------------上面是他们研究生的课程
这么说,我应该把VT cpet归为研究电力电子,而不是电力系统了

for power system, to me the following are some of the topics
I think you are from HUST and i have a friend persuing his master in high voltage insulationwhich is a typical direction in power system.
I strongly recommend you to apply University of Waterloo to focus on power system.
http://www.power.uwaterloo.ca/members.htm
Analysis of Conduction and Breakdown Mechanisms in Insulating Materials under HV Stress
Use of Partial Discharge and other High Frequency Components as Diagnostic Tools for Insulation Failure Analysis
Power and Energy Systems.
High Voltage Engineering Applications to Industrial Processes, and Development of Power Supplies.
High Voltage Testing Techniques.
Pulse Power Applications to Electrostatics Problems.
Distribution systems, high voltage insulation.
Power Quality analysis for distribution systems.


to me VT is like an industrial commany now, and no famous guys in power systems but electronics... i may wrong since some of the topics have conjunctions for sure...

i am at intern work now, so no Chinese available no this computer....hope it is clear for u..

一并感谢ls两位高人的细心解答,其实只怪我太嫩了,对专业方向的发展还只在入门阶段

我本科读的是自动化,也就是LZ第一篇帖子里的control了,但是自己不太喜欢搞控制理论,对系里面自动化所搞的电机控制(ac/dc motor control)比较有兴趣,大一点讲主是电力电子方面了。至于IGBT这些到了器件级的只懂点皮毛。应该不属于你们提到的电力系统里的高压、特高压了

anyway,继续关注本帖,关注寄托~

haha,前一个是你的尾巴,也是你MJ啦~
这几天正在忙着写个简历,每次人长者谈申请的事,总是空对空。别人问我什么时候申请,我说下学期,怎么还没动静,我说还早。。。干脆,写个东东出来,下次再谈有话题
想写个resume,动笔才发现,文学创作难。。。

本帖最后由 jialiangleo 于 2009-6-2 05:37 编辑

Any kind of energy conversion system has three main function parts, that is, source, processor and load~
for wind energy
source gonna be the wind turbine
processor: AC/DC or AC/DC/AC or AC/AC converters (here is the main issure for wind energy research, for example, how to maintain the highest power at output side... (called MPPT techniques), how to increase the efficiency etc.)
load: Dc load, ac load, or the gird (grid connected inverter design is quite hot)

Maybe I will talk abt this next time into detail, but wind energy is not as hot as fuel cell and solar panel in US I think..

谢谢,讲得好清楚,赞。
我的了解是太阳能的成本受材料的限制,短期内无法铺开来。你说的是不是指学术上研究的比较热?
风能在美国是不是发展的相对成熟了,已经广泛应用了?
