Sample Personal Statement for Electrical Power
I often admire the various and marvelous science and technologies
created by man, and also exclaim the rapidly changing developments of
the city that I live in----Shenyang, the largest industrial base in
northeast China. However, when I further inspect such progress and
development, what I am actually seeing is the backwardness of our
domestic electrical power system, especially the distance of over
twenty years in the electric drive and controller system from the
international advanced level in this professional field. The
application of electric system plays a very important role not only in
national production, but also in people's lives and other aspects. But
it is true that our domestic core technology and equipment in this
field have long relied on the import. This reality forces me to try my
best with a strong sense of responsibility to change the current
situation and devote all I have to realizing the dream of harmonious
development between man and energy resource.
I appreciate very much the saying "Interest is the best teacher." From
an early time, I began to take part in many creative activities.
Especially when I was in middle school, I invented an electrical motor
with magnet and clue, and made it as a drive setting in a
remote-controlling model. With this device, I got the first prize in
the Design Contest of our city. This experience greatly aroused my
interest in electric motor and related knowledge so that I chose
Electric Engineering and Automation as my major when I went to
university.
I was soon deeply attracted by the broad range of knowledge that my
undergraduate studies unfolded to me. The courses, such as Basic
Analog Electric Technology, Basic Digital Electric Technology,
Electric Drive & Controlling Principle and Automatic Controlling,
opened for me one gate of another into the core professional technical
theories, and helped me grasp deep and all-round knowledge on electric
motor and its system and controlling.
Meanwhile, I actively undertook every project and tried to put the
knowledge I owned into practice. In the second year at university, I
made full use of the courses Basic Analog Electric Technology and
Basic Digital Electric Technology, to self-design and create a digital
voltmeter successfully in our Digital Electric Laboratory for
automatic system. As a senior student, I designed a power supply
system for factories and with the vector controlling technique I
designed a speed setting controller for electric motors. From all
these, I learnt that, if we regard the class as a palace in which
knowledge is accumulated, then the laboratory should be a golden place
for experience and practice.
I encountered some difficulties when I designed the speed setting
controller for alternating-current motors with the vector controlling
technique. Compared to direct-current motors, alternating-current
motors are simple structured and easily protected with a low cost; but
because the alternating current goes through the winding of stator and
rotor in the alternating-current motors, there should design a speed
setting controller for alternating-current motors. The lectures in my
university I believe have failed to give us a deep introduction about
the vector controlling technique so that I had to collect and consult
a large of materials myself during my designing process, of which most
were the advanced technical information from America, and all these
material and information finally set up a steady theoretical
foundation for my successful project. I used computer simulation in my
experiment to test all through the system, which greatly helped me
increase the efficiency and also avoid many mistakes. In this
experiment, the process of collecting material greatly widened my
views of knowledge; at the same time, the experiment itself put all my
knowledge into the practice creatively. In this way, I gradually
improved my understanding on advanced science and technology and also
increased the theoretical level of practice.
At present, I am practicing at Shenyang Electric Motor Plant. I design
a speed setting system for direct-current electric motor with
Programmable Logic Controller (PLC). During this period, I come into
contact with the core technical parts of the production, and what I
have seen is that there is still large distance between China and the
international market not only in the technology of producing large
electric power system, but also in the complete products. Most of our
key advanced equipment has to depend on importing, for instance, the
domestic self-designed large power vector controlling for electrical
motors has serious problems in its stability so that we have to import
such machines from other countries.
I feel great responsibility on my shoulder to change such situation.
If there is not a strong support of the electric system, there will be
a serious crisis in our products and even in people's everyday lives.
As a result, what I should do now is to study the modern and
professional knowledge on electric motor abroad, and then come back to
my motherland to help her keep up with the international steps of
developed countries.
The University of Clemson, which I am applying for, enjoys a high
reputation in America for its long history and strong capabilities of
science and technology. This university provides its students with
well-equipped laboratories and creates a comfortable condition and
circumstance for scientific researches. I hope that I can have such
opportunity to share this resource, try to study theoretical knowledge
well and put these theories into experiments. With abundant
researching achievements, I will come back to China to promote her
developments in related professional field, shorten the distance of
technical level between her and developed countries, and thus carry
out my own dream into reality.
