1. Introduction
Movies are important as they present new experiences, cultures,

2. places, ideas, and so forth. They are similar to the “campfire”
that people used to gather around to tell and hear stories in the
past. They are a way to step out of our world and into another
world for a brief time, thus allowing us to relieve stress, bond
with our families and loved ones, and so forth.
The drawback to this type of entertainment is that there are so
many different types of movies being produced so quickly by
Hollywood, it can be difficult to choose one to watch. In
addition, parents also find it difficult choosing the right movie
for their children. This is because even though the Motion
Picture Association of America (MPAA) rates movies on
violence, language and drug use, these ratings are often
confusing. Furthermore, with lifestyles being so busy, no one
has time to sit and look through all of the reviews of the new
movies that are coming out and choose the best one to see.
2. OBJECTIVE
The objective of this project is to have a system which assists
customers in choosing and borrowingmovies which they will
return back within a certain timeframe. The movies will be
divided based on genre, MPAA ratings, as well as additional
information, such as current reviews listed from 1-3 stars. The
system will offer three package subscriptions-Basic, Deluxe,
and Supreme. The Supreme package will offer service without
advertisements. It will also offer these services in different
platforms: PCs and video consoles like WiiU, Xbox,
orPlaystation.
3. Benefits
Benefits of providing this service are that customers will be
given five movie choices from which to pick that best suits their
needs at the time. They will not have to waste money buying
movies or going to movie theaters. They will not have to waste
time looking through movie reviews and they will be given
movie choices that are appropriate for their children’s ages. As

3. the younger generations become older, average spending for
these consumers is expected to rise with a potential increase in
their wages, thereby the overall market will demonstrate an
exponential increase in growth in the near future. Additional
plans to include smartphone and tablet moviesfor the upcoming
generations are in the works as well, though not for this project
at this time.
4. PROPOSED TECHNICAL APPROACH
We intend to build a new generation data management system
based on NoSQL’sBigTable, as it was designed for an
organization that works with a variety of data (structured, semi-
structured, and unstructured) that is ever increasing in volume
and needs to be stored, processed, and analyzed. It can also be
compressed. We believe that the use of a data storage system of
this type is more efficient and will also yield superior
performance, high scalability, moderate flexibility, and low
complexity versus a traditional RDBMS.

Single-Phase Operation of an Autonomous Three-
Phase Induction Generator Using a VSI-DL
Control System

Abstract –This paper presents an efficient method to supply
single-phase loads with a three-phase induction generator
(IG). A combination between a properly controlled voltage
source inverter (VSI) and dump load (DL) ensures, besides the
phase balancing of the IG, the voltage and frequency
regulation. The VSI operates at constant frequency – thus
keeping the system frequency also constant - and deals with
unbalances compensation, while the DL performs the voltage
regulation. Simulations are carried out in order to highlight
the reliability of such a configuration.
I. INTRODUCTION
The need for green energy arises from the rapid depletion
of conventional fuels and due to environmental concerns.
This type of energy can be obtained from sources with
unlimited potential (water, wind, sun). It intends to be a
major component in electrical energy generation and will fill
the gap produced by the overgrowing demands from fast
developing economic sectors.
In Romania, energy production from renewable sources is
based mainly on hydro power plants, as the hydrographic
network offers a large unexploited potential for micro and
small plants.
For autonomous micro hydro power plants, the induction
generator (IG) represents the most attractive solution. Its
characteristics (brushless construction, low maintenance and
low capital cost) give it an important advantage over the
synchronous generator. Mainly, the three-phase squirrel-
cage machines are of interest as generators. However, in

11. rural and isolated places with installed powers bellow 10
kW single-phase networks are employed. A need therefore
arises for the use of single-phase induction generators in
these systems. Although all single-phase induction motors
can operate as generator, they may not give the best
performance since they have been designed for optimal
motor operation. To overcome this problem, a specially
designed two winding single-phase SEIG has been studied
[1]. Nevertheless, another inconvenient arises, as the power
of these machines is limited by their constructive
characteristics. They are commonly used at powers up to 3-4
kW.
On the other hand, three phase induction machines are
available in a wide power range and their use for supplying
single-phase micro-grids is of real interest. In order to do
that, some adaptations are required. Over the years, several
topologies have been developed [3-7]. In [3], with the use of
only one capacitor, several types of the Steinmetz
connection are analyzed. The IG behavior when connected
to a single-phase power grid is studied in [4, 5], where the
authors analyze the Smith connection and the use of a
transformer to inject current into the “free” terminal of the
stator winding. For ∆ connected machines, the C-2C
connection is employed, and a control topology is given by
the authors [6]. In [7], for a star connected machine, three
capacitors connected in parallel and series with the single-
phase load ensure the phase balancing. Power electronics is
also used to obtain balanced operation of a three-phase IG
when delivering power to a single-phase grid [2]. A more
expensive solution for the same situation with the one
presented above proposes the use of two back-to-back
converters [8].
In this paper, a VSI and DL combination is used to ensure

12. the balanced operation and parameters regulation of an
autonomous three-phase IG when supplying single-phase
loads. The paper is organized as follows. In section II, the
control system is presented. Section III details the
unbalances compensation algorithm. Section IV shows the
simulation results, while conclusions are provided in Section
V.
II. SYSTEM CONFIGURATION
The circuit diagram of the proposed IG control scheme is
presented in Fig. 1 and follows an experimental scheme
under development. It contains the three-phase IG,
excitation capacitors, the VSI and DL, the single-phase load
and the control system.

13. Figure 1. Circuit diagram of the proposed control system
The excitation capacitors supply almost the entire reactive
power necessary for the IG self-excitation process; they also
sustain the rated voltage in steady-state regime. The IG
control is accomplished by both VSI and DL. The
interconnection between the VSI and the IG is made through
an inductive filter. The dissipative circuit (DL) consists in a
DC chopper and a dumping resistance.
The amount of power delivered to the dump load is
controlled by modifying the PWM duty cycle that drives the
TD transistor.
An additional low-voltage source (Vst-up) in series with a
series diode on the inverter DC side is used for the IG start-
up. This source supplies the initial current required by the
IG to start the self-excitation process.
II. THE CONTROL SYSTEM
The control system is divided into two loops, one
corresponding to the VSI side and the other for the DL.
A. The VSI control
The VSI is a three-phase PWM inverter with six
transistors. Its control requires the generation of six PWM
pulses, which drive the transistor bridge. The VSI operates
at constant synchronous frequency (fn=50Hz), maintaining
the IG frequency constant, excepting the start-up [10].

14. In order to achieve balanced currents at the IG leads the
VSI performs as an unbalance compensator according to the
load. As the loads are varying randomly, the VSI control
must quickly adapt to maintain the IG balance currents. The
control strategy is depicted in Fig. 2.
In the unbalance compensation control scheme the A
phase current is considered as reference and the B and C
current references are obtained by lagging the A current
with 120 and 240 degrees. The unbalances compensation
control scheme contains two stationary-frame regulators
called Proportional-Resonant (PR) controllers, which are
based on stationary-frame generalized integrators. These
regulators report very good performances, actually
achieving the same transient and steady-state performance
as a classical synchronous-frame PI regulator [12].

They have zero-steady-state error and selective input
signal gain. Thereby, if the input signal contains high-order
harmonics they are filtered-out, and only the fundamental is

limit the controller output at the desired maximum value.

B. The DL control
As the frequency is kept constant by the VSI, the system’s
power balance is reduced to the DC capacitor voltage

18. control. The dump load connected to the VSI DC side will
be controlled so that the voltage across the CDC capacitor
remains at a constant level, maintaining the system voltage
in a standard variation range.
Thus, the difference between the power delivered by the
IG and the loads demand will circulate through the VSI
towards the CDC capacitor, which acts as a short-time energy
storage element. The DC voltage variation ratio depends on
the capacitance value and on the amount of power
transferred from the IG towards the capacitor. The capacitor
value plays a very important role during transitory regimes,
when it has to handle large amounts of energy (in or out).
Large capacitors ensure low voltage drops across the IG
lines when dynamic loads (as induction motors) are
connected to the system [9]. Likewise, for unbalanced loads
asymmetrical currents will flow through the inverter lines,
producing voltage variations on the CDC capacitor [10].
Two PI controllers are used to regulate the system
voltage, as shown in Fig. 4. The first PI controller is the
leading voltage regulator. It compensates the voltage drops
across the inverter arms and filter, IG leakage impedances,
and other circuit elements, which usually led to a decrease
of the IG voltage. The IG root-mean-square (RMS) voltage
(VAB) is the feedback signal, it is compared with the 230 V
reference signal (VREF), and the error feeds the PI controller,
giving the reference signal (VDCref) for the second controller.
The second PI is used to maintain constant the CDC voltage.
The allowed voltage variation (ripple) across CDC capacitor
(ΔVDC) will give the frequency and the width of the pulses
that drive the Td transistor from the dump load.

A. The unbalances compensation
First, the simulations are carried out in order to highlight
the efficiency of the unbalance compensation technique. To
do that, two regimes were considered, more precisely
without and with the unbalances compensator. The results
are presented in the figures below.

compensator
The IG supplies a 3000 W single-phase resistive load.
Initially, until t=4.5s, the unbalances compensation function
of the VSI is disabled. Thus, the IG currents are unbalanced,
as can be seen in Fig. 7 – the upper part- ; having values of
9.4, 13 and 16.5 A. This thing leads to significant torque
oscillations, ranging from 0.55 to 1.4 [p.u.] – see Fig. 9-.
The current unbalances also lead to voltage unbalances, but
less significant then the current ones. The phase voltage
waveforms are depicted in the upper part of Fig. 6.

23. At t=4.5s, the unbalances compensation function is
enabled. The two PR controllers respond quickly and
satisfactory, balancing the IG currents in approximately 1
second. Thus, both IG voltages and currents are balanced,
and the electromagnetic torque oscillations are significantly
reduced. The resulting waveforms are depicted in Fig. 6-9.

B. The transitory regime
After the use of the unbalances compensation proved to
be reliable, the transitory regime is further analyzed. As
loads supplied by an autonomous IG are variable by nature,
their effect on voltage and frequency characteristics are of
real interest.

26. Initially, the IG supplies a 1.6 kW single-phase resistive
load. At t=4.5s, a pure resistive load with P=1.5kW is
connected to the IG leads. Its influence on several
parameters is shown in the figures below. After the R load
connection, at t=4.5s, the IG voltage has a little sag (Fig.
10); in consequence, the VSI DC capacitor voltage
decreases as well, the regulators command an increase of the
DC voltage in order to compensate this phenomena. The
voltage drop is small (around 4V), and the voltage regulator
brings the voltage to its rated value in approximately 1
second. The frequency variation is insignificant, as can be
seen in Fig. 11. After the load is connected, the IG currents
tend to become unbalanced, but the unbalances compensator
reacts promptly and stabilizes these currents, in 1.5 seconds
they are all brought back to their rated values. The IG RMS
currents are depicted in Fig. 12.

Figure 12. The IG RMS Currents variation
In Fig.13, the VSI DC current is shown. Before the 1.5
kW load connection, around 4.5 A are passing through the
VSI and dissipated by the DL on the dumping resistance.
After the load is connected at t=4.5s, this current drops to
around 1.2 A, but still the total power supplies by the IG is
bigger then the load demand. Assuming a corresponding 3.3
A difference for 1.5 kW, the idea is it can still supply an
extra 0.5kW charge. Thus, the simulations are repeated for a
2kW load connection in order to establish how the system
behaves at maximum load. The results are presented in Fig.
14-15. The IG RMS voltage decreases a little more then in
the previous case (around 6V), but it is rapidly brought back
to its rated value (see Fig. 14). As for the VSI DC current
from Fig. 15, right after the moment of connection, its
current changes the sign, as for a short period of time (0.2
seconds) the DC capacitor acts as a storage device,
supplying the demanded. As previously mentioned, the
value of the DC capacitor plays a very important role during

30. transitory regimes. In this case, the use of a large value
capacitor (4700uF) proved efficient in ensuring a rapid
system recovery when the total load connected becomes
close to the maximum rated value.

V. CONCLUSIONS
This paper investigates the single-phase operation of an
autonomous three-phase induction generator. The proposed
control strategy employs a combination between a VSI and
DL. Based on the results obtained from the simulations in
the Matlab/Simulink environment, two main conclusions are
drawn:
- the unbalances compensation algorithm of the VSI is
effective, ensuring a balanced operation for the IG
- during transitory regimes, the control system reacts
satisfactory, keeping the frequency and voltage into the
imposed variation range

HOMEWORK ASSIGNMENT #4: RECONSTRUCTING
ARGUMENTS
General Instructions:Reconstruct the arguments in the passages
below, following the argument reconstruction rules on pg. 65 of
your textbook.You may work in groups on this assignment, and
you may turn in group work. Each problem is worth 3 points, so
the highest possible score is 33/30.Due: at the start of class
onTuesday, September 23, 2013
Required Problems:
1. [There is] … no need for setting apart one day in seven as a
holy day, since … all days are God’s. [Ohiyesa, of the Santee
Dakota, 1911, quoted in T. C. McLuhan, Touch the Earth: A
Self-Portrait of Indian Existence. (New York: Outerbridge and
Dienstfrey, 1971), p. 36.]
2. Note:Compost is a mixture of decaying organic substances,
such as dead leaves or manure, used to fertilize soil.
Because it is so dark in color, compost absorbs the sun’s rays
and warms the soil. [Michael Pollan, Second Nature: A
Gardener’s Education. (New York: Dell Publishing, 1991), p.
81.]
3. Many people who are victims of sexual assault do not report
the crime because they are ashamed or scared to share it with
anybody. [Katherine O’Neill, “Recent Sexual Assaults Occurred
in Dorms,” Daily Sundial (California State University,
Northridge), September 23, 2008.]
4. Current world population estimates of Armenians range from
6 million to 8 million. Approximately 3.5 million live in the
Republic of Armenia, so a majority live outside the homeland.

83. [Berge Bulbulian, The Fresno Armenians: History of a Diaspora
Community. (Fresno, CA: The Press at California State
University, Fresno, 2000), p. 6.]
5. Hey, there’s a Dodgers game tonight, so I’m sure there’s
some extra traffic on the 5 through Elysian Park. There’s always
extra traffic there when there’s a Dodgers’ game. [Traffic
Report, KNX (Los Angeles), June 6, 2005.]
6. Hybrid technology is … unsuited to small cars not only
because they are already fuel efficient but also because there
isn’t enough space to accommodate the larger hybrid system.
[Kaho Shimizu, “Different Roads to Eco-Friendly Vehicles,”
Japan Times, May 22, 2007.]
7. In addition to its importance as a traditional art form,
Japanese tattooing is a significant modern phenomenon because
of its major impact on the form and content of temporary
western body art. [Clinton R. Sanders with D. Angus Vail,
Customizing the Body: The Art and Culture of Tattooing.
(Philadelphia: Temple University Press, 2008), p. 13.]
8. Who are struggling significantly to find jobs? Teenagers, and
it’s not because they’re lazy. A new report suggests its because
they’re being under-utilized. [Herb Scribner, “Teens Struggle to
Squeeze into the Job Market,” Deseret News (Utah), March 17,
2014.]
9. If only perfect people could get into heaven, then none of us
would ever go there, because none of us is perfect! [Billy
Graham, “None of Us Is Perfect,” The Kansas City Star,
November 14, 2005.]
10. Note:In this passage, ‘he’ refers to Robert Gibbs, President
Obama’s Press Secretary, who was about to hold his first White
House press briefing.
If he’s not nervous then he’s not a human being. So I know he’s

84. nervous ‘cuz I know he’s a human being. [Joe Lockhart, former
White House Press Secretary, MSNBC, January 22, 2009.]
Extra Credit Problem:
11. There is wisdom in admitting what you don’t know. It is
said that the ancient Athenian philosopher Socrates was told by
the Oracle of Delphi that he was the wisest man in the world.
He didn’t believe her and proceeded to conduct interviews with
Athens’ finest: heads of state, great poets, artists and orators.
He came to the conclusion that these people really didn’t know
anything, and decided that he was the wisest man not because he
was knowledgeable, but because he was the only person wise
enough to admit that he was ignorant. [Andrew Fingerett,
“Making Decisions Based on Charm, Not Politics,” Daily
Sundial (California State University, Northridge), September 9,
2008.]
