MODELLING AND CONTROL OF STANDALONE WIND ENERGY CONVERSION SYSTEM Published in IJAET Volume 6 Issue 6
BOUZID Mohamed Amine1, MASSOUM Ahmed1,
ALLAOUI Tayeb2, ZINE SOUHILA3
ABSTRACT
In this paper, a Wind
Energy Conversion System (WECS) is discussed. The power conversion system consists
of a Permanent Magnet Synchronous Generator (PMSG), a rectifier and an inverter
connected to the grid. An intermediate DC bus exists between the rectifier and
inverter. This conversion system use the PMSG because of its high performances,
small size and its low weight compared to induction generators. The generator
torque is controlled according to the generator speed and thus the power from a
wind turbine settles down on the maximum power point by the MPPT control
method. Modeling and Simulation of all the components has been done in
MATLAB/Simulink.

Abstract
Hydroelectric power
contributes around 12.45 percent of the electricity supply in India. It is
considered to be the most vital, unpolluted, emission-free and an inexpensive
renewable source of energy. Hydroelectric power-plants operating all over the
world aims to have high electric output with minimum maintenance cost. It’s
very different with Koyna Hydropower Plant (KHPP) stage IV which generates
lower electric output than the installed capacity with higher maintenance. This
project aims to build a simulation model which can simulate the regular
operation of Koyna Hydropower Plant with Arena®. The study involves to evaluate
dynamic response of the system and plant performance under various operating
conditions such as head height, quantity of water flow penstock and operating
gates. Also to determine and identify the optimum parameters required for
maximum power generation. The outcomes of the model helped to analyse the power
generation capacity against the required quantity of water flow and head
height. The developed simulation model was validated and used as an apparatus
to determine the optimal operating parameters that maximise power generation of
stage –IV at Koyna Hydropower plant.

Abstract
This paper presents the application of Compressive
Sensing (CS) theory in radar signal processing. CS uses the sparsity property
to reduce the number of measurements needed for digital acquisition, which
causes reduction in the size, weight, power consumption, and the cost of the CS
radar receiver. Complex Approximate Message Passing (CAMP) algorithm is a fast
iterative thresholding algorithm which is used to reconstruct the undersampled
sparse radar signal, and to improve the Signal-to-Noise Ratio (SNR) of the
radar signal [12- 16]. The superiority of applying the CAMP algorithm in radar
signal processing compared to the Digital Matched Filter (DMF), and the simple
envelope detector is proved through the Receiver Operating characteristic (ROC)
curves. On the other hands, complexity and time of calculation are critical
issues which must be considered.
Keywords: Compressive Sensing, CAMP algorithm, Radar.
ESTIMATION OF STRESS-STRENGTH MODEL FOR GENERALIZED INVERTED EXPONENTIAL DISTRIBUTION USING RANKED SET SAMPLING PUBLISHED on IJAET Volume 6 Issue 6
Estimation of Stress-Strength Model for Generalized
Inverted Exponential Distribution using Ranked Set Sampling

ABSTRACT
In this paper, the estimation of R=P(Y < X), when X and Y are two
generalized inverted exponential random variables with different parameters is
considered. This problem arises naturally in the area of reliability for a
system with strength X and stress Y. The estimation is made using simple random
sampling (SRS) and ranked set sampling (RSS) approaches. The maximum likelihood
estimator (MLE) of R is derived using both approaches. Assuming that the common
scale parameter is known, MLEs of R are obtained. Monte Carlo simulations are
performed to compare the estimators obtained using both approaches. . The
properties of these estimators are investigated and compared with known
estimators based on simple random sample (SRS) data. The comparison is based on
biases, mean squared errors (MSEs) and the efficiency of the estimators of R
based on RSS with respect to those based on SRS. The estimators based on RSS is
found to dominate those based on SRS.
Keywords: generalized
exponential distribution; reliability; stress-strength; ranked set sampling,
simple random sampling; maximum likelihood estimators.

Introduction
The
estimation of reliability is a very common problem in statistical literature.
The most widely approach applied for reliability estimation is the well-known
stress-strength model. This model is used in many applications of physics and
engineering such as strength failure and the system collapse. In the
stress-strength modeling, R=P(Y < X) is a measure of component
reliability when it is subjected to random stress Y and has strength X. In this
context, R can be considered as a measure of system performance and it
is naturally arise in electrical and electronic systems. Another interpretation
can be that, the reliability of the system is the probability that the system
is strong enough to overcome the stress imposed on it. It may be mentioned that
R is of greater interest than just reliability since it provides a
general measure of the difference between two populations and has applications
in many areas. For example, if X is the response for a control group, and Y
refers to a treatment group, R is a measure of the effect of the
treatment. In addition, it may be mentioned that R equals the area under
the receiver operating characteristic (ROC) curve for diagnostic test or biomarkers
with continuous outcome, see; Bamber, [1]. The ROC curve is widely used, in
biological, medical and health service research, to evaluate the ability of
diagnostic tests or biomarkers and to distinguish between two groups of
subjects, usually non-diseased and diseased subjects. For complete review and more
applications of R; see [2-14].
Ranked
set sampling (RSS) is a sampling protocol that can often be used to improve the
cost and efficiency for experiments [15]. It is often used when a ranking of
the sampling units can be obtained cheaply without having to actually measure
the characteristics of interest, which may be time consuming or costly [16,17].
Such a technique is well received and widely applicable in environmental applications,
reliability and quality control experiments [18-20]. A modification of ranked
set sampling (RSS) called moving extremes ranked set sampling (MERSS) was
considered for the estimation of the scale parameter of scale distributions [21]
and an improved RSS estimator for the population mean was obtained [22]. On the
other hand, Ozturk has developed two sampling designs to create artificially
stratified samples using RSS [23]
Recently,
many authors have been interested in estimating R using RSS. For
example, Sengupta and Mukhuti [24], considered an unbiased estimation of R using
RSS for exponential populations. Muttlak and co-authors [25], proposed three
estimators of R using RSS when X and Y independent
one-parameter exponential populations. In a RSS procedure, m independent
sets of SRS each of size m are drawn from the distribution under
consideration. these samples are ranked by some auxiliary criterion that does
not require actual measurements and only the ith smallest observation is quantified from the ith set, i = 1,2,…,m. This completes
a cycle of the sampling. Then, the cycle is repeated k times to obtain a
ranked set sample of size n = m k .

ABSTRACT
Today, almost all fields of human activities rely on
the high-speed broadband technologies for their day-to-day activities. The
banks for example, are making plans to implement better and more sophisticated
services such as cashless banking and other e-transactions as part of the NMT
development goals. The 3G network coverage has become a problem in most rural
and parts of the urban cities in Nigeria. However, the national mobile
telecommunication development goals cannot be achieved without addressing the
issue of 3G coverage in the country. The objective of this paper is to
investigate the 3G technologies, their applications and the situation in developing
nations especially Nigeria. The NMT development was reported to lag behind in
the global telecommunication development and 2G networks are still more prevalent
in most areas than 3G networks. It was concluded that the full deployment and
coverage of 3G network will enhance the success of the NMT goals.

Introduction
Information and Communication
Technology uptake has continued to grow worldwide [1], with 3G technology [2] as
the key or the major driving force towards this achievement and growth. Mobile Broadband is an exciting new
technology that allows connection to the Internet without the usual ADSL router
and telephone line setup. Using the connection is not limited in the house - as
the name suggests it allows connection while mobile as it uses wireless
technology, so that the Internet and e-mail can be accessed anywhere (as long
as the 3G signal is available). Therefore the usage of the 3G service depends
on the availability of the 3G signal in an area.
3G is a term used to represent the third generation of mobile telecommunications
technology [2; 3]. This is a set of standards used for mobile devices
and mobile telecommunication services and networks that comply with the International Mobile Telecommunications-2000
(IMT-2000) specifications by the International Telecommunication Union
[3]. 3G finds application in
wireless voice telephony, mobile Internet access, fixed wireless Internet
access, video calls and mobile TV [4]. Several telecommunication companies
market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G
wireless network. Services advertised as 3G are required to meet IMT-2000
technical standards, including standards for reliability and speed (data
transfer rates). To meet the IMT-2000 standards, a system is required to
provide peak data rates of at least 200 kbit/s (about 0.2 Mbit/s) [4]. Recent
3G releases often denoted 3.5G and 3.75G, also provide mobile broadband access
of several Mbit/s to smartphones and mobile modems in laptop computers. There
are standards that are typically branded 3G which will be extensively used in
this work which include UMTS (Universal Mobile Telecommunication System) and
CDMA2000 (Code Division Multiple Access-2000).
