Modeling and simulation of the system in MATLAB/Simulink is used to validate the proposed topology and control methodology.
This document discusses power quality issues in electricity distribution systems and solutions using power electronics. It defines power quality as dealing with voltage magnitude disturbances and waveform distortions. Common power quality issues include transients, voltage variations, waveform distortions, and frequency variations. International standards like IEEE 519-1992 establish limits for harmonic distortions. Power electronic solutions for improving power quality include shunt controllers like static VAR compensators (D-SVC) and distribution static synchronous compensators (D-STATCOM), and series controllers like dynamic voltage restorers. D-SVC and D-STATCOM are discussed in further detail regarding their operation and advantages.
Automatic Power Factor Corrector Using Arduino reportSelf-employed
This document describes an automatic power factor corrector system using an Arduino microcontroller. The system measures the power factor of a load by determining the phase difference between the line voltage and current signals. It then calculates the required compensation and switches capacitors from a capacitor bank to normalize the power factor close to unity. This improves the efficiency of the power system by reducing losses. The automatic correction allows for varying loads by adjusting the capacitors proportionately.
IRJET- Mitigation of Current and Voltage Harmonics using MAF based UPQCIRJET Journal
This document describes a proposed system for mitigating current and voltage harmonics using a unified power quality conditioner (UPQC) with a moving average filter (MAF)-based control strategy. The UPQC consists of series and shunt compensators to regulate voltage and current, respectively. A photovoltaic array is connected between the compensators and provides power to the system. Simulation results show the system can effectively reduce the total harmonic distortion of both the supply voltage and current, improving power quality delivered to loads despite nonlinearities. The MAF control technique offers optimal harmonic attenuation without reducing controller bandwidth compared to other filtering methods.
Hardware Implementation of Single Phase Power Factor Correction System using ...IAES-IJPEDS
Rapid increase of consumers in electronics devices and the use of mains rectification circuits inside these electronic devices is the root cause of mains harmonic distortion. Automatic power factor correction techniques can be applied to the industries, power systems and households to make them stable inturns increases the efficiency of system as well as the apparatus. This paper deals with the hardware design of active power factor correction circuit employing boost converter which is used to boost the DC voltages with a controller based on PID control strategy. The pulses given to power switches by pulse width modulation techniques generated by utilizing micro-controller board, Arduino thus obviating the need of complex hardware circuitry. MATLAB/SIMULINK was used to design and tune the PID controller parameters. The simulation results are matching with the predictions and the same was implemented as hardware. The waveforms various test points and across capacitors were obtained, studied and compared with the theoretical waveforms and are found to be in precise proximity of theoretical waveforms.
Mitigation of Voltage Sags & Swells in LV Distribution System Using Dynamic V...IRJET Journal
This document discusses the use of a Dynamic Voltage Restorer (DVR) to mitigate voltage sags and swells in a low voltage distribution system. A DVR is a custom power device that uses a PWM inverter and injection transformer to inject compensating voltages into the distribution system. This allows it to maintain the load voltage at a nominal level during faults by compensating for voltage sags and swells. The document presents the configuration and working of a DVR, provides simulation results showing a DVR compensating for consecutive voltage sag and swell events, and discusses the benefits of DVRs for improving power quality.
Impact of APFC Panel at LT Side of TransformerIJERA Editor
The Development of automatic sensing technologies have significantly advanced in recent years in electrical systems.One of them is Automatic Power Factor Correction(APFC)Panels.It is very difficult to maintain consistent power factor by using fixed capacitors because they need to be operated manually which may result in over voltages,saturation of transformers etc. that may lead to the interruption in the power supply of the distribution system.APFC Panels automatically varies according to the load requirements on the L.T side i.e. distribution side which compensates the load requirements.Impact of automatic power factor correction panels (APFC) at L.T side of a transformer are discussed which are inductive in nature.
Unified power quality conditioner for compensating power quality problem adIAEME Publication
This document describes a proposed Adaptive Neuro-Fuzzy Inference System (ANFIS) based Unified Power Quality Conditioner (UPQC) to improve power quality compensation performance. A UPQC uses two voltage source inverters to compensate for both voltage and current disturbances but has high DC link capacitor discharge times. The proposed system adds an ANFIS device to generate a bias voltage that maintains the DC link voltage at a lower level. ANFIS combines neural networks and fuzzy logic to approximate nonlinear functions from numerical and linguistic data. The generated fuzzy rules are trained using a neural network to produce the desired output. Analysis shows the proposed ANFIS-based UPQC provides better power quality compensation than controllers using neural networks,

Every electric load that works with
magnetic fields (motors, chokes,
transformers, inductive heating, arc
welding, generators) produces a vary-
ing degree of electrical lag, which is
called inductance. This lag of inductive
loads maintains the current sense (e.g.
positive) for a time even though the
negative-going voltage tries to reverse
it. This phase shift between current
and voltage is maintained, current and
voltage having opposite signs. During
this time, negative power or energy
is produced and fed back into the
network. When current and voltage
have the same sign again, the same
amount of energy is again needed to
build up the magnetic fields in induc-
tive loads. This magnetic reversal
In AC networks (50 /60 Hz) such a
process is repeated 50 or 60 times a
second. So an obvious solution is to
briefly store the magnetic reversal
energy in capacitors and relieve the
network (supply line) of this reactive
energy. For this reason, automatic

General
The increasing demand of electrical
power and the awareness of the
necessity of energy saving is very up
to date these days. Also the aware-
ness of power quality is increasing,
and power factor correction (PFC) and
harmonic filtering will be implemented
on a growing scale. Enhancing power
quality – improvement of power factor
– saves costs and ensures a fast
return on investment. In power distrib-
ution, in low- and medium-voltage
networks, PFC focuses on the power
flow (cos Ø ) and the optimization of
voltage stability by generating reactive
power – to improve voltage quality and
reliability at distribution level.

Power Quality Solution strategy
Along with the emerging demand for
power quality and a growing aware-
ness of the need for environmental
protection, the complexity in the ener-
energy market is increasing: users and
decision-makers are consequently
finding it increasingly difficult to locate
the best product on the market and to
make objective decisions. It is in most
cases not fruitful to compare catalogs
and data sheets, as many of their
parameters are identical in line with
the relevant standards. Thus operating
times are specified on the basis of
tests under laboratory conditions that
may differ significantly from the reality
in the field. In addition, load structures
have changed from being mainly linear
in the past to non-linear today. All this
produces a clear trend: the market
is calling increasingly for customized
solutions rather than off-the-shelf
products. This is where Power Quality
Solutions come into the picture. It
offers all key components for an
effective PFC system from a single
source, together with:
Application know-how
Technical skills
Extensive experience in the field of
power quality improvement
A worldwide network of partners
Continuous development
Sharing of information
These are the cornerstones on which
Power Quality Solutions are built. On
the basis of this strategy, EPCOS is
not only the leading manufacturer of
power capacitors for PFC applications
but also a PQS supplier with a century
of field experience, reputation and
reliability.

5. Important Notes
The following applies to all products named in this
publication:
1. Some parts of this publication containstatements about
the suitability of our products for certain areas of appli-
cation. These statements are based on our knowledge
of typical requirements that are often placed on our prod-
ucts in the areas of application concerned. We neverthe-
less expressly point out that such statements cannot be
regarded as binding statements about the suitability
of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual
customer applications or less familiar with them than
the customers themselves. For these reasons, it is always
ultimately incumbent on the customer to check and decide
whether an EPCOS product with the properties described
in the product specification is suitable for use in a partic-
ular customer application.
2. We also point out that in individual cases, a malfunc-
tion of electronic components or failure before the
end of their usual service life cannot be completely
ruled out in the current state of the art, even if they are
operated as specified
. In customer applications requiring
a very high level of operational safety and especially in
customer applications in which the malfunction or failure
of an electronic component could endanger human life or
health(e.g.in accident prevention or life-saving systems),
it must therefore be ensured by means of suitable design
of the customer application or other action taken by the
customer (e.g. installation of protective circuitry or
redundancy) that no injury or damage is sustained by third
parties in the event of malfunction or failure of an electronic
component.
3. The warnings, cautions and product-specific notes
must be observed.
4. In order to satisfy certain technical requirements,some of
the products described in this publication may contain
substances subject to restrictions in certain jurisdictions
(e.g. because they are classed as hazardous).
Useful information on this will be found in our Material
Data Sheets on the Internet (www.epcos.com/material).
Should you have any more detailed questions, please
contact our sales offices.
5. We constantly strive to improve our products. Conse-
quently, the products described in this publication
may change from time to time.The same is true of the
corresponding product specifications. Please check
therefore to what extent product descriptions and speci-
fications contained in this publication are still applicable
before or when you place an order.
We also reserve the right to discontinue production
and delivery of products. Consequently, we cannot
guarantee that all products named in this publication will
always be available.
The aforementioned does not apply in the case of
individual agreements deviating from the foregoing for
customer-specific products.
