Power Quality Education and Training
One of the fundamental challenges facing utility and
power customer personnel is the need to become
familiar with and stay informed about issues dealing
with power quality. As the utility industry undergoes
restructuring and as customers find their service needs
changing with increased use of equipment and
processes more susceptible to power system
disturbances, power suppliers and customers alike will
find a solid background in power quality not only
useful, but also necessary for continued productivity
and competitiveness
Electrotek Concepts® offers a number of seminars
focusing on various aspects of power system
disturbances, monitoring, mitigation technologies,
simulation and modeling, and power quality program
development and administration. Aimed at engineers,
managers, and other technical professionals, these
seminars can either provide you with a base of
knowledge on the subject, or serve as a refresher for
new concepts and technologies.
The seminars are designed to be presented at your
facility, one of our offices, or off-site at a location of
your choosing. These seminars present both a
theoretical as well as practical approach. While the
seminars feature a set format and agenda, we can
customize them to emphasize certain topics or include
additional material.
Available seminar topics include
• Overview of Power Quality
• Electric Power Systems Quality
• Distribution Power Quality
• Contemporary Topics in Power System
Harmonics
• Utility Capacitor Applications and Concerns
• Power Quality in the Industrial Environment
Adjustable Speed Drive Application
Considerations
• Efficient Motor and Drive Application
Considerations
• Monitoring Power Quality and Solving
Problems
• Using Computers to Solve Power Quality
Problems
• Developing a Power Quality Program
• Establishing Benchmarks for Utility Power
Quality Performance
• Power Quality Assurance for High Reliability
Facilities
• Building a Web-based Power Quality
Monitoring System
We also offer in-house and off-site training for the
SuperHarm®, EMTP, and PSCAD® software packages.
Our training is designed to allow you to progress at
your own speed, and consists of two or more days of
case study analysis and practical applications.
Semiannual workshops can be arranged for continuous
training.
Pricing for these seminars varies according to the
number of days for presentation, number of expected
attendees, and instructor travel costs, if any. Please
send e-mail to info[at]electrotek.com for information on
pricing, scheduling, and availability.
Full descriptions for all seminars can be found on the
Internet at www.electrotekseminars/pqtrain.htm.
Also check our web site for information on seminars
sponsored by utilities and other organizations.
Notes for selected seminars are available for purchase.

Distribution Power Quality
Electric distribution system power quality is a growing
concern. Customers require higher quality service due
to more sensitive electronic and computer-controlled
loads. Capacitor switching events and voltage sags
associated with remote faults that never caused
problems in the past now cause equipment tripping and
even failures within customer facilities. Also, customer
loads are generating increasing amounts of harmonic
currents that can be magnified on the distribution
system due to resonance conditions.
Electric utilities have addressed these concerns by
establishing programs that can help customers evaluate
problems and develop solutions. However, the solutions
are often not simple because the problems involve
interactions between the power system and the customer
electrical system and equipment.
Utility personnel dealing with distribution system
design and power quality need to develop an
understanding of how events on the distribution system
can impact customer operations. Key issues include:
• How do capacitor switching transients get
magnified in customer plants?
• How can I apply IEEE 519 to evaluate the impact
of customer loads on distribution system harmonic
levels?
• Why is customer equipment so sensitive to voltage
sags during remote faults on the power system?
• How do lightning transients get into customer
facilities?
• How do I develop a monitoring program for
determining power quality levels on my
distribution systems?
Seminar attendees will develop a basic understanding of
important distribution power quality concerns. They
will learn about the different types of power quality
problems being experienced by customers, methods for
analyzing these problems, and possible solutions. The
seminar also provides an overview of important power
quality standards.
Using Computers to Solve
Power Quality Problems
Simulation tools are a powerful way to analyze power
quality problems, and explore "what if" scenarios.
Installing a capacitor bank in the field, only to find out
that it causes major problems, can be an expensive
exercise. Simulations can determine problems before
any action is taken.
This course provide an overview of using computer
simulations to understand and study power quality
phenomena. It focuses on two different types of
computer simulation studies: harmonics and transients.
Harmonic studies are performed to evaluate resonances
caused by power factor correction banks, to compute
the additive effects of various harmonic loads, and to
perform IEEE-519 compliance calculations. This
seminar will show how harmonic loads are represented,
how power delivery systems are modeled, and how this
process is used for IEEE-519 evaluations. Example
case histories are presented showing harmonic
resonance caused by power factor correction capacitors,
the effect of phase angle cancellation using delta-wye
transformers, and the design of harmonic filters.
Transient studies are performed to study the response of
power systems to switching operations, load rejection,
power electronic modeling, and control system
dynamics. Emphasis is placed on the use of the
Electromagnetic Transients Program (EMTP), with
several case histories showing how capacitor bank
switching, breaker restriking, and power electronic
devices can be simulated.
Together, these studies provide important tools for the
power quality engineer to evaluate What happened?
What can be done about preventing it? and What is the
best solution?
