Lab-Volt's 8010-E
Power Transmission Smart Grid Technologies Training Systems
allows teaching of 3-phase AC power circuits and transformer banks,
AC transmission lines, high voltage DC transmission systems,
static var compensators, and static synchronous compensators.
The students will first learn 3-phase AC power circuits
using a fully variable 3-phase power supply
along with 3-phase resistive loads, capacitive loads, and inductive loads.
This will allow them to see 3-phase circuits,
three-phase power measurement and phase sequence.
When the versatile quadrant dynamometer power supply
is used as a power supply, it can act has a DC voltage source
up to 150 volts positive or negative
and can also be used as a current source
positive or negative up to almost five amps. Please note that this power supply
is reversible, meaning that it can both supply power as well as sink power.
It can also be used as a variable voltage 50 Hertz source
or as a 60 Hertz source.
To get measurements that are easy to understand and to connect,
we use a data acquisition and control interface,
which has 4 voltage inputs as well as 4 current inputs.
The data acquisition unit helps the students understand the important concepts
of phase shift, reactive power, and power factor in AC circuits
by using powerful instruments such as phase angle meters,
active, reactive and apparent power meter,
and a power factor meter. It can also use a fasor analyzer, which allows you to see
what happens when you change the nature of the loads.
A powerful oscilloscope that can display up to 8 traces of voltages, currents, or
instantaneous power also really helps the students understand these concepts.
Instead of using precious lab time to copy data,
the students can use the automated data tableto create graphics
that will be easy to understand and save them time to further understand the theory needed
for these labs.
3-phase transformer configurations,
such as delta to delta, y to y, y to delta, and delta to y,
will then be studied. The students will then see AC transmission lines
learning voltage regulation characteristics,
voltage compensation, power transmission capacity,
voltage compensation in long AC transmission lines,
and control of active and reactive power flow. The data acquisition and control
interface will also be used to control power thyristors,
allowing the study of high-voltage DC transmission systems.
The students will see topics such as voltage regulation
and displacement power factor in fthyristor 3-phase bridges.
Basic operation of high-voltage DC transmission systems,
DC current regulation and power flow control in high-voltage DC transmission systems,
commutation failure at the inverter end, and harmonic reduction using
thyristor 12-pulse converter.
The students will then go to static var compensators,
seeing the main components of a static var compensator,
voltage compensation of AC transmission lines using SVCs,
and power factor correction using as SVCs for example on hard furnaces.
The last topic of the system
is static synchronous compensator, or STATCOM.
Students will learn voltage compensation using a STATCOM
and power factor correction using the same technology.
The modularity of the system makes it very easy to add
or remove topics to fit your program better. For example you could
easily add motor drives, power electronics,
home energy production, basic DC and AC circuits,
wind turbine generators, hydro electricity generators,
and many other topics.
The full color books include both theory and practical exercises that will help
the students understand all of the necessary topics.
In summary Lab-Volt Power Transmission Smart Grid Technology Training System
is flexible and has the power to teach all the necessary topics
for an advanced world.
