 Automation
Automation is the use of control systems to control
industrial machinery and processes. Our laboratory
starts from the study of PLCs to allow students the
analysis and the acquisition of the techniques related to
programming a PLC and to its use in control technology.

The laboratory then includes a set of real situations

simulation panels to facilitate, in a user-friendly and
stimulating way, the study and the programming of the
PLC: programmable traffic lights, automated parking
Process control garage, three-floor elevator, etc.

Our proposal continues with the study of the control

of alternate and direct current motors and with the application of the PLC programming techniques to processes
where to control level, pressure, temperature and flow of a typical industrial process plant.

The laboratory is, then, completed with a pneumatic and electro-pneumatic trainer and with a modular system
representative of the automation techniques for industrial production (CIM, Computer Integrated Manufacturing),
a very topical subject, the latter, basis for modern industry.

fundamentals of automatic control technology. The
main functions of processes, controllers and controlled
systems are shown on a simulated controlled system, as
well as the interactions between the transfer elements
of a control loop.

 Smart Grid

The Smart Grid is a system for the “intelligent

distribution” of the electric energy, able to compute
the energy consumptions of the different end users
and to manage the generation and the electric
energy as a function of the demand.
Therefore, it has the task of sharing the electricity
generated by different sources, both public
and private, traditional and renewable, and of
guaranteeing that the electric devices use the
electricity in the most efficient way.

The didactic laboratory for the study of the concepts related to the Smart Grid system proposed by De Lorenzo
is composed of a set of equipment and modules and of a SCADA type software that allow performing practical
experiences on the techniques of generation, transmission, protection and utilization of electric energy in a new
generation “intelligent” network.

The laboratory considers the simulation of the generation of energy from three different sources:

• a traditional energy (coal, gas or other sources)

• a hydroelectric source
• a wind energy source

The transmission and the distribution of electric energy are reproduced through the simulation of high voltage
lines and step-down transformers for the transmission voltage.
In the section relevant to the utilization of the electric energy there are resistive, inductive and capacitive loads
and systems for the generation of photovoltaic solar energy with grid type inverter for the injection of the excess
energy generated by the photovoltaic panels.
Line protection relays and instruments for data acquisition are placed in suitable spots of the system. A SCADA
type software provides to the acquisition of the data coming from the measurement instruments and to the
control of the actuators in order to perform an intelligent management of the whole electric system.

 Electric Measurements

The laboratory for the study of the electric measurements

is composed of a set of real instruments and components
mounted on isolated panels, that, in turn, can be
assembled on a work frame to allow performing the
electric connections and carrying out all the experiences
described in the didactic manual in a simple and effective
way from the learning point of view.

 Work Benches for Electric Installations

Two place work

bench with 2
independent
supplies

Four place work bench

with 4 independent
supplies

The main feature of these work benches is their high flexibility and autonomy; they do not need a main distribution
control panel, but just a cable to supply them the mains voltage.

Designed to allow the performance of wiring experiments in the area of civil and industrial installations, they offer
the maximum work versatility in the laboratory. Thanks to the fast hook-up system for the panels on which the
student makes his circuit, it is possible to store all the works that have not been completed in a single lesson and
leave the frame free for other students.

The supporting structure is made of tubular, fire varnished and rustproof steel, while a large bi-laminated wooden
surface can be used for tools and wiring accessories. Furthermore, the workbench is provided with compensator
feet to offset unevenness of the floor. The power supplies are provided by means of a vertical module placed by the
side of the work panels and all the supplies are protected according to current regulations.

On request, it is possible to add to the bench a series of accessories, such as: drawers, chest of drawers, central
cabinets, socket-holders, work panels and containers to house the panels.

 Home Automation
Home Automation deals with technologies, devices and systems that
provide, in a house or, more generally, in public and private buildings,
increased quality of life and safety, energy saving, lower installation
and maintenance costs for the electrical devices and simplified
maintenance for the electrical system.
The system that we propose needs just a single bipolar conductor
through which all the end users connected to the “bus line”
communicate among them.
The products are compatible and interoperating among them, even
if they come from different manufacturers. The system is then
controlled and managed by a software package, through which the
single components, all connected in parallel to the single bipolar line,
gain their “individuality” through an identification address and are
programmed for the type of function and for the system where they are installed.
The study subjects include the following categories: lighting systems, shutter control systems, safety systems and
heating/air conditioning systems.
For all the above categories the manuals include practical exercises by using standard components. Each experiment
describes step by step the design, the configuration and the commissioning of the system.

In detail, the modules that we propose for the Home Automation laboratory are the following:

Single phase power unit Bus power supply Push-button interface

26
The modules can be grouped in a set of standard configurations for the study of specific subjects, such as, for
instance:
• Lighting
• Shutter control
• Safety
• Heating
• Scenery module
• Monitoring and Control

It is also possible to use a PLC for the control of the modules.

It is then necessary to add to the above mentioned modules a
work frame with 2 or 3 levels, according to the number of modules
forming the selected configuration, and a set of connecting leads.

 Power Electronics

The objective of power electronics is the control of the power

flow through the conversion of the mains voltages by means
of power semiconductors able to perform the functions of
switching, control and conversion of electric energy in an
efficient and reliable way.

electronics that provides to the student a practical learning
based on the performance of guided exercises.

The study subjects include the following categories:

• AC/DC conversion • DC motors drives
• AC/AC Conversion • AC slip ring motors drives
• DC/DC conversion • AC squirrel cage motors drives

 Electrical Power Engineering

The Electrical Power Engineering laboratory deals

in a complete and systematic way the subject of
the electric energy cycle, from its generation to
its transmission and distribution over high voltage
lines, with relevant protection relays, and its
utilization by the end users.

Therefore, the laboratory is divided in four main sections:

• Energy generation, where we study a bipolar alternator driven by a dc motor and different synchronization
circuits.

• Energy transmission and distribution, where we analyze a three-winding transformer and a line model to
study its characteristics at different load conditions.

• Protection techniques, where we study the measurement transformers and the relays that are most frequently
used for the protection of the lines.

• Energy utilization, where we discuss the problems relevant to the compensation of the reactive energy and
the methods with the devices needed for the measurement of the electric energy in alternate current and in
three-phase networks.

The laboratory is modular and includes more than 60 elements, panel type and bench type, that can be purchased
also gradually, starting from the most interesting subjects, to reach the integration of the full laboratory at a later
time.

 Autotronics
Hybrid and electric systems
Electronic technology has strongly entered the
automotive field and is currently influencing the
main characteristics of the people working for the
maintenance and the improvement of the vehicle
operation.

New systems for air conditioning, ABS braking,

antitheft devices and others have been regularly
added to the traditional electrical systems for
lighting, power and ignition/injection.

To fulfill the training needs of the automotive industry, DE LORENZO has realized a multidisciplinary laboratory
that allows the theoretical study and the practical analysis of the problems related to the field of electrical and
electronic technology applied to automobiles.

The laboratory consists of a set of simulation panels for the study of the electrical and electronic systems and sub-
systems that are used in modern motor vehicles and of a set of demonstration trainers with real components for
a more direct and practical approach to the automotive subject.

The simulators are provided with a CAI (Computer Assisted Instruction) software and can be connected in a local
network with a control software for the teacher. The possibility to insert simulated faults increases the flexibility of
these didactic systems and make them well suited for training a modern engine mechanic.

 Oil & Gas and Industrial Chemistry
Water treatment
The chemical energy is a manifestation of energy. In
particular, it is an aspect of the internal energy of a body:
even if it is always present in the matter, it manifests itself
only when there is an alteration in the matter itself.
Chemical energy is the one that moves cars, ships and
planes and, in general, millions and millions of machines.
Both the combustion of coal, wood or oil in steam machines
and the combustion of petroleum derivatives in the narrow
space of the cylinders of an internal combustion engine are
chemical reactions.

Mankind has always used the chemical reactions to produce energy, from the most rudimentary, such as burning
of wood or coal, to the most sophisticated, which occur in the engines of modern aircraft or spacecraft.

In our laboratory, we study the basic processes, such as absorption, desorption, adsorption, liquid-liquid and solid-
liquid extractions, chemical reactions, etc., water treatment and gas treatment.

Particular attention is paid to the equipment and chemical processes used in the petroleum industry, particularly
those that are most commonly used in refineries for processing crude oil into finished products.

PH control

Chemical reactions Absorption-Desorption

40
The laboratory of chemical and petrochemical engineering is also involved in studying the types of equipment
that find within a refinery a distributed and intensive use, such as compressors, various types of pumps, fans, heat
exchangers, etc.

Finally, a topic of particular interest in the oil industry, but not only, is the study of the phenomenon of corrosion
of metal structures and of the methods to combat it. In particular, in the laboratory we can test the techniques for
the prevention of the corrosion by the method of the cathodic protection, both of the type with sacrificial anodes
and of the impressed current.
