This book examines modern methods of creating models and measures
in measurements, physical and probabilistic measures, models,
spaces and bases of signals and fields, deterministic and
probabilistic models and measures of angular quantities. Examples
of their use on a circle and in phase measurements are given;
models and measures for diagnostics in the electric power industry,
in standardless measurements of the characteristics of composite
materials, in environmental pollution monitoring systems, also with
using unmanned aerial vehicles, are considered. Most of the
presented results were obtained on the basis of the Institute of
Engineering Thermophysics of National Academy of Sciences of
Ukraine. The book is intended for researchers, engineers, as well
as lecturers, graduate students and students of higher educational
institutions dealing with the problems of measurements, monitoring
and diagnostics of complex technical objects.
This book is devoted to the development of complex methods and
means of their implementation with using UAVs aimed for improving
the safety and efficiency of the energy system. The scientific
problem of complex automated monitoring of the energy system
objects with using UAVs has been solved, including the control of
its elements in the visible and infrared range, the acoustic
spectrum, as well as by the levels of the electric field strength.
The scientific foundations of mathematical, physical and
statistical modeling of electromagnetic and acoustic fields in the
elements of electric power objects of complex spatial
configurations have been created, taking into account the
possibility of the appearance of such nonlinear processes as corona
discharges and breakdowns at long air gaps. Improved methods are
proposed for determining the exact location of accidents on power
lines using UAVs on the basis of the developed mathematical models
and the obtained analytical expressions. Conceptual foundations for
the creation of methods and means for monitoring the state of
insulation, lightning protection systems and the integrity of the
structures of electric power facilities with using UAVs have been
formed.

This book examines key issues in improving the efficiency of small
and medium power boiler units by adding control systems for the
fuel combustion process. The original models, algorithms, software
and hardware of the system developed for controlling the fuel
combustion process are presented. In turn, the book presents a
methodology for assessing the influence of climatic factors on the
combustion process, and proposes new methods for measuring the
thermophysical characteristics, which require taking into account
the concentration of oxygen in the air. The system developed here
was implemented on a boiler of the NIISTU-5 type, which is widely
used for heat power engineering in Ukraine and other Eastern
European countries. Given its scope, the book offers a valuable
asset for researchers and engineers, as well as lecturers and
graduate students at higher education institutions dealing with
heat engineering equipment.
This book examines key issues in ensuring the operational
reliability of energy facilities. In this regard, it analyzes
mathematical models of diagnostic signals that arise during the
operation of power equipment; reviews the main findings of research
into their characteristics; presents diagnostics methods for
selected types of electric power and heat engineering equipment;
and covers a range of diagnostic and monitoring systems and devices
for power equipment. Given its scope, the book offers a valuable
resource for researchers, engineers and specialists, as well as
instructors and graduate students at institutions of higher
learning.
