Abstract. The article is devoted to the research and implementation of modern
telecommunication technologies electrical of engineering complexes in the
electrical industry in order to increase their reliability. It analyzes the latest
technical developments in the field of automation, such as information technol-
ogy, communication technology, etc. The following methods are used: induc-
tion and deduction analysis and synthesis, statistical modeling. As a result of re-
search on the basis of modern automation systems, an energy-efficient micro-
processor automation system has been developed to control the operating mode
of complete transformer substations with a voltage of 6-10/0.4 kV, which serves
to create servers for real-time control systems for electrical consumers. When
creating Automated control systems for the energy sector of an enterprise, it is
possible from the information management system - IMS, for example, from the
enterprise’s mini-computer at the enterprise’s dispatcher station; har-monics in
the voltage curve, as well as other necessary information.

1 Introduction
A distinctive feature of the modern stage of development of society is the increasing
contribution of information and communication technologies to accelerating the de-
velopment of science, technology, economy, social sphere and various industries. In
recent years, in world practice, the most general principle for the development of
management systems at various levels (from national-scale management systems to

corporate and individual enterprise management systems) is the focus on the creation
and use of a single information and communication space state (SICS) [1-8].
The transition, which has begun abroad, to servers of real-time control systems
(SCADA) and the next generation of digital relay protection and automation devices
(DRPA) with integration within a single information complex of functions of relay
protection, measurement and commercial metering of energy efficiency, regulation
and control of an electrical installation [8-10] is aimed at improving the reliability of
power supply to consumers. Often, protection terminals perform the function of
lower-level controllers.
2 Materials and methods
ACS (Automated control systems), providing comprehensive protection of substation
control at a modern level. In this case, they provide control on site or from remote
dispatching points (DP), control of the position of primary equipment, measurements,
signaling, recording and transmission of oscillograms. In addition, the ACS allows the
user to record / change settings using a password, receive reports and keep an archive
of events, monitor the status of primary equipment, etc. [9]. In a generalized form, the
evolution of technologies (for the considered class of systems) can be illustrated by
the data given in [4-7].
Fast Ethernet, Gigabit Ethernet and 10G Ethernet are used as high-speed backbones
capable of supporting high volume traffic. Comparison of these standards RS-232 and
RS-485 is given in [4-7; 10].
3 Results and Discussion
Numerous technical implementations of modems from different manufacturers, rep-
resenting some generalized structure of a modern intelligent modem, are shown in
Figure 1 [6].

Local Area Networks of the IEEE 802 Committee. Local area networks, standard-
ized by the Committee of 802 of the Institute of Electrical and Electronics Engineers
(IEEE), are a family of local area networks, built on the basis of datagram data trans-
mission technologies. Such networks are based on Ethernet networks built on separate
standard technologies, such as IEEE 802.3, IEEE 802.3u, etc., although other net-
works standardized by the IEEE 802 committee are used [2-10].
WLANs are mainly used in concatenated LANs, where high-speed Ethernet net-
works are the backbone, such as in the APCS of oil and gas industry. An example of
such a network is shown in Figures 2 and 3.

Classification of wireless networks of the IEEE 802 committee and their possibili-
ties are shown in Figure 4.
It is clear that wireless communication lines are used where it is impossible or im-
practical to establish wired or fiber-optic communication lines.
Wide use of servers of real-time control systems (SCADA) in electrical installa-
tions of consumers provides [6-9]:
─ reception / transmission of television information in any protocols;
─ reception / transmission of data from the daily dispatch list (DDL);
─ processing of incoming information, formation of a real-time database (RTDB),
archiving;
─ control of the control room (digital instruments, symbols, mnemonic diagrams,
information boards);
─ cyclic copying of RTDB to file servers of the local network (LAN), etc.

The TMS elements considered above are implemented in the OT-A3-12 applied
project “Development of an energy-efficient microprocessor-based system for auto-
mating the control of the operating mode of complete transformer substations with a
voltage of 6-10 / 0.4 kV”. The ongoing scientific applied project relates to the study
of automation of complete transformer substations with a voltage of 6-10 / 0.4 kV.
Currently, research has been carried out and continues in this area, various circuit
solutions have been developed.
The introduction of the communication Bus COM module into the automation sys-
tem, which serves as an additional function of data transmission, implemented in the
sectional input cells from the transformer and from the Masterpact NT backup source
AB, allows to provide, when creating an ASUEnergo enterprise, the possibility of a
top-level information and control system, for example, from a mini-computer of the
dispatching office of the enterprise, control (either through a PLC or bypassing it)
installed on the supplying substation AB, transfer to the upper level data of measure-
ment, alarm, automation, registration, monitoring of harmonics in the voltage curve,
as well as other necessary information , for example, the state of AV switches in vari-
ous connections of the KATP, the presence of voltage at the inputs and sections of the
KATP buses. Thus, the functional capabilities are expanded, the reliability and per-
formance of the KATP are increased.
The main elements in the laboratory installation of the developed automation sys-
tem for controlling the operating mode of complete transformer substations with a
voltage of 6-10 / 0.4 kV are: ARDUINO UNO microcontroller; TONGLING JQC-
3FF-S-Z relay module with technical characteristics - 5 VDC, 10A 250 VAC, 15A
125 VAC, 10A 250 VAC; Relay 12 V DC Omron MY4N-j; Relay 220 V AC Omron
MY4N-j; Power supply 5 V DC AC adapter), model XC 313 with a voltage of 5 V at
a current of up to 2 A; Power supply 12 V DC RS-300/120-S325 12V / 3A (analogs:
AD PV16, P30B-3P2J); Signal lamps ART AD 16-220 D / S31 AC 220 V 20 mA.
The diagram of the laboratory installation of the developed automation system is
shown below in Figure 5.
To be able to control power consumption, manage power consumption, accumulate
information about the loads of the busbar sections of the STC, integrate the Master-
pact NT H1 circuit breaker into the dispatching system, an additional communication
bus function COM is used [9], implemented in the sectional input cells from the trans-
former and from a backup source, AB Masterpact NT. For these withdrawable units,
an additional data transfer function is provided by:
─ communication module installed in the device, supplied with a group of sensors
(microcontacts OF, SDE, PF, CH) and a set of communication with XF and MX
control electromagnets;
─ communication module, installed in the chassis, supplied with the group of sensors
(contacts CE, CD, CT).
Each installed unit has an address that can be assigned to it using the Micrologic
control unit keypad (Modbus) or remotely (Batibus).

4 Conclusion
Thus, according to the results of the study, the following conclusions can be drawn:
─ The analysis made it possible to identify promising information technologies that
largely determine the appearance new generation control systems;
─ It has been determined that the created mathematical model of the functioning of a
telecommunication system in a complex interference environment and conditions
of exposure to damaging factors is a theoretical basis for substantiating require-
ments in the design of networks and communication systems special and dual-use;
─ RU-0.4 kV STC equipped with a PLC, providing comprehensive protection of
substation control at a modern level, can perform the function of the lower level of
ASU energy. In this case, they provide automatic control on site or from remote
control rooms, monitoring the position of primary equipment, measurements, sig-
naling, recording and transmission of oscillograms, etc;
─ In the development of the theory and improvement of the methodology for the
design of power supply systems for industrial enterprises, an important place is
taken into account in such developments of the currently existing consumers in
electrical installations and the modern servers of real-time control systems
(SCADA), microprocessor-based registration systems being introduced into opera-
tion practice emergency events, collection and processing of data on the operation
of relay protection and automation; communication systems of new complexes
with the computer "core" of the integrated monitoring and control system, as well
as information display systems at the workplaces of operating personnel and per-
sonnel of relay protection and automation services;
─ Thus, when creating an ASUEnergo enterprise, it is possible from the I&C of the
upper level, for example, from the mini-computer DP of the enterprise, to control
(either through the PLC, or bypassing it) the automatic switches (AB) installed on
the supplying substation, transfer to the upper level measurement data, alarm,
automation, registration, monitoring of harmonics in the voltage curve, as well as
other necessary information, for example, the state of AV in various connections of
the KTP, the presence of voltage at the inputs and sections of the buses of the KTP,
etc.
