| Summary: | At the large industrial enterprise which contains
several types of technological lines for maintenance of
continuous production process in a power grid complex
of the metallurgical enterprise (ME) for realization of
a normal mode of the power system operation it is
necessary to provide quality of power supply which is
defined by reliability and profitability. For evaluation
of reliability and condition of electric grid complex
it is required to perform analysis of disturbances in
operation modes of power supply system of SE with
voltage of 10–220 kV during 2007–2020 years. The
analysis of the static data of outages showed that
the main reasons of power supply failure are short
circuits, imposing of several factors and unexplained
circumstances, and 70 % of all failures are in cable
lines, 25 % — overhead lines and 5 % — failures
of power transformers. At present, the connection
between electrical equipment and the technological
objects being fed depends on their wear and tear. On the example, the main technological processes of
ferrous metallurgy production are considered sintering
and rolling production, as the most energy-intensive
and responsible consumers. It is necessary to identify
categories of the most worn-out electrical equipment
to develop a set of measures to improve reliability and
reduce damages. |
