The destribution system operators have to do a plan of network development for theirs own
operated (and in theirs operation authorization fixed) distribution system. This medium and
long term plan what has built on the technical-economical condition system - to cooperation
with the transmission system operator-, provide the continually and safe electric power
Nowadays in our state, the Budapesti Elektromos Művek (ELMŰ) Nyrt. serves out the greatest
load as a destribution system operator. For the supplying area of the central of Pest has no
any detailed, long term plan yet. As a distribution system there is only the 10 kV network.
The most busy part is the city center of Pest, where the structure of the network is still very
complicated without any concerted development action. For this reason the system’s review
and form is necessary now.
As a part of the modernisation and development plan for the city center of Pest, this thesis
main point to assessment and document the current state of the 10 kV cable network. Discovering
the system’s main deficiencies hereby to define the planning’s main directive of the
engineering design. The problem is unusual because of assessmenting a part of a connected
network defined by a located area. The investigation method was materialised by two main
aspects. To emphasize the system’s configuration and operation.
