In this paper the main focus is on the turbogenerator and positive changes in it. There is
replacement the active steel end zone of the turbo-generator n.1 which operates in REK Bitola, with
purpose to improve the condition of the turbo-generator from magnetic point of view during the
modernization for increasing the power. Turbo-generator is type TVV 200-2A produced by
“Elektrosila” – Russia. The stator winding is cooled directly with distilate. The rotor winding, the
stator core and the housing are cooled with hydrogen.
The reconstruction itself covers replacing more elements which are: Replacement of five
end packs of each active steel end zone, which are manufactured in monolithic (backed) version and
with successive reducing of its height. Reconstruction of the pressure rings with simultaneous
installation of new enlarged copper screen on the pressure rings. Additional fingers for better
tightness and intensifying the cooling of the end zones.Stabilization of the pressing tightness of
turbo-generator core active steel with installing special spring devices so called pressure
During the realization of the reconstruction special tools, devices and equipment have been used.
Also for all examination which has been done protocols (test reports) have been made. Every test
report consist from: test object, basis, and criteria of control, test results and conclusion on the test
Keywords: Turbogenerator, replacement, end packs
