Choosing of locality, the main points of building
PSP

• Localization the part of the Nízke Tatry
  National park in the Turková National Natural
  Reservation

4
Choosing of localization, establishing milestones
of PSP

• PSP has been put into use 1981-1982
• During the period of constructing (also each of
  the operations) the following conditions had to
  be fulfilled
• - Strict governmental regulations regarding the
  environment protection
• - reducing the period of construction
• - changing of the shape of the upper reservoir
  and its inclusion in nature
• - damaging the forest vegetation
• - dissociation between construction of flats and
  social units
• - underground positioning of the conducts
• - minimum use of ground
• PSP tasks
• - keeping the quality standards when providing
  electrical energy
• - covering of the changes in the charge of the
  electric network
• - operative covering of the quick changes in the
  electric network
• - fulfilling of the regulation functions of the
  electric network

Description of the construction part of the PSP

• All the work is divided into four part
• 1, The upper reservoir
• 2, Underground conducts
• 3, The hydro power plant and the lower reservoir
• 4, Geological anomaly

6
Description of the construction part of the PSP

• The upper reservoir
• - artificial, without own the natural water
  inflow
• - bottom of the reservoir are sealed by a
  bituminous and cement coat
• - in perimeter is a tunnel for leakage water
  controlling
• - operation levels fluctuate by 25m (1.160 and
  1.135m)
• Underground conducts and the communication tunnel
• - Count of conducts 3, diameter 3,8m
• - Conducts are finished in a spherical
  distributor branching out the conduct into two
  turbines and two pumps
• - Every conduct has 3 parts a) two horizontal
  part b) inclination part with inclination 45O

7
Description of the construction part of PSP

• The hydro power plant
• - Installed power 6x111,6MW, in case of turbine
  overflow 6x122,4MW
• - Working time 5,5h
• - TG1-TG6 - 6 vertical aggregates in 3 steps 1,
  the motor-generátor
• 2, the turbine
• 3, the pump

• turbines of Francis type with internal diameter
  2600mm
• - TG7 1 turbine of the type Kaplan 0,8 MW for
  the natural flow of the river Cierny Váh
• The lower reservoir
• Made of concrete, gravitational
• lateral walls geotextile Taratex with stones
• - Total volume of the reservoir 3,7mil. M3
• - Iregularitiy of the water surface7,45m

Operating, control, and use of PSP

• Operating effectiveness of the whole cycle
  74,5
• Control accomplishing of a fully automated, PSP
  is directly controlled by production department
  in Bratislava
• Operational implementation starting from zero
  position up full power
• a, during the generator phase 70sec.
• b, during the motor phase 120sec.

13
Positioning, operation, control, use of the PSP

• Outsourcing
• - Tertiary regulations
• - Secondary regulations
• - Black start
• Dynamic functions
• - Regulation of the unexpected changes of the
  charge
• - Immediate covering of the daily charge diagram

14
Reparation of the mechanical and structural part
of the PSP

• General reparations TG
• - Re-insulation of the upper reservoir
• - Splitter (insulator)

15
Ecological aspects of PSP

• Te process of constructing
• - Cleaning of the waters coming from the machines
• - Cleaning of the waters coming from the block
  transformators
• - Changing of MTP, MTN, SF6-disconnectors
  (400kV),
• - Changing of the vacuum power disconnectors
  (22kV)
• - Removing of the compression stations
• - TG7
