General overhaul in PSPP Avče is in full swing
General overhaul is going to be completed in the middle of May 2019 by implementation of trial run and control measurements.
On 5 November 2018, Rudis as sub-contractor of servicer HM Hydro, Japan, began with works of general overhaul of turbine and generator in pumped-storage hydropower plant – PSPP Avče on the Soča River.
PSPP is the only pumping power plant in Slovenia and it started operating in 2010.
With its 185 MW, power plan annually generates 426 GWh of electrical energy
Disassembly of equipment is currently is in progress. We have already executed the complete disassembly of generator by pulling out 280 tonnes rotor. We have already also executed the most demanding phase of disassembly, i.e. lifting half of turbine cover through stator of generator. One half weighs 24 tonnes, gap between cover and stator is less than 100mm!
During the overhaul, measures that are going to contribute to increased safety and reliability of power plant's operation are being implemented.
