THE SHPP KALJANI<br />
Selected soluti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> hydroelectric generating units<br />
for SHPP Kaljani <strong>and</strong> SHPP Cemernica:<br />
SHPP Cemernica:.......<strong>on</strong>e Pelt<strong>on</strong> unit (two runners with four nozzles)...530 kW<br />
SHPP Kaljani: ..............two cross flow <str<strong>on</strong>g>turbine</str<strong>on</strong>g>s ..................................2 x 630 kW<br />
with these hydraulic characteristics for <strong>on</strong>e <str<strong>on</strong>g>turbine</str<strong>on</strong>g>:<br />
Gross head .......... Hb = 39,50 m<br />
Net head .............. Hnet = 37,00 m<br />
Hydraulic losses ... ∑t = 2,50 m<br />
Flow rates: ... maximum flow rate at Hnet ... Qmax = 2.000 l/s<br />
minimum flow rate at Hnet Qmin = 340 l/s<br />
Guaranteed performance based <strong>on</strong> the hydraulic data in full regulati<strong>on</strong>:<br />
Flow rate 100% 90% 60% 30% 17%<br />
Output kW 630 567 378 189 107<br />
Flow rate l/s 2000 1800 1200 600 340<br />
