Most likely first implementation
Brazil – Itaipu power plant
ABB – Excitation system
Alstom – Turbine governors
Logical nodes that might be added:
HTUR – the turbine (maybe different for Francis, Kaplan and Pelton)HEXT – Excitation system basic information HGVR – Turbine governor basic information
HDTG – Draft tube gateHIVV – Inlet valve (valve at the lower end of penstock)HPST – PenstockHSSL – Shaft sealingHSUD – Surge shaft, downstream sideHSUU – Surge shaft, upstream sideHTRT – Tail-race tunnelHWGT – Guide vanes (wicket gate)
