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)
