GovHydroPID2
Hydro turbine and governor. Represents plants with straightforward penstock configurations and 'three term' electro-hydraulic governors (i.e. WoodwardTM electronic). [Footnote: Woodward electronic governors are an example of suitable products available commercially. This information is given for the convenience of users of this document and does not constitute an endorsement by IEC of these products.]
