Apparatus for automatically controlling the active power produced by the generator of a hydraulic turbine-generator unit
Patent
·
OSTI ID:5984165
An apparatus is disclosed fortomatically controlling the active power produced by the generator of a hydraulic turbine-generator unit, comprising a frequency-responsive summing means having its inputs respectively connected to a reference signal source which develops an assigned power signal, to a power measuring means responsive to the active power produced by the generator, and to a gate opening sensing means responsive to the degree of opening of the hydraulic turbine gate apparatus, and its output connected to a control means for controlling the degree of opening of the gate apparatus. The frequency-responsive summing means is adapted to develop at its output a signal representative of an algebraic sum of the signal applied to its input connected to the reference signal source, the low-frequency components of the signal applied to its input connected to the power measuring means and the highfrequency components of the signal applied to its input connected to the gate opening sensing means.
