Original abstract
The paper is concerned with the potential occurrence of head and flow oscillations in a long water feeding pipeline of a hydraulic power plant. A situation is analysed which is characterized by oscillations being caused by two conditions occurring simultaneously – the water feeding pipeline of a controlled hydraulic power plant is prone to resonance and the controlling system generates undesired changes in the turbine opening at exactly the critical frequency.

Příspěvek ze zabývá problematikou možného vzniku oscilací tlaku a průtoku v dlouhém přiváděcím potrubí při provozu vodních elektráren. Je analyzována situace, kdy oscilace vzniknou současným výskytem dvou nepříznivých okolnostií – regulovaná soustava s vodní turbínou a přivaděcím potrubím má sklon k rezonanci a řídicí systém generuje nežádoucí změny otevření turbíny právě s kritickou frekvencí.
