MATHEMATICAL MODELLING OF HYDRAULIC TRANSIENTS IN POWER CHANNELS

Abstract

Surge waves are developed in power channels due to load acceptance, load reduction and load rejection by the power stations which is a frequent phenomenon in the hydropower plants because of being generally peaking stations. - Computations forthese transient-states, developed due tofrequent operation_ of wicket gates and head regulator, is frought with complexities, therefore; not common._x000D_ That is why till now design of hydropower channels -are done assuming-the steady state flow conditions, and for transient-state condition surge tank is provided to dampen the transients. But in small, mini or micro power plants surge . tank is avoided due to. cost consideration and for transient-state condition a byepass channel is provided and operated to release -the rejected discharge. In this case during each rejection period a huge amount of water power potential is being wasted....
