Flow metering system at the Plyavinyas hydroelectric station

Conclusions1.When computing the average daily discharges through hydraulic turbines, using their operating characteristics, systematic errors can arise, caused by the use of imperfect methods of determining the mean loads and heads. The large volume of effort involved in a detailed computation of flow can be avoided by introducing correction factors into the simplified equations used, whose values can be determined by making a detailed analysis of the available flow-estimating data.2.A substantial increase in the accuracy of the flow estimates at a hydroelectric station is achieved by fullscale tests made to determine the operating characteristics of hydraulic turbines and spillways.
