Comparative Analysis of Orifice Area and Differential Pressure along a Penstock of Hydro Turbine
Abstract
The study, comparative analysis of orifice area and differential pressure along a penstock of hydro turbine was successfully investigated using data gotten from simulink simulation of System block models from simscap- hydraulics. 5 variable orifice areas, 0.1m^2, 0.04m^2, 0.15m^2, 1.5m^2 and 0.0002m^2 and their corresponding differential pressures were analyzed and graphs plotted, using Excel and MATLAB. At orifice area of 0.1m^2 , differential pressure was found to be 150bar. As orifice area was reduced to 0.0002m^2 , differential pressure increased to 30,000,000bar. These results suggested that narrowing or decreasing hydraulic orifice area, will increase differential pressure along the penstock of a hydro turbine and vice-versa. In addition, MATLAB was used to evaluate the variance and standard deviation between the orifice area and differential pressure data. The variance was found to be 2.1493e-07 while standard deviation was found to be 4.6361e-04. The researchers made the following recommendations: Influences of hydraulic orifice area and differential pressure have to be controlled if hydro turbine must operate at full power, this research can also be done in future using different hydraulic design orifice models and other advanced software for generalization.
