Experience Measurement of Winter-Kennedy method on low head tubular turbine units

Abstract

With large development of renewable energy, especially the low head hydraulic power stations, specifications of the turbines have been got more and more attentions. The discharge, which is one of the most important parameters relative to unit performances, is difficult to be determined according to the passage layout. In this paper, applying "Winter-Kennedy" measurement method though modification and comparison with test and simulation, characteristics and coefficients of turbine units, derived from different pressure at certain locations, are calibrated and established. After further verification, it will of great help to confirm the relationship of unit output, water head and hydraulic efficiency, as well as optimal dispatching and stable operation of hydropower stations.
