Research and Development of Efficiency-Measuring Meter for Multi-Functional Hydropower Unit

In order to extend and disseminate the efficiency-measuring meter for multi-functional turbine power units, the structures, functions, and the efficiency test data analysis software of the device are introduced, and the precision and error analyses of numerical integral are also discussed in this paper. This kind of meter can be used in the axial-flow turbine and mixed-flow turbine velocity tests, as well as the real-time data collection and processing for the efficiency test and velocity test of the unit prototype of spiral case pressure-difference method. The actual test data show that the device can work reliably with high test precision, data processing accuracy and efficiency.
