Technique for Improving the Flow Rate Estimation Range by Using an Axial Flow Water Turbine Generator

Abstract

This article presents a technique for improving the flow rate estimation range in an axial-flow water turbine generator, which is used as a substitute for the flow rate control valve in an air conditioning control system. This article also presents a flow rate estimation technique that uses the characteristic function of the axial-flow water turbine generator based on the angular speed, the torque, and the pitch angle of guide vane. The effectiveness of the proposed technique is validated by experiments.
