Abstract :
Energy consumption in pumping systems is affected by the surrounding process. As frequency converters allow sensorless estimation of the pump operating state, they can also be used for the process characteristics identification. In this paper, two frequency-converter-based methods to identify process characteristics are proposed, and the start-up test method is more closely studied by laboratory tests.
