Analysis of electrical power data streams in manufacturing

Abstract

In-process monitoring of the electrical power of manufacturing equipment has become technologically and economically viable and is essential in capturing the energy consumption behaviour of manufacturing systems in relation to operations. A concept for real-time analysis of electrical power, based on data stream analysis and event-driven system approaches has been developed and implemented as a software application. Electrical power data is handled in the form of streaming time series and are statistically analysed and transformed in compact, information rich representations in real-time. The developed prototype is validated on the example of a milling machine.
