Power Measurement and Data Logger Device with High-Resolution for Industrial DC-Grid Application

Abstract

Abstract – power and energy measurement and monitoring is a key leading factor for many industries in terms of energy and cost efficiency evaluation. Due to trends of Smart Grid concept application in industrial environment, including decentralized DC-Grid implementation, for precise evaluation - faster and lower cost measurement equipment is needed. Manufacturing industry use lot of industrial robots that have dynamic load characteristics, and to know their consumption faster measurement equipment is needed.

This paper gives brief description of developed power measurement equipment, its structure and interconnection to industrial PROFInet network. Further as a testing method steady state and dynamic loads are selected and analyzed. For testing, specially created industrial DC-Grid testing environment and equipment has been used. Testing results shows that selected method and idea is working, and it is able to measure dynamic loads with high resolution. For other industrial load types, discussion rises, about how detailed resolution is needed in industrial SmartGrids, as energy forecast is a new trend in robotic industry, and manufacturing planning.
