Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
This paper proposes a method of monitoring and analyzing interharmonics in power system based on modified covariance arithmetic and virtual instrument. The system consists of sensors, signal conditioning circuits, transfer boards, data acquisition (DAQ) and compute, which the parameters of interharmonics are identified by using the modified covariance arithmetic of AR model, Some essential issues,...
