Power calculation error propagation correction using linear regression factors in a distributed WSN for household devices

Abstract:

This paper describes the use of a linear-regression algorithm to correct errors propagated through a Wireless Power Measurement System for low voltage household devices. The algorithm is a fundamental part of a WSN used to collect time-stamped power measurements from household devices. The chosen algorithm allows to correct errors arising from the intrinsic characteristics of current and voltage sensors, ADC hardware delays, and processing delays. Implementation results demonstrate the use of this algorithm allows the use of low-cost sensors without sacrifying precision and accuracy.
