Overhead and underground power line monitoring is an essential infrastructure for advanced operation in the smart grid. Wireless sensor networks are attractive to remote power line monitoring, due to their rare geography restrictions, simple engineering design, and flexible equipment expansion. Considering the ZigBee’s characteristic of low transmission rate, almost commercial sensors adopt the high-speed...
Based upon the analysis of load signatures, this paper presents a Non-intrusive load monitoring (NILM) technique. With characterizing associated with the transient response of energy signature, a reliable and accurate recognition result can be obtained. In this study, artificial neural networks (ANN), in combination with turn-on transient energy analysis, are used to improve recognition accuracy and...
This study combines coreless Hall effect current transformers (HCTs), ZigBee communication, and a quiescent voltage adjustment to develops a new current measurement method for non-straight conducting wires. The proposed design includes the unique characteristics of low cost, low power consumption, and wireless communication capability that makes it flexible for current measurement at different environments...
