OEEABed-Online Distributed Energy Efficiency Analysis Testbed and Novel Monitoring Approach under Wireless Sensor Network

Abstract

Energy efficiency analysis system need to be widely deployed to collect energy consumption data in a timely schedule and also the online monitoring integrated with dynamic analysis. Smart metering system have similar functions and can be used with some equipment reformation, but the now exist system can not be used in a plug-and-play manner, which is the main constraint on large scale deployment. In this paper, a novel distributed measuring approach is proposed with only one modification of the incoming line to monitoring the bus voltage. While other sensor nodes that deployed at several monitor point are designed with integrated communication and measurement component, which can be used online without blackout or power line interruption. Standard IEEE 802.15.4 beacon frame payload is extended on the concentrator side, and thus the zero position sequence (ZPS) and selected full sampling in one period is conveyed in the extended frame to assist each distributed measurement and synchronization. To verified the feasibility of the proposed distributed measurement by using wireless sensor network, we established online energy efficiency analysis testbed (OEEABed), experimental results are presented to illustrate the effect of both network performance and signal processing parameters.
