Abstract
This paper presents a home area network (HAN)-based domestic load energy consumption monitoring prototype device as part of an advanced metering system (AMS). This device can be placed on individual loads or configured to measure several loads as a whole. The wireless communication infrastructure is supported on IEEE 805.12.04 radios that run a ZigBee stack. Data acquisition concerning load energy transit is processed in real time and the main electrical parameters are then transmitted through a RF link to a wireless terminal unit, which works as a data logger and as a human-machine interface. Voltage and current sensing are implemented using Hall effect principle-based transducers, while C code is developed on two 16/32-bit microcontroller units (MCUs). The main features and design options are then thoroughly discussed. The main contribution of this paper is that the proposed metering system measures the reactive energy component through the Hilbert transform for low cost measuring device systems.
Highlights
Growing concern about energy consumption is promoting the better usage of energy resources at different levels of human activities
Different strategies are being planned toward transformation of the classical electric network into smart grids [6], and tariff schemes based on demand response programs that call for a paradigm shift in terms of domestic energy consumption habits [7], or by technological interventions at the level of alternative control techniques for reducing electric energy consumption in the normal usage of domestic appliances [8]
Its architecture meets well the needs of wireless applications with moderate data processing demands that can be performed by the internal microcontroller units (MCUs), while at the same time providing a compact solution enabling robust and flexible operation for networking configuration, operation and maintenance due to mesh networking capabilities offered by the ZigBee protocol
