TL;DR: In this article, the transmission procedure uses the power distribution network (7) for data transmission between a source station and a number of subscriber stations, using modulation of a carrier frequency.
Abstract: The transmission procedure uses the power distribution network (7) for data transmission between a source station and a number of subscriber stations, using modulation of a carrier frequency. All the subscriber stations coupled to the network (7) use the same transmission carrier frequency, the transmitting stations assigned a credit value which is updated simultaneous with the data transmission. The carrier signals are accurately synchronised, to prevent loss of information upon summation of the transmission signals, via a phase correction circuit (R) for the carrier signal generator (1). ADVANTAGE - Reduced complexity and overall cost.

TL;DR: In this article, a simple yet functional non-intrusive method for electric power measurement that can be applied in energy efficiency programs, in order to provide a better knowledge of the energy consumption of the appliances in a home.
Abstract: Currently a large effort is being done with the intention to educate people about how much energy each electrical appliance uses in their houses, since this knowledge is the fundamental basis of energy efficiency programs that can be managed by the household owners. This paper presents a simple yet functional non-intrusive method for electric power measurement that can be applied in energy efficiency programs, in order to provide a better knowledge of the energy consumption of the appliances in a home.

TL;DR: An architecture of a low-cost ARM-based Smart Metering network designed to be suitable for Smart Grids applications aimed to a more efficient energy use according to the article 13 of Directive 2006/32/EC is presented.
Abstract: In this paper, an architecture of a low-cost ARM-based Smart Metering network is presented. The system is designed to be suitable for Smart Grids applications aimed to a more efficient energy use according to the article 13 of Directive 2006/32/EC. The network is composed by several slave smart meters that continuously monitor loads and energy generator to make available in real-time information such as power and energy consumption/generation and several power quality parameters to a specific master device called data aggregator. This device integrating the information coming from slave smart meters and information regarding co-generator status, the forecast renewable source availability and, through a web service access, current energy prices, can take decisions to apply suitable management strategies aimed at reducing costs.

TL;DR: In this article, an electricity meter which includes a temperature sensing unit for determining a signal representative of the temperature within the meter is described, in which an analog to digital (A/D) converter, a digital signal processor (DSP) and a microcomputer.
Abstract: An electricity meter which, in one embodiment, includes a temperature sensing unit for determining a signal representative of the temperature within the meter is described. In the one embodiment, the meter includes a current sensor, a voltage sensor and a processing unit. The current sensor generates an signal representative of a line current and the voltage sensor generates a signal representative of a line voltage. The current and voltage sensor and temperature sensing unit outputs are coupled to the processing unit. The processing unit includes an analog to digital (A/D) converter, a digital signal processor (DSP) and a microcomputer. The digital outputs of the A/D converter are connected to the DSP. The outputs of the DSP are connected to the microcomputer. Temperature characteristics of the meter are stored within the DSP. In operation, the output signals from the current sensor and the voltage sensor are sampled by the A/D converter to generate digital output signals representative of the line current and the line voltage. The output of the sensing unit is sampled by the A/D converter to generate a digital output signal representative of the temperature within the meter. The A/D converter digital output signals are transmitted to the DSP. The DSP determines if the output signal representative of the temperature within the meter is within a valid range. If the temperature signal is within the valid range, the DSP adjusts the line current and line voltage by the temperature characteristics of the meter based on the temperature representative signal. An adjusted energy consumption value is then determined by the DSP using the adjusted line current and the adjusted line voltage.

TL;DR: In this paper, the characterization of the acquisition channels using measurement data obtained stimulating them with signals generated using a high-accuracy waveform generation module is presented.
Abstract: In this paper, a prototype of an energy monitoring device based on an open source concept is presented. This architecture assures several advantages with respect to traditional energy meters, such as easy development of new applications making cost- and time-effective the migration to future smart grid infrastructures and simple adjustments to change in the relevant standards. The open source philosophy has been adopted designing the software components to make all features easily customizable by the user. In this paper, the characterization of the acquisition channels using measurement data obtained stimulating them with signals generated using a high-accuracy waveform generation module is presented.
