Energy Consumption Forecasting for Smart Meters

Earth, water, air, food, shelter and energy are essential factors required for human being to survive on the planet. Among this energy plays a key role in our day to day living including giving lighting, cooling and heating of shelter, preparation of food. Due to this interdependency, energy, specifically electricity, production and distribution became a high tech industry. Unlike other industr...

Error Modeling of Static Energy Meters

− The scope here is to derive a model of the measurement error of static energy meters. The model proposed is based on three error parameters: gain, phase and bias error. The validity of the model is confirmed through the statistical analysis of the measurement results obtained during the calibration of a commercial energy meter, compliant with the Measuring Instruments Directive 2004/22/EC. Th...

Transient detection and classification in energy meters

M. Nagaraju, M. Naresh and S. Jayasimha Signion Systems Ltd., Hyderabad Abstract Power quality tariffs/ incentives provide an impetus to increased discipline in the emerging deregulated power network scenario. Periodic deviations from desired voltage and currents are measured by line frequency deviation, power factor and harmonics (magnitude and phases) while non-periodic deviations are measure...

AN939, Designing Energy Meters with the PIC16F873A

The deployment of electronic energy meters has gained a great deal of momentum over the past several years. This is due to their two main advantages over the traditional electromechanical designs: improved accuracy and an expanded set of features. Current microcontroller technology allows designers to build meters that are competitive in price with traditional devices, while maintaining the req...
