Electrical energy meter design and realization guy rostand kougang

University of Yaoundé I National Advanced School Of Engineering Department of electrical Engineering ELECTRICAL ENERGY METER DESIGN AND REALIZATION By Guy Rostand KOUGANG June C ABSTRACT Most energy consumers complain about their monthly energy bill delivered by the energy provider after the reading the actual meter index and subtracting the previous month index This work presents the root of designing and realization of a digital energy meter of electrical characteristics A V Hz single phase As the results are interesting it can be used as palliative to the actual complaint of electric energy consumers provided energy tari ? is reprogrammed to meet their local ones Then they can in life follow their energy consumptions tari ? and bill without necessary waiting the local operator agents Key words digital meter electrical energy design realization energy bill RESUME La plupart des consommateurs d ? énergie se plaignent des factures énergétiques mensuelles délivrées par leurs approvisionneurs après le relevé du nouvel index et la soustraction de l ? ancien index Ce travail présente les bases de la conception et la réalisation d ? un compteur digital d ? énergie électrique aux caractéristiques A V Hz monophasé Les résultats étant intéressant il peut être utilisé comme palliatif aux plaintes actuelles à condition que les tarifs soient reprogrammés selon les tarifs de la zone de son utilisation Ainsi les consommateurs pourront en permanence suivre leur consommation et tarif sans nécessairement attendre la venue de l ? opérateur Mots clés Compteur numérique énergie électrique conception réalisation facture énergétique C Contents ABSTRACT RESUME List of abbreviations List of variables List of tables List of ?gures CHAPTER GENERAL INTRODUCTION -Background and context of the study -Problem statement -Research question -Research hypothesis -Scope and objectives of the study - Achievements -Overview of Dissertation -De ?nition of terms Chapter Literature review on energy meters Introduction I- De ?nition of an energy meter -Direct current DC - Alternating current AC -Unit of measurement II-Types of meters -Electromechanical meters - Electronic meters -Solid-state design III-Applications - Multiple tari ? variable rate meters -Domestic usage -Commercial usage -Appliance energy meters C -In-home energy use displays -Smart meters -Prepayment meters - Time of day metering -Power export metering - Location IV-Customer drop and metering equation V- Tampering and security Conclusion Chapter Material and methods Introduction I-Block diagram -Blocks description a- Electrical installation b- Transducing c- DC supply d- Conditioning e- Processing f- Displaying - Block calculation a- Sensing and conditioning a Current transducer Microcontroller protection -DC supply - General layout of the circuit -List of materials II- Data processing ow chart Conclusion CHAPTER REALIZATION AND RESULTS ANALYSIS Introduction I-Realized device II-Measurements done with the meter III-Comment of the results IV- Possible sources of errors in measuring the energy CDigitally signed by Guy Rostand KOUGANG DN cn Guy Rostand KOUGANG c CM ou GEDH email g rostandkouga ng gmail com Reason J'ai revu ce document Location gauche Date ' ' V-Advantages and drawbacks of the meter - Meter Characteristics - Meter advantages - Meter limitations
