Design and Implementation of Self power Wireless Energy Meter for Heat Energy Measurement in Smart Buildings Siamak Jafarpisheh s jafarpisheh@ec iut ac ir January 10 2017 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Dr Ahmadreza Tabesh a tabesh@cc iut ac irAdvisor Dr Mohammad Amin Latify latify@cc iut ac irAdvisor Dr Nasrin Rezaei n Rezaei@ec iut ac irAbstractBuilding management and optimization of energy consumption in residential buildings are among prioritiesfor sustainable energy development in many countries Implementation of energy management systemsrequire online monitoring tools and the building energy related equipment In a residential building especially in large residential complexes heating system consumes the highest amount of energy that is about45 percent of total energy of a building On the other hand in a large building with a shared heating system applying tariff for a fair monthly payment of energy charge has been introduced as an efficient approach toimprove energy management However as calculating the exact share of each apartment unit in energyconsumption cannot be determined despite the superiority of central heating the current trend is towardindependent heating systems One solution is using energy meters which in turn add to the complexity ofinstrumentations in a large building Using wireless communication and replacing batteries with energyharvesters as a permanent power generator are suggested as the two main techniques in the design of easy to install and maintenance free energy meters The subject of this thesis is about developing wireless and self power energy meters based on piezoelectricenergy harvesters and flow meters In this thesis the design analysis and implementation method of apiezoelectric fluid energy harvester using a non contact turbine is proposed that is capable to capture energyof fluid with a wide range of speeds As the generated power by an energy harvester is typically low and inthe range of mW replacing the battery in a wireless energy meter device requires re designing of the devicecircuits with ultra low power sensors and processing circuits A typical Hall effect flow meter due to usingelectronic circuits for signal conditioning has a relatively high power consumption that cannot be supplied bya mW range energy harvester The thesis proposes a piezoelectric passive flow meter device for measuringthe fluid flow rate that aims to reduce power consumption of wireless energy meter In the suggested device energy harvesting from the fluid can also be achieved using the same structure for measuring the flow rate Thus an integrated sensor and energy harvester device is suggested and implemented for reducing the powerconsumption and supplying power to the wireless energy harvester To evaluate the effectiveness of theproposed method an experiment test setup for testing the proposed device is developed The test results showthat the device can measure the flow rate in the range of 95 to 225 lit h and it can capture maximum power of214 micro watts in this range Further it is shown that the average power consumption of the proposedenergy meter is about 113 micro watts which is in the range of supplied power with the energy harvester KeywordsBuilding Energy Management System Self power Wireless Energy Meter PiezoelectricFluid Energy Harvester Piezoelectric Flow Meter Combined Flow Meter and EnergyHarvester
