The unreliability of the energy system to provide a proper account of energy utilized by consumers has been a huge burden on the distribution system network. Different metering methods and designs to detect and prevent fraud, employed in the past have proven fruitless, thus signalling the need for a much smarter energy metering system. The most frequent problem is electricity larceny, this has incurred a major economic loss in the energy distribution system. To this end, this paper presents the distinctive design and hybrid simulation of a larceny deterrent energy evaluation system, capable of detecting different methods of energy theft within power consumer premises. The method employed comprises of deep understudy of previous work in this field, a model is proposed and is simulated under good working conditions and several theft situations using MATLAB while the hardware is simulated using Proteus 8.1 and Arduino software. In conclusion, the efficiency of the proposed system is evaluated by employing different electric theft algorithms, with the results indicating significant energy cost savings in the distribution network.
To meet the ever rising demand for power, innovative measures has to been put into place as convention power sources are fast depreciating. In light of the above, this study opines the distinctive design and fabrication of a small scale model speed breaker electric power generator by harnessing the kinetic energy from vehicles with goal of generating electric power. The model was developed utilizing available electrical and mechanical components such as flywheel (FW), battery, inverter, spring, rack and pinion, and DC motor. To this end, the aim of this paper is accomplished by demonstrating the process of conversion of kinetic energy to electrical energy using a movable speed breaker mechanism and show that it can produce adequate amount of power for streets lights and traffic lights. In light of the above, methodology employed to achieve the above includes the construction of a small scale model of the speed breaker generator; using adequate power calculations, design specification with proper review of related works. In conclusion, the proposed model was developed and constructed in such a way that little applied pressure manually (by hand) on the speed breaker caused generation of electrical power. The technical feasibility of this model is illustrated in real case scenario at Ikpoba hill in upper mission extension in Uteh community employed as a case study.
The variability of critical load demands has led to an increasing push for a clean, sufficient and reliable power supply. Employing innovative techniques to address this need, is a feat yet to be met by several developing nations. Inverter systems based on battery storage provide the extra energy supply to these loads, due to the unavailability of the general power supply. Nevertheless, discharging/charging values of energy demands at peak levels notably affect the performance of batteries. Interestingly, an integrated energy system incorporating power and energy densities of high value can be supplied by combining batteries and other storage devices, in this context super-capacitors (SC). In light of the above, this paper presents the hybrid combination of battery cells and a super-capacitor bank storage system, highlighting its design as well as performance assessment aimed at improving the battery’s life span and its performance while on-load. A novel automatic switching system (ASS) is incorporated to establish a parallel connection between the battery and SC. The ASS detects energy signals from either source of power considered and engages the battery/super-capacitor hybrid system, either to charge or serve as a source of energy to the load. The results show that a significant initial value of transient current is supplied by the super-capacitor. The current draw at peak level is drastically reduced on the battery. This also results in economical savings in cost and increased reliability, which has been necessitated in the backup energy market.
