  • Design and Analysis of an Electromechanical Battery for Rural Electrification in Sub-Saharan Africa
    IEEE Transactions on Energy Conversion, 2011
    Co-Authors: Richard Okou, Mohamed Azeem Khan, Paul Barendse, Adoniya Ben Sebitosi, Pragasen Pillay
    Abstract:

    This paper presents the design and analysis of an electromechanical flywheel energy storage system to enhance rural electrification in sub-Saharan Africa. The system consists of a flywheel rotor, an electrical machine, control system, bearings, and a Containment Structure. With the exception of the power electronics and magnets, local materials were used for the manufacture of the flywheel system. The flywheel rotor is made from glass fiber-epoxy composite, designed using novel shape profiles and utilizes a stress based solution by introducing a central hole for shaft inclusion. The system was accelerated to 6000 r/min storing up to 227 kJ. Numerical stress analyses were performed during the design stage to ensure that the maximum tensile strength is not exceeded. A lumped parameter thermal model is used to estimate the temperature distribution to ensure safe operating conditions of the flywheel system and environment. A life cycle cost analysis performed found that by integrating a flywheel system into a Solar Home System implies a cost savings of 35% per kilowatthour when compared with lead-acid batteries.

  • Analysis of an electromechanical battery for rural electrification in sub-Saharan Africa

    Abstract:

    This paper presents the thermal and structural analysis of an electromechanical battery energy storage system designed to enhance rural electrification in sub-Saharan Africa. The system consists of a flywheel rotor, an electrical machine, bearings and a Containment Structure. The flywheel rotor was constructed from E-glass fiber, the machine from imported NdFeB magnets and commercial energy efficient bearings. With the exception of the power electronics and magnets, local materials were used for the manufacture of the flywheel system. The system was designed to operate between 8,000 rpm to 25,000 rpm with a rated storage capacity of 300Wh. Numerical stress analysis was performed during the design stage to ensure that the maximum tensile strength is not exceeded. A lumped parameter thermal model was used to estimate the temperature distribution to ensure safe operating conditions of the flywheel system and environment. The results of both analyses are presented.
