Hardware-In-Loop Approach of ELC with Battery Storage as Dump Load in Off-Grid SEIG

The Self-excited Induction Generator (SEIG) is widely employed as a significant power generation source in geographically isolated rural areas inside the nation. Nevertheless, the functionality of the machine is limited by the fluctuating loading circumstances at its output. The uninterrupted provision of power supply is crucial for the efficient functioning of the system, as it ensures the continuous delivery of electricity to meet the demands of the consumer load. The utilization of an Electronic Load Controller (ELC) is employed within a self-excited induction generator system with the objective of sustaining a consistent voltage and frequency at the bus bar. One of the benefits of this technology is its ability to store and utilize excess kinetic energy at the receiving end for various purposes in rural regions. The study utilized induction machines with a power rating of 2.2 kW and a current rating of 4.8A. These machines were designed to operate at a voltage of 415 V and a frequency of 50 Hz. The excitation capacitor of the machines was employed to supply power to a three-phase load. Excess power generated is stored in a dump load battery. The suggested system underwent testing in the MATLAB/SIMULINK environment and was afterwards verified using the OP4510 RCP/HIL FPGA-based real-time simulator.
