Control Strategy of Multi-Voltage Output Emergency Power Supply System Based on Dual-Stator Winding Induction Generator

Emergency power supplies, such as diesel generator vehicles, are a core component of modern power security systems, playing an irreplaceable role in maintaining the operation of critical infrastructure and reducing losses from unexpected power outages. However, conventional mobile diesel generator vehicles are limited by their single voltage output, which does not support multi-voltage operational scenarios, and they suffer from low efficiency and high costs when operating at low power levels. In response to these challenges, this paper proposes a novel dieselstorage hybrid power supply architecture based on dual-stator winding induction generator (DWIG). By leveraging the multiwinding characteristics of DWIG to achieve multi-voltage outputs and efficiently integrating them with energy storage, and by developing multi-mode control strategies, the proposed system ensures high efficiency and reliability across all scenarios. Simulation results validate the feasibility of the proposed architecture and its control strategies.
