Voltage Stabilization in Shipboard Diesel-PMSG Autonomous Set Using a Parallel-Connected Converter

The paper presents an innovative method of voltage stabilization in a ship’s power supply system, which involves controlling a converter connected in parallel with a permanent magnet synchronous generator (PMSG) as the main part of an autonomous power generation unit. The proposed solution addresses the critical challenges of maintaining a stable voltage level under varying load conditions typical of marine power plants, which often face unpredictable operational demands. The novel system topology and the proposed converter control strategy enable precise regulation of the output voltage supplied to the ship’s loads, ensuring high power quality, enhanced system reliability, and improved operational efficiency. The results of simulations and experiments presented in the article, which are confirmed by analytical studies, demonstrate the effectiveness and reliability of the developed voltage stabilization method. This concept holds significant potential for application in modern maritime power systems, contributing to the advancement of autonomous, energy-efficient, and environmentally friendly shipboard electrical technologies.
