Abstract
With the development of power electronic systems, the use of a shaft generator in ship power plant systems is becoming more widespread. The use of the Permanent Magnet Synchronous Generator (PMSG) in these systems instead of the commonly used Electrically Excited Synchronous Generator (EESG) results in increased propulsion efficiency and reliability of the ship’s power plant. The lack of a voltage regulator in PMSG requires the use of an electronic power converter to maintain constant voltage parameters in the ship’s network, consisting of an active rectifier (AR) and an active network inverter (AI). The article presents AR tests in the PMAG-AR system, whose task is to maintain a constant voltage of the DC circuit when the shaft speed and load changes, as a result of which the selection of AI remains a simple choice. Energy optimization of the shaft generator system was also carried out, which allows reducing losses in AR and PMSG by limiting reactive power in the PMSG-AR system, which is particularly important in high power plants.
