A naval electrical engineering and automation strategy is considered that includes improvement of power generation and distribution systems, as well as improvement of electric propulsion systems and propulsion machinery. The effectiveness of the use of valve generator sets and the transition to the distribution of dc electric energy is shown. New-generation static power sources are actively developing in maritime transport. Good adjusting characteristics, an unrestricted number of reverses and minimum speed, high efficiency when working at fractional loads, and high propeller torque capacity significantly expand the applicable scope of modern ac electric propulsion systems. The desire to combine the advantages of different types of propulsion plants facilitated the creation of combined (hybrid) propulsion plants. Combined plants combine a traditional main thermal engine and a propeller motor. A main thermal or propeller electric motor is used depending on the operating mode and the vessel speed. It is concluded that the main tasks in the development of maritime electrical engineering are increasing the energy efficiency of electricity generation by introducing valve generator sets, innovative sources of electricity with high efficiency and environmental friendliness, permanent magnet and inductor-type propeller motors, and combined propulsion machinery with reversible electric propulsion systems.
