Abstract
Nowadays, ships with electric propulsion are designed and constructed in Russia. However, the protection of ship frequency converters from short circuits is often not given due attention, making reliability and hardiness of ships with electric propulsion in case of frequency converters accidents an important task. The article considers variants of the construction of ship electric propulsion systems with frequency converters, analyzing factors influencing their reliability and hardiness and describing the frequency converter failure in case of a short circuit and in the event of a power valves accident of an uncontrolled rectifier, as well as giving recommendations on increasing the reliability and survivability of the electric propulsion systems.
Keywords: electric propulsion, ship electrical equipment, frequency converters, main propulsion motor.
