Problems solved by technology

However, the supercapacitor and battery used as the main power supply of the ship need to be charged and stored on the shore. Once the energy storage of the supercapacitor and battery is used up or fails, the ship will lose power and cause serious damage to the safety of the ship. accidents; secondly, the recoverable braking kinetic energy of the electric propulsion system is generally not generated during the normal navigation of the ship, so the significance of the supercapacitor in the system is not great

Abstract

The invention discloses a ship electric propulsion system with hybrid power supply of a diesel generator set and a power battery. The system comprises a ship control system, a power system, a distribution board and an electric propulsion system, wherein a power management controller and a propulsion manipulation controller are arranged in the ship control system; the power system is connected with the electric propulsion system through the distribution board; the power system and the distribution board are connected with the power management controller respectively; and the electric propulsion system is connected with the propulsion manipulation controller. A shore power distribution box, a diesel generator set and a power battery pack are arranged in the power system; a frequency converter is arranged in the electric propulsion system and connected with a propulsion motor; the propulsion motor is connected with a propeller; a busbar is arranged in the distribution board and provided with a main switch and a load switch; the main switch is connected with the generator set; and the load switch is connected with the frequency converter. By adopting the hybrid power supply mode of diesel generator set and power battery, the safe sailing of the ship is ensured, and the continuation performance of the ship is improved.

Description

technical field [0001] The invention relates to a marine electric propulsion system powered by a hybrid power supply of a diesel generator set and a power battery. Background technique [0002] The electric propulsion mode of the ship has the obvious advantages of good maneuverability, energy saving and environmental protection, which can reduce the exhaust gas emission of the ship, reduce the fuel energy consumption of the ship, and obtain better power characteristics at the same time. Chinese patent 201010300192.X discloses an electric propulsion system including a diesel engine-generator set, a power distribution system, a propulsion motor and a propeller; Chinese patent 200810034693.0 discloses a control device and a control method for an electric propulsion ship. In the above-mentioned patents, the main power sources of the electric propulsion ships are conventional diesel engine-generator sets (diesel generator sets for short). Such an electric propulsion system power...
