Embodiment 1

[0033] This embodiment provides a power supply system for an electric push rescue ship, figure 2 It shows a structural block diagram of the power supply system of the electric propelled rescue ship provided by the embodiment of the present invention. like figure 2 As shown, the power supply system of the electric propulsion rescue ship includes at least two sets of generator sets, a high-voltage switchboard, a low-voltage switchboard and a power propulsion device. The high-voltage switchboard is provided with a high-voltage busbar, and the low-voltage switchboard Equipped with low voltage busbar. The first generator set includes a high-power generator 1G and a low-power generator 3G, and the second generator set includes a high-power generator 2G and a low-power generator 4G. The generator set is connected to the power propulsion device through the high-voltage busbar, and the power propulsion device includes a first power propulsion device and a second power propulsion de...

Embodiment 2

[0040] On the basis of the first embodiment above, this embodiment provides a specific electric power supply system for a rescue ship, such as image 3 As shown, the power supply system of the electrically propelled rescue ship includes at least two sets of generator sets, a high-voltage switchboard, a low-voltage switchboard and a power propulsion device. Each set of generators includes a high-power generator of 2600kW and a small-power generator of 450kW. The power propulsion device includes the main thruster and the bow side thruster. The main thruster is used to propel the forward direction of the ship, and the bow thruster is used as the auxiliary control device of the ship, which is widely used in the manipulation of ships in the port. The lateral movement of the ship in the dock and the adjustment of the course when sailing at low speed in the channel are bow-side propulsion. The specific application of the device in ship maneuvering. In the dynamic positioning condit...

Embodiment 3

[0049] On the basis of the above embodiments, this embodiment provides an electric rescue ship, including: lighting equipment connected to the power supply system of the electric rescue ship in any of the above embodiments; the power supply system of the electric rescue ship The power supply system of the above-mentioned electrically propelled rescue ship is adopted.

[0050] Specifically, the lighting equipment includes cabin main lighting, outdoor channel lighting, deck lighting, searchlights and floodlights, and navigation signal lights. The lighting equipment is connected to the electric rescue ship through the 230V busbar on the low-voltage switchboard. A lighting transformer is arranged between the low-voltage busbars on the low-voltage distribution board. When the main power supply fails, the lighting equipment is supplied with power by the emergency generator on the emergency switchboard.

[0051] The power supply system of the electric propulsion rescue ship adopted ...

Abstract

The invention provides a power supply system of an electric propulsion rescue ship, and the electric propulsion rescue ship. The power supply system and the electric propulsion rescue ship relate to the technical field of ships. The power supply system includes at least two sets of generator sets, a high voltage switchboard, a low voltage switchboard, and a power propulsion device. The high voltage switchboard is provided with a high voltage busbar, and the low voltage switchboard is provided with a low voltage busbar; each set of the generator sets includes a high power generator and a low power generator, and the high power generator is connected to the power propulsion device through the high voltage busbar; the low power generator is connected to the low voltage busbar through the highvoltage busbar; and a switch assembly is disposed between a connection point of the high power generator and the high voltage busbar and the connection point between the low power generator and the high voltage busbar. The power supply system solves the technical problem of reverse power and trip of the low power generator caused by a high-power load under the working condition of parallel operation, and achieves the technical effects that the low-power generator does not have the problem of the reverse power and the trip when the high-power load occurs under the working condition of paralleloperation.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a power supply system for an electric-push rescue ship and the electric-push rescue ship. Background technique [0002] The electric propulsion rescue ship is characterized by a long standby period, high speed requirements in emergency situations, and high power output in rescue conditions. The standby period accounts for more than 80% of the entire mission period of the rescue ship, but the execution of the mission must ensure the high speed to rush to the rescue site and the use of high-power electrical equipment during rescue. Under the premise of ensuring the successful completion of the rescue mission, and taking into account the economy during the standby period, the power station is equipped with a high-power generator set of 2600kW×2 and a low-power generator set of 450kW×2, and the power ratio of the large and small power generator sets reaches 5.78:1. [0003] Under dyna...
