Problems solved by technology

If the shore side power supply is directly used, it is very likely to cause equipment damage or even personal accidents
But there is still no way to effectively ensure the safe connection and power supply between the ship power grid and the shore power supply system.

Embodiment 1

[0061] Embodiment 1 of the present invention provides a shore ship power supply method, such as figure 1 shown, including the following steps:

[0062] 101) At least one auxiliary generator is reserved for ships calling at the port;

[0063] 102) Connect the shore power cable on the ship side with the shore power cable on the shore side;

[0064] 103) Establish a communication connection between the shore power supply system and the ship;

[0065] 104) The shore side power supply system detects the working status of its own shore power equipment, and the ship side detects the working status of its own shore power equipment;

[0066] If both are normal,

[0067] 105) Match the output power system setting on the shore side with the power system on the ship side;

[0068] 106) The ship side leads the power grid to the shore side power supply system;

[0069] 107) Adjust the shore power grid to be consistent with the ship power grid and then connect to the grid;

[0070] 108...

Embodiment 2

[0075] In order to further improve the effect, Embodiment 2 of the present invention improves the shore ship power supply method on the basis of Embodiment 1, such as figure 2 shown, including the following steps:

[0076] 201) At least one auxiliary generator is reserved for ships calling at the port;

[0077] 202) The shore side power supply system detects the working status of its own shore power equipment, and the ship side detects the working status of its own shore power equipment;

[0078] If both are normal,

[0079] 203) Connect the shore power cable on the ship side with the shore power cable on the shore side;

[0080] 204) Establish a communication connection between the shore power supply system and the ship;

[0081] 205) The shore side power supply system detects the working status of its own shore power equipment, and the ship side detects the working status of its own shore power equipment;

[0082] If both are normal,

[0083] 206) The shore side and th...

Embodiment 3

[0103] Before the ship leaves the port, it needs to be disconnected from the shore power supply system, and then powered by its own auxiliary generator. This process is also prone to accidents. In order to reduce the occurrence of accidents, the shore ship power supply method provided by Embodiment 3 of the present invention also includes a separation method, such as Figure 5 As shown, it includes the following steps:

[0104] 301) The ship starts and operates at least one auxiliary generator;

[0105] 302) Connecting the grid of auxiliary generators to the grid of the shore-side power supply system;

[0106] 303) diverting the ship's load to an auxiliary generator;

[0107] 304) Disconnect the shore side power supply system from the ship's power grid;

[0108] 305) Disconnect the ship side communication cable from the shore side communication cable.

Abstract

The invention relates to the field of the guarantee of waterway facilities, in particular to a shore-ship power supply method. An access method comprises the following steps of: remaining at least one of auxiliary generators of an anchored ship to run; connecting a ship-side shore power cable with a shore-side shore power cable; building communication connection between a shore-side power supply system and a ship; detecting the working condition of shore power equipment arranged at a shore side, and detecting the working condition of shore power equipment arranged at a ship side; if the working condition is normal, matching the output rating of the shore side with the rating of the ship side; leading a ship power grid arranged at the ship side to the shore-side power supply system; adjusting a shore-side power grid to be accordant with a ship power grid and connecting the grids; transferring the load of the ship to the shore-side power supply system; and turning off all the auxiliary generators of the ship. Compared with the prior art, the power supply method for the shore ship provided by the invention can realize the automatic grid-connection and the load transfer between the shore side and the ship-side power grid, guarantees the share of the shore-side and ship-side electric information, and is safer to operate, so that the power supply method is more normative, safe and reliable.

Description

technical field [0001] The invention relates to the field of waterway facility guarantee, in particular to a shore ship power supply method. Background technique [0002] The power of the ship during the voyage is generally supplied by the ship's own auxiliary generator, and during the ship's berthing, in order to reduce pollution emissions, the on-board auxiliary generator must be shut down, in order to ensure the operation power requirements of the berthing ship , you need to provide electricity for the ship from the shore. [0003] There are various types of existing ships, and the parameters of the power grid are also different. If the shore side power supply is directly supplied, it is very likely to cause equipment damage or even personal accidents. But there is still no method that can effectively ensure the safe connection and power supply between the ship power grid and the shore power supply system. Contents of the invention [0004] The invention provides a s...
