Description

Technical Field

[0001] The invention belongs to the technical field of ship power system architecture, and in particular relates to a main network of a double-jump-wire ship power system with a load panel and a control panel spaced apart, and a configuration method thereof. Background Art

[0002] Based on the vitality requirements in ship design, generally larger ships are equipped with two power stations, each with two (or more) generator sets, and each with a main switchboard, which monitors and controls the generator sets and the main network of the power station, and distributes power to the primary network distribution equipment. The main switchboards of different power stations are connected by jumper cables (single jumper cables).

[0003] The main switchboard consists of a control panel and a load panel. The control panel includes a generator control panel, a busbar panel, and a jumper panel. The generator control panel completes the monitoring and control function of the generator set. The busbar switch in the busbar panel is used to connect the busbars of different generator sets. The jumper switch in the jumper panel is used to connect the jumper cables between different power stations. The load panel completes the function of distributing electricity and is generally set on both sides of the control panel, such as Figure 1 shown. The above network is very suitable for power station configurations with no more than two units in a single power station. However, due to the development of equipment and ship technology, the capacity requirements for ship power systems are getting higher and higher, and there will inevitably be power station configurations with more than two units in a single power station. At this time, if the above traditional network structure is adopted, according to the specification requirements, the main switchboard bus should be "greater than the rated current of a generator set with the largest capacity plus 80% of the total rated current of the remaining generators in this power station." At this time, the working current requirements for the bus and protection devices in the main switchboard are greatly increased, which greatly increases the difficulty and production costs of the main switchboard, and may even exceed the processing technology capabilities of the bus. At the same time, due to the high working current of the bus and protection devices, the size and weight of the main switchboard will increase proportionally, which will inevitably increase the overall resource consumption of the ship. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a main network of a double-jump-wired ship power system with a load panel and a control panel separated and a configuration method for adapting to the configuration of multiple units in a single power station of a ship power system.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a main network of a double-jump-wire ship power system with a load panel and a control panel separated, including a main distribution board corresponding to the number of power stations, and a bus on the main distribution board corresponding to the number of generator sets configured in a single power station; it also includes a bus tie switch arranged between the bus bars in the main distribution board; assuming that a single power station is configured with n units; it also includes double jumper wires, and the lead-out points of the two jumper wires are respectively located between the bus tie switches of the (n / 2-1)th to n / 2th buses from the two ends of the main distribution board to the middle.

[0006] According to the above scheme, it also includes a generator set switch connecting the busbar and the generator.

[0007] Furthermore, each section of the bus is provided with a generator set switch.

[0008] According to the above scheme, a load switch connecting the bus bar and the load is also included.

[0009] According to the above scheme, a jumper switch connecting the busbar and the jumper wire is also included.

[0010] Furthermore, the generator set switch and the bus tie switch are arranged on both sides of the jumper switch.

[0011] Furthermore, a load switch is provided between each generator set switch, the jumper switch and the bus tie switch.

[0012] A configuration method comprises the following steps: A main switchboard corresponding to the number of power stations is set up, and buses corresponding to the number of generator sets in a single power station are arranged on the main switchboard; A bus tie switch is provided between the busbars in the main switchboard; Assume that a single power station is equipped with n units; set up double jumper wires so that the lead-out points of the two jumper wires are located between the bus tie switches from the (n / 2-1)th to the n / 2th buses in the middle from both ends of the main distribution board.

[0013] Furthermore, the method further comprises the following steps: Set up the generator set switch connecting the busbar and the generator; Set up a load switch connecting the bus and the load; Each bus section is equipped with a generator set switch.

[0014] Furthermore, the method further comprises the following steps: A jumper switch is provided to connect the busbar and the jumper wire; the generator set switch and the bus tie switch are provided on both sides of the jumper switch; and a load switch is provided between each generator set switch, the jumper switch and the bus tie switch.

The present invention discloses a main network and configuration method of a ship power system with double jumper wires separated by a load panel and a control panel. The main network and configuration method adopt a main distribution board corresponding to the number of power stations, and a busbar on the main distribution board corresponding to the number of generator sets configured in a single power station; a busbar is arranged along the length direction of the busbar, and a busbar tie switch is arranged on the busbar; a single power station is configured with n units; jumper wires are arranged so that the lead-out point of the jumper wires is located between the busbar tie switches of the (n / 2-1)th to n / 2th buses from both ends of the main distribution board to the middle, thereby realizing the function of adapting to the configuration of multiple units in a single power station of the ship power system.

[0016] 2. The present invention solves the problem that when a single power station of a ship power system is equipped with 3 or more generator sets, the requirements for the busbars and protection devices in the main switchboard are greatly increased, which makes the development of the main switchboard difficult and consumes too much overall resources of the ship.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Example 1 See also Figure 2 A main network of a ship power system with double jumper wires separated by a load panel and a control panel, comprising a main switchboard corresponding to the number of power stations, and buses on the main switchboard corresponding to the number of generator sets configured in a single power station; also comprising bus-tie switches arranged between the buses in the main switchboard; assuming that a single power station is configured with n generator sets; also comprising double jumper wires, the lead-out points of the two jumper wires are respectively located between the bus-tie switches of the (n / 2-1)th to the n / 2th buses from both ends of the main switchboard to the middle.

[0025] Furthermore, it also includes a generator set switch connecting the busbar and the generator.

[0026] Furthermore, each section of the bus is provided with a generator set switch.

[0027] Also included is a load switch for connecting the busbar and the load.

[0028] Also included is a jumper switch for connecting the busbar and the jumper wire.

[0029] Furthermore, the generator set switch and the bus tie switch are arranged on both sides of the jumper switch.

[0030] Furthermore, a load switch is provided between each generator set switch, the jumper switch and the bus tie switch.

[0031] This embodiment realizes the function of adapting to the configuration of multiple units in a single power station of a ship power system by adopting a main distribution board corresponding to the number of power stations and a busbar on the main distribution board corresponding to the number of generator sets configured in a single power station; arranging a busbar along the length direction of the busbar, and providing a bus tie switch on the busbar; assuming that a single power station is configured with n units; arranging jumper wires so that the lead-out points of the jumper wires are located between the bus tie switches of the (n / 2-1)th to the n / 2th buses from both ends of the main distribution board to the middle, thereby realizing the function of adapting to the configuration of multiple units in a single power station of a ship power system.

[0032] Example 2 The structure and principle of this embodiment are the same as those of Embodiment 1, except that the above structure is applied to a specific example.

[0034] The power station composition and connection method of the prior art are as follows Figure 1 As shown in the figure, the load panels (1) are set on both sides of the control panel and a single jumper is set. According to the specification, the busbar of the main switchboard should be "greater than the rated current of the largest generator set plus 80% of the total rated current of the remaining generators in the power station." At this time, the operating current requirement for the busbar and protection devices in the main switchboard is not less than I e +2I e *80%, which is 2.6I e .

[0035] The power station composition and connection method of the optimized power network structure proposed by the present invention are as follows: Figure 2 As shown. Since each generator set bus is equipped with a load panel, the power is distributed to the primary power grid, effectively decomposing the working current pressure of the main distribution board bus; at the same time, the double jumper configuration and the optimized setting of the access point not only relieve the current pressure on the jumper line, but also provide more combinations for the reconstruction of the entire system, thus improving the vitality of the system. After simulation analysis and calculation, the working current requirement for the bus and protection devices in the main distribution board is not less than 1.8I e .

[0036] From the above scheme, it can be seen that for large ships with large generator capacity (i.e. I e It can effectively alleviate the development pressure and overall resource consumption of the main switchboard when the number of configurations is large.
