By using the electric power system for the platform supply ship with dynamic positioning, when the electric power system breaks down, influence to safe operation of a ship is small, and reliability of the product is high.
Description
Technical field
The present invention relates to Ship Electrical Power System field, is the electric power system of the platform supply vessel of a kind of drive location specifically.
Background technology
In the electric power system of prior art Conventional Ship, main distribution board generally comprises the parts such as bus-bar, generator, generator main switch, load, load switch.Because the bus-bar of main distribution board is divided into two sections of A, B, visual plant is generally powered by two sections of bus-bars, and one primary, and one standby, and be provided with interconnection switch between two bus-bars.Although this distribution panelboard is simple in structure, but reliability is not high, reason is, when a certain generator or one section of bus-bar break down, need to isolate it, the interconnection switch in the middle of being about to disconnects, thereby out of order part isolation, therefore have at least the equipment of half to lose power supply, fault incidence is large, thereby affects the safe operation of boats and ships.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide the electric power system of the platform supply vessel of a kind of drive location, the technical problem that fault incidence is large, reliability is low existing for solving above-mentioned prior art.
Technical solution of the present invention is, a kind of electric power system of platform supply vessel of drive location of following structure is provided, comprise a plurality of fuel electric generators and at least two pairs of bus-bars, described fuel electric generator is with single bus-bar by the corresponding connection of generator main switch, and described bus-bar connects load by load switch; Two bus-bars in every pair of bus-bar connect by interconnection switch, between two pairs of bus-bars, also by interconnection switch, connect one to one.
Adopt above structure, the present invention compared with prior art has the following advantages: because the present invention adopts multipair bus-bar, two bus-bars in every pair of bus-bar connect by interconnection switch, between two pairs of bus-bars, also by interconnection switch, connect one to one, when a fuel electric generator breaks down therein, the generator main switch being connected with generator disconnects, and fault generator is isolated; During certain load equipment fault, the load switch being connected with equipment disconnects, and avoids having influence on bus-bar; If single bus-bar breaks down, disconnect the interconnection switch of the bus-bar being attached thereto, thereby fault is limited in to a smaller scope, because the equipment that single bus-bar connects is fewer with respect to whole system, safe operation impact on boats and ships is less, has also improved the reliability of product.
As improvement, described electric power system also comprises the fire pump as load, and described fire pump is connected with bus-bar by load switch; Concerning single power consumption equipment, electric energy is from fuel electric generator → bus-bar → certain load, form a current supply circuit, the form that can form current supply circuit is more, and the reliability of power supply is higher, here for fire pump, can realize a plurality of current supply circuits, even if there is wherein one or two loop bus-bar fault, fire pump can also normal power supply work, has further improved reliability and the security performance of product.
As improvement, electric power system also comprises controller, and described controller is and is electrically connected to load switch, generator main switch, interconnection switch; When corresponding component breaks down, fault-signal enters controller, is made the instruction that disconnects some switch, thereby dependent failure parts are isolated by controller.
As improvement, wherein have at least a bus-bar only to connect a fuel electric generator, also exist a bus-bar to connect many fuel electric generators; For important equipment, need to be connected on the bus-bar with many fuel electric generators, in order to avoid the generator on a certain bus-bar damages and cause this bus-bar nearby to visual plant power supply, to affect safe handling.

Embodiment
Below will with regard to specific embodiment, the invention will be further described, clear in order to illustrate, accompanying drawing do not illustrate controller with and annexation, but those of ordinary skills can know from the description of specification.
As shown in Figure 1, the electric power system of the platform supply vessel of drive of the present invention location, comprise a plurality of fuel electric generators 1 and at least two pairs of bus-bars 2, described fuel electric generator 1 is with single bus-bar 2 by the corresponding connection of generator main switch 3, and described bus-bar 2 connects load by load switch 4; Two bus-bars in every pair of bus-bar 2 connect by interconnection switch 5, between two pairs of bus-bars 2, also by interconnection switch 5, connect one to one.In the present embodiment, electric power system is arranged on distribution panelboard 6, two pairs of bus-bars of actual employing, and what shown in figure, be arranged in parallel is a pair of bus-bar, between upper and lower two pairs of bus-bars, by interconnection switch, connects.Part bus-bar only connects a fuel electric generator, and another part is connected with a plurality of fuel electric generators.
Described electric power system also comprises the fire pump 7 as load, and described fire pump 7 is connected with bus-bar 2 by load switch 4.For fire pump, can realize a plurality of current supply circuits, even if there is wherein one or two loop bus-bar fault, fire pump can also normal power supply work.
Electric power system also comprises controller, and described controller is and is electrically connected to load switch 4, generator main switch 3, interconnection switch 5.Adopt controller to control each switch, the isolation while realizing fault, and can discharge rapidly fault.
Wherein have at least a bus-bar only to connect a fuel electric generator, also exist a bus-bar to connect many fuel electric generators.
Operation principle of the present invention is as follows: two bus-bars in every pair of bus-bar connect by interconnection switch, between two pairs of bus-bars, also by interconnection switch, connect one to one, when a fuel electric generator breaks down therein, the generator main switch being connected with generator disconnects, and fault generator is isolated; During certain load equipment fault, the load switch being connected with equipment disconnects, and avoids having influence on bus-bar; If single bus-bar breaks down, disconnect the interconnection switch of the bus-bar being attached thereto, thereby fault is limited in to a smaller scope.
