Technical field
The invention belongs to ship power systems technology field, be specifically related to pleasure-boat electric propulsion powersupply system.
Background technology
Because the overall vibration noise level of watercraft electric propulsion system is lower than the direct propulsion system of conventional diesel engine, so the application of electric propulsion system on pleasure-boat more and more widely.
Conventional pleasure-boat electric propulsion system adopts diesel generating set as power supply or adopts battery pack as power supply, and the two does not coexist usually.Adopt diesel generating set can provide bigger propeller power as the pleasure-boat of power supply, cruising time is long, but oil consumption and vibration noise level adopt battery pack as the power supply height; Adopt battery pack as the pleasure-boat of power supply owing to be subjected to the restriction of battery pack dimensional weight, propeller power is little, generally is no more than 1/3 of diesel generating set propeller power, cruising time is short, be generally 2-4 hours, but oil consumption is low, quietness is good.
When pleasure-boat drives towards the on-board and off-board of target harbour or visit zone, wish speed of a ship or plane height, propeller power is big, adopt diesel-electric set electric supply to meet the demands, when pleasure-boat arrives the visit zone, wish low speed, quiet, adopt battery-powered meeting the demands, if two kinds of power supplys can be combined, and realize the automatic conversion of two kinds of power supplys, a kind of brand-new pleasure-boat electric propulsion power-supply system can be provided.
Summary of the invention
The object of the present invention is to provide a kind of pleasure-boat electric propulsion powersupply system that can bring into play diesel generating set and battery pack advantage simultaneously.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Referring to figs. 1 through shown in Figure 5, the invention discloses a kind of pleasure-boat electric propulsion powersupply system, comprise diesel generating set 1, battery pack 3 and dc bus 7, described diesel generating set 1 is common low pressure three-phase marine diesel oil generating set, battery pack 3 is common plumbic acid battery pack, dc bus 7 is common copper bar, described diesel generating set 1 is by being that galvanic rectifier 2 is connected with dc bus 7 with the three-phase alternating current electric rectification, rectifier 2 is common three-phase six pulse diode rectifier, described battery pack 3 is connected with dc bus 7 after boosting by battery pack stepup transformer 5, battery pack stepup transformer 5 has battery voltage is risen to the BOOST booster circuit that is higher than diesel generating set 1, be parallel with the group charger 4 that is electrically connected with bank on the battery pack 3, group charger 4 is the phase control rectifier charger, on the dc bus 7 respectively the daily load of promising pleasure-boat in parallel provide three-phase alternating current inverter 6 and with the propulsion electric machine M that advances frequency converter 8 to be connected, propulsion electric machine M connects screw 9, when pleasure-boat navigates by water at a high speed, automatically adopt diesel generating set 1 to be the electric propulsion system power supply, during the pleasure-boat lowsteaming, automatically adopt battery pack 3 to be the electric propulsion system power supply, and full ship can not have a power failure when changing automatically by diesel generating set 1 power supply with between by battery pack 3, and power consumption equipment is also unaffected.
When marine low speed is navigated by water, diesel generating set 1 is in closed condition, battery pack 3 gives dc bus 7 power supplies by battery pack stepup transformer 5, voltage after battery pack stepup transformer 5 boosts is V1, be the current voltage of dc bus 7, supply capability propulsion system of the direct current on the dc bus 7 is namely by advancing frequency converter 8 to drive propulsion electric machine M, another part is supplied with inverter 6, gives pleasure-boat daily load power supply after being reverse into three-phase alternating current by inverter 6.
When boats and ships are transformed into when navigating by water at a high speed by lowsteaming, start diesel generating set 1, if the voltage after 2 rectifications of diesel generating set 1 process rectifier is V2, during design, make V2 be lower than V1 after battery pack 3 is boosted through battery pack stepup transformers 5, therefore dc bus 7 voltages still are V1, diesel generating set 1 zero load, stop battery pack stepup transformer 5 this moment, dc bus 7 voltages are reduced to V2, be transformed into by diesel generating set 1 power supply, guarantee during design that the power consumption equipment that voltage is lower than on the V2 dc bus 7 also can operate as normal just can realize the conversion that do not have a power failure.
When boats and ships are transformed into lowsteaming by the high speed navigation, start battery pack stepup transformer 5, because battery pack 3 process battery pack stepup transformers 5 back voltage V1 are higher than the voltage V2 after diesel generating set 1 rectification, then the rectifier bridge behind the diesel generating set 1 is blocked, dc bus 7 voltages rise to V1 by V2, diesel generating set 1 zero load is fully by battery pack 3 power supplies.At this moment, do not have a power failure and switch to battery pack 3 power supply.
Above-described embodiment is illustrative principle of the present invention and effect thereof only; and the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
