Description
Technical field
The present invention relates to a kind of electric propulsion system of all electric propulsion naval vessel.
Background technology
The synthesis electrical method system on conventional all electric propulsion naval vessel comprises one-of-a-kind system and two-generator parallel-running system, and as shown in Figures 1 and 2, Fig. 1 and Fig. 2 does not draw the parts such as cooling system, sensor, battery monitor system to its structure.
Fig. 1 is the conventional synthesis electrical method system architecture schematic diagram of one-of-a-kind system, and diesel powerplant output direct current (DC) carries out energy and confluxes in direct current bus duct, and energy drives propeller system for rear class motor.The program belongs to unit series connection type hybrid power system scheme, and system architecture is simple, but the reliability of system is poor, and when certain link of system breaks down, system is with regard to cisco unity malfunction.
Fig. 2 is the conventional combined power driving system structure schematic diagram of double parallel, and two cover diesel powerplants output direct current (DC) carry out energy and conflux in direct current bus duct, and energy overlaps motor for rear class two and drives propeller system.The program belongs to DC side connect-in strategy, the capacity of electric propulsion system accounts for 90% of ship electric network capacity, the start-up course of propulsion electric machine is along with huge energy requirement, and diesel generation unit or electric propulsion unit is charged is incorporated to or chargedly cuts out DC side and in network process, system topology changes, can system the mode of stable operation to system propose very high requirement, make system control scheme complicated, implement and there is very large difficulty.
Electrical generator and rectifying device are defined as power generation assembly; Inverter and electrical motor are defined as motor driver.The diesel generation cells D G1 that goes out of dotted line collimation mark and DG2 is power generation assembly in figure 3.Middle low power system is not generally controlled by three-phase generator and three-phase or controllable rectifying device is formed, and its structure diagram as shown in Figure 4.Electric propulsion unit P1 and P2 that dotted line collimation mark goes out in figure 3 is motor driver.Middle low power system is generally made up of three-phase inverter and three-phase motor, and its structure diagram as shown in Figure 5.Now the synthesis electrical method system on all electric propulsion naval vessel is made up of jointly central controller, engine controller, driving engine, power generation assembly, motor driver, communication bus, battery, output shaft and cooling system and sensor part.
The conventional combined power driving system structure of one-of-a-kind system, if diesel engine, electrical generator or rectifier any one break down, as generator failure normally winding open circuit, failure in rectifying device normally brachium pontis open circuit, then whole power generation assembly cannot work, and whole system can only rely on energy-storage battery to provide electric energy to carry out low power run.If inverter or motor go wrong, as fault of converter normally brachium pontis open circuit, the normally winding open circuit of drive motor fault, then drive link normally to work, whole system will enter stopped status.From analyzing above, the reliability of the conventional combined power driving system structure of one-of-a-kind system is poor, power generation assembly and any one fault of motor driver, and system will be difficult to run, to systemic breakdown be caused time serious, therefore will improve emphatically the reliability of each link of system.
In the conventional combined power drive system of dual systems, two cover one-of-a-kind systems share a set of direct current bus duct.If when wherein a set of one-of-a-kind system breaks down, failure system can not effectively excise by system, and two cover one-of-a-kind systems can not be operated in separate state.If the direct current bus duct et out of order of system, as line short, system will paralyse.From analyzing above, although the conventional combined power driving system structure of dual systems comparatively one-of-a-kind system reliability increases, but its any one one-of-a-kind system can not work alone, system reliability depends on direct current and to conflux the reliability of busbar, once power generation assembly, motor driver or direct current conflux, busbar breaks down, system can only operate in low power state, will cause systemic breakdown time serious, therefore will improve emphatically the reliability of each link of system.
The naval vessel of relatively high power can adopt polyphase machine technology to improve system reliability usually.When the system failure, multi-phase motor system can use phase shortage control technology to continue to run.But the control relative complex of multi-phase motor system, high and cost is higher to space requirement, be more suitable for the occasion that there is higher-wattage grade, there is larger installing space, be difficult to, that installing space less middle-size and small-size naval vessel field not high at power grade and be applied.
The another kind of method improving the synthesis electrical method system reliability on all electric propulsion naval vessel adopts system backup.Its principle is on naval vessel, adopt k (k>=2) to organize separate synthesis electrical method system, when in certain cover system when rectifier, inverter or motor fault, is switched to other set of system, makes naval vessel continue navigation.This method causes the increase of drive system volume and weight on the one hand, brings the difficulty of a series of installation aspect; On the other hand, owing in most cases only having single cover system work, standby system is in idle state, causes the waste of resource, reduces the economy of whole system.The method improving tandem structure hybrid power electronlmobil reliability as a kind of adopts system backup." the POWER SUPPLY CIRCUIT SYSTEM OF HYBRID ELECTRIC AUTOMOBILE " of Japanese Patent JP2004120906 proposes similar way, its principle is separate inverter and the electrical motor that each axletree adopts k (k>=2), when certain inverter can not work, healthy inverter drives coupled motor, make vehicle operating, thus improve serviceability.This patent adopts the mode of backup to realize redundancy to inverter and drive motor system, does not consider the reliability how improving power generation assembly; And adopt system backup mode easily to cause the increase of volume and weight, install more difficult in vehicle narrow space situation.
Summary of the invention
The object of the invention is to overcome existing all electric propulsion naval vessel Electricity Generation, motor unit is high to space requirement, the shortcoming of the higher and system backup cellular installation difficulty of cost, proposes a kind of naval vessel electric power energy power system.Structure of the present invention is simple, small volume, and control conveniently, there is the high efficiency of good economy and wide region while improving synthesis electrical method system reliability, electric power naval vessel can be met to synthesis electrical method system power demand and reliability requirement.
