Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
Main promotion diesel engine 3 connects propeller 1 by gear case 2, the rotor that gear case 2 stretches out an axle and magneto-electric machine 4 is simultaneously mechanically connected, the stator winding of magneto-electric machine 4 connects the pusher side output of frequency converter 5, the net side of frequency converter 5 exports by the load 9 of axle belt fuser 6 connected boat, and load 9 peculiar to vessel is also connected with power station diesel powerplant 7 by line circuit breaker 8.
Under traditional mode, line circuit breaker 8 closes, and axle belt fuser 6 disconnects, and frequency converter 5 does not work, and now propeller 1 is driven by main promotion diesel engine 3, and ship service power unit is provided by marine engine group 7, powers to load 9 peculiar to vessel.
Under power generation mode in parallel, line circuit breaker 8 and axle belt fuser 6 all closed, main promotion diesel engine not only drives propelling unit, and unnecessary energy is flowed to magneto-electric machine 4 by gear case 2.When magneto-electric machine 4 rotates, rotor due to magneto-electric machine 4 is permanent magnet and produces rotating field, therefore the stator of magneto-electric machine 4 can produce the voltage that frequency constantly changes along with the rotating speed of propelling unit 1, the voltage progress of disease that frequency and amplitude all change by frequency converter 5 becomes the voltage that frequency and amplitude are all constant, and marine engine group 7 is powered to load 9 peculiar to vessel jointly.
Under independent power generation mode, line circuit breaker 8 can be disconnected, and close marine engine group 7, only closed axle belt fuser 6, is powered to load 9 peculiar to vessel by magneto-electric machine 4 and frequency converter 5.In such a mode, the energy of load 9 peculiar to vessel in fact comes from main promotion diesel engine 3, under such configuration makes main promotion diesel engine 3 be operated in higher POL, namely possesses lower oil consumption.
Under parallel connection propelling pattern, line circuit breaker 8 and axle belt fuser 6 all closed, marine engine group 7 powers not only to load 9 peculiar to vessel, and the net side of energy input converter 5 is exported, the pusher side output driving shaft translator 4 of frequency converter 5, axle translator 4 and main promotion diesel engine 3 are driven by gear case 2 pairs of main thrusters 1 jointly.Can ensure that screw propeller main thruster 1 obtains tractive power extra except main promotion diesel engine 3 like this, promote the propulsion capability of main thruster 1.
Independent propelling pattern is a kind of contingency mode, now main promotion diesel engine 3 damages, advance pattern similar with parallel connection, line circuit breaker 8 and axle belt fuser 6 all closed, marine engine group 7 powers not only to load 9 peculiar to vessel, and the net side of energy input converter 5 is exported, the pusher side output driving shaft translator 4 of frequency converter 5, with parallel connection advance pattern unlike, because main promotion diesel engine 3 damages, all thrust powers of screw propeller main thruster 1 are all come from magneto-electric machine 4, in such a mode, even if main promotion diesel engine 3 damages, screw propeller main thruster 1 still obtains power, therefore the power degree of redundancy of system promotes greatly.
Frequency converter 4 adopts traditional back to back structure, uses the prime power module 10 based on IGBT and diode to form, and pusher side and net side adopt identical full bridge structure, and centre forms DC link by DC capacitor 11.
