Description of the drawings
Fig. 1 is the block diagram of the present invention.
Specific implementation mode
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of pure electric vehicle AC power output system device peculiar to vessel, as shown in Figure 1, including
Digitial controller, DC power-supply system busbar, precharge device system and device and inverter, the digitial controller respectively with directly
Stream power supply system busbar, precharge device system and device are connected with inverter, and the precharge device system and device is for completing
Start the ramp input of the soft start and voltage of moment.The digitial controller also respectively with input terminal insulation monitoring device, just
String wave processing unit is connected with break-make protection switching device.
Digitial controller is made of DSP+FPGA devices, and the core important document of this system device, this core component are constituted with this
It completes embedded internal network and couples with data/address bus, there are many modes that this unit couples with subordinate's each unit,
Wherein there is the interface network of communication data, or directly contact the designated lane of logic controller, or couples number for storage unit
Ju Zhan transmission etc..
This control device uses the framework of internal network, to all devices electrical system of subordinate implement control and
Management.
There is this controller the core of core to control ability, complete to exercise supervision control pipe to all devices administered
Reason, so that all periods are all in stable output operating mode.
Main power source supply portion of the DC power-supply system busbar as this system device, by high direct voltage 600VDC or higher
Voltage constitute, high voltage power supply is by dynamic lithium battery (pure electric vehicle system) or double electric systems (super capacitor+dynamic lithium battery) structure
Pass through the direct-current high-voltage system in series of single battery, core main electricity of the power supply as this control device at, battery pack
Source, this power supply are converted into the required AC power of marine system by inversion and processing.
In order to solve the moment of energization since the short circuit for moment occur caused flow problem, digitial controller to be connected with preliminary filling
Electric equipment system and device should be realized using pre-charge resistance with charging system device, be controlled, be pressed by the coordination of digitial controller
Sequence conducting release unit, completes the ramp input for starting the soft start and voltage of moment, so as to avoid DC-to-AC converter
Impact, while avoid again power end export instantaneous short circuit cause high current.
In voltage ramp ascent stage, since inverter is an intrinsic device, input characteristics has stable feature,
Therefore, the slope that voltage rises is previously having been predicted and constant, exactly there is this characteristic, can be exhausted by input terminal
Edge monitoring device tests the slope of voltage acclivity, when changing, can monitor the insulation damage of system
It is bad, to make necessary processing.
Inverter is the device cell of power supply DC communication transformation, is responsible for, by DC voltage, being converted into exchange 380V voltages,
From the angle of electrical characteristic, for a frequency is fixed, the fixed frequency-converter device of output voltage is when being set to 50HZ
System is just no longer implemented to adjust, and output frequency is stablized in this parameter, and the intrinsic output voltage and frequency of generator are similar to.
Due to inverter be by high order copped wave frequency conversion obtain, in power supply containing with abundant higher hamonic wave at
Part, if directly outputting it, the damage of equipment certainly will be caused, therefore, in present embodiment also set up sine wave processing unit,
Its higher hamonic wave will be filtered out, has effects that repair to power supply.Its basic function of sine wave processing unit is reactor function, is allowed
Power supply filters out part higher hamonic wave so that the ripple factor of power supply takes a favorable turn, and protects electrical equipment.
Digitial controller is also associated with break-make protection switching device, and break-make protects switching device monitoring that output power goes out
When now overload or power grid have great fluctuation process, it will make quick response processing, i.e. cut-out output under the control of digitial controller.
Digitial controller is also associated with boat-carrying customer equipment load, this part is that the required electricity consumption configured of conventional ship is set
It is standby, since the power supply of the three-phase four-wire system of use exports, the existing 380V of this power supply system, while having 220V again, to meet
Different purposes demands.
By the supply unit of load matched, power has certain surplus, to ensure that the electricity consumption of whole ship is stablized.With
Electric initial need to power on, and open low-voltage control power, then close main electricity, and system can enter automatic management operating and control
State.Close a floodgate moment into line precharge management and control, Insulation monitoring, under the premise of meeting performance parameter, load switch part unicom,
Under the premise of power meets design parameter, system enters stable operation, and power supply normally exports.In the system of stable operation,
Master controller mainly monitors the voltage and frequency of output, ensures the normal operation under rating index parameter.
The present apparatus can obtain the power of 10~500KW in the power configuration of power supply, conventional adaptation situation 10~
50KW or so, therefore, the complete demand that can cover serial ship, the frequency of power supply can be 50HZ~200HZ, conventional adaptation
Situation is 50HZ, therefore also can meet demand.Voltage class is consistent with traditional power supply parameter, and therefore, the present apparatus provides ship
The power supply of oceangoing ship routinely applied, the perfect distribution of pure electric vehicle ship.From the condition actually used at present, it is only necessary to by the electricity of whole ship
Source system demand power provides, this power-supply system need to only configure the DC-to-AC converter of suitable power capacity, then be carried out with the present apparatus
Combination application, system are just able to perfect.
