Bank does not interrupt switch mode and bank and ship do not interrupt switch mode these three or it is arbitrary two kinds therein.
Wherein, it is that a kind of operating mode usually used in the prior art is cut in interruption as its name suggests to interrupt switch mode
In mold changing formula, need to interrupt the power supply to ship electrical equipment in the handoff procedure of power supply, therefore the pattern is usually only
Applied to the lower ship of some power grades.
Other two kinds of operating modes, which belong to, does not interrupt switch mode, that is, and allow ship electricity and bank electricity to synchronize simultaneously vehicle first,
Simultaneously to ship power supply for electrical equipment, respective output power is then adjusted, until needing continued power in the follow-up process
When the output power of one side reaches marine vessel applications demand, other side power supply is turned off.Since synchronous and vehicle cannot be carried out arbitrarily,
Must be could be carried out under the output phase unanimous circumstances of ship electricity power supply and shore electric power, therefore ship electricity or bank electricity control
Equipment needs to monitor the output of another party's power supply, to synchronize Combine control when meeting condition for parallel connection.
Ship and bank do not interrupt switch mode be exactly dominated by ship electricity power control unit and vehicle switch mode.At some
In the bank electricity scene of harbour, ship may be caused not prop up because of the reasons such as bank side or the cotton covered wire road of shipboard, interface parameters

Bank electricity control module corresponding with mode selection command is selected and called from preset a variety of bank electricity control modules,
To realize that bank electricity and ship electricity include to the power switching of ship power load with corresponding operating mode：
Judge whether the current state of ship is the state of beaching；
If so, period control module of beaching corresponding with mode selection command is called, so as to corresponding Working mould
The power supply of ship power load is changed to bank electricity by formula by ship cutting；
If it is not, ship offshore period control module corresponding with mode selection command is then called, so as to corresponding Working mould
The power supply of ship power load is switched to ship electricity by formula by bank electricity.
Specifically, what is be directed to due to shore electric power product in the prior art is mostly power switching mistake when ship pulls in shore
Journey, and the ship offshore period then lacks scientific and effective control.Therefore, the shore electric power controlling party that the embodiment of the present application is provided
Method on the basis of the above embodiments, also while being related to beaching and the control process under two states of ship offshore, to
The whole process of ship entry and departure from port, the use of more convenient user can be completely applied to.
Wherein, will be stopped at harbour in a period of time due to ship after the state of beaching, need at this time will be
The power supply of ship power supply for electrical equipment is changed to bank electricity by ship cutting.And similarly, since ship will go out after ship offshore state
Port is navigated by water, and therefore, it is necessary to will be that the power supply that ship power load is powered is switched to ship electricity by bank electricity.
As for the judgment method to ship current state, it can refer to flow chart as shown in Figure 2 and carry out.
Step 21：Obtain finishing switching flag bit；Wherein, finishing switching flag bit is set to 1 after the completion of each switching.
Specifically, in the judgement algorithm provided herein to ship status shown in Fig. 2, it is provided with finishing switching mark
Will position and ship status counter the two variables.Wherein, finishing switching flag bit is intended to indicate that whether current time completes
Primary complete power switching process：1 indicates just to have completed once to switch；0 indicates that current handoff procedure does not complete also.Ship
Oceangoing ship state counter can be come into operation in shore electric power system initial for distinguishing pulling in shore and offshore state for ship
Moment sets initial value to ship status counter：1 indicates state of beaching；0 indicates ship offshore state.
Step 22：Judge whether finishing switching flag bit is 1；If so, entering step 23；If it is not, then entering step 24.
Step 23：Ship status counter is added 1, and finishing switching flag bit is reset to 0；Enter step 24.
Wherein, ship status counter is set as 1 in the initial value for initial time of beaching.
Specifically, after the completion of each power switching, finishing switching flag bit can be with automatic assignment for 1.So working as detection
To finishing switching flag bit be 1 when, mean that the state of ship just completes one-shot change, that is, may be just by the shape that pulls in shore
State becomes the offshore state that will be carried out, or becomes the state of pulling in shore that will be carried out from offshore state, then at this time can be in step
The ship status counter for characterizing ship status is also added 1 in 23, and finishing switching flag bit is reset to 0, so as in next time
When finishing switching again by finishing switching mark position be 1.
Step 24：Judge whether ship status counter is 2；If so, entering step 25；If it is not, then entering step 26.
Step 25：Ship status counter is reset to 0；Enter step 26.
Specifically, in order to avoid making its numerical value become always the accumulation operations of ship status counter in step 23
Change, therefore the value of ship status counter can be enabled to continue to be limited in 0 and 1 two state by the reset operation in step 25,
Judge so as to enter step 26 pairs of ship status.
Step 26：Judge whether ship status counter is 1；If so, entering step 27；If it is not, then entering step 28.
Step 27：Judgement ship enters state of beaching.
Step 28：Judgement ship enters ship offshore state.
On the basis of the above embodiments, as a kind of preferred embodiment, when mode selection command is that simultaneously bank does not interrupt ship
When switch mode instructs, realize that bank electricity and ship electricity include to the power switching of ship power load with corresponding operating mode：
Obtain the output data of shore electric power；
Judge whether the fluctuation situation of the output data of shore electric power meets default surging condition；
If so, judgement and stopping switch be closed under the action of ship electricity power control unit and complete bank electricity and ship electricity
Synchronous and vehicle then utilizes the real output of pre-set control algorithm adjustment shore electric power, so that the reality in shore electric power is defeated
Go out power satisfaction when presetting from spoke part, open command is sent from ship electricity power control unit to from stopping switch；
Wherein, when the current state of ship is to beach state, and stopping switch switchs for bank side, is shipboard from stopping switch
Switch is preset and increases to power given value from the real output that spoke part is shore electric power；
When the current state of ship is ship offshore state, and stopping switch switchs for shipboard, is switched for bank side from stopping switch,
It presets and is decreased to power lowest threshold from the real output that spoke part is shore electric power；
The first end of bank side switch and the output end of shore electric power connect, and second end is connect with ship power load；Shipboard
The first end of switch is connect with the output end of ship electricity power supply, and second end is connect with ship power load.
Specifically, in bank electricity scene, the switching between bank electricity and ship electricity is typically all to be opened by bank side switch and shipboard
The break-make of pass and realize.Wherein, bank side switch is the switch being connected between shore electric power output end and ship power load,
Shipboard switch is the switch being connected between ship electricity power output end and ship power load.Also, described bank side switch and
Shipboard switch is specifically as follows the switching devices such as breaker.Usually, the bank electricities equipment such as bank side switch and shore electric power can be arranged
In special bank electricity electronic box.
In ship and bank do not interrupt switch mode, ship electricity is synchronous with bank electricity and vehicle is by means of ship electricity power control unit
It realizes, so, shore electric power control device itself needs a set of detection method to detect when to have carried out synchronous and vehicle, so as to
Complete subsequent output power adjustment and switching.In order to coordinate ship electricity power control unit to complete power switching, the application
The shore electric power control method that embodiment is provided according to and the shock vibration phenomenon that can be formed of vehicle moment, do not interrupted in ship and bank
The method that simultaneously vehicle situation is detected by shore electric power output pulsation is used under switch mode, so as to confirm simultaneously vehicle in time
The closure of switch, and then the adjustment to output power is continued to complete, it is disconnected from stopping switch to be carried out when meeting from spoke part
Open operation.
Wherein it is possible to distinguish the default surging condition under the default surging condition and ship offshore state under the state of beaching
It is configured；For example, the default surging condition under state of beaching specifically could be provided as " the active output current of shore electric power
Increase to preset active output current fluctuation upper limit value "；And the default surging condition under ship offshore state can be specifically set
For " the idle output current of shore electric power and the absolute value of the difference of its average value are more than preset idle output current fluctuation amount
Threshold value ".Certainly, those skilled in the art can also using other embodiment shore electric power output pulsations default surging condition come pair
And car state is detected, this embodiment of the present application is not limited thereto.
After judgement and stopping switch closure, you can to adjust the reality output work(of shore electric power using pre-set control algorithm
Rate, in order to make it meets from spoke part.Since simultaneously vehicle moment ship electricity is consistent with the output of bank electricity, after simultaneously vehicle, from vehicle
Also need to a transition adjusting stage before, so as to will be from vehicle power supply output power is gradually lowered and will be alone
Output power is increase gradually to setting value by the power supply of power supply.It is actually main to the control of output power in the transient process
If being realized by the control to electric current, described pre-set control algorithm voluntarily can be selected and set by those skilled in the art
Realization is set, such as common PI current loop controls can be used.During carrying out output power output current control in other words,
The output electrical angle of ship electricity power supply when generally also needing to use simultaneously vehicle, also the output electrical angle of shore electric power therefore can
To obtain output electrical angle of the shore electric power in simultaneously vehicle by calculating：
θ1=arctan (Uβ/Uα)；
Wherein, θ1For output electrical angle of the shore electric power in simultaneously vehicle；UαExist for output voltage of the shore electric power in simultaneously vehicle
α components in α β coordinate systems；UβFor β component of output voltage of the shore electric power in simultaneously vehicle in α β coordinate systems.
In addition, it is above-mentioned switch mode do not interrupted to ship and bank introduce content on the basis of, can also be further the work
Switching control process under operation mode divides the stage, and is shown by display device, in use more so as to user
Add and grasps current control process clearly.For example, the process before the synchronous and vehicle situation in judgement early period can be known as
" free time " stage；And after it determined and stopping switch is closed, claim to enter " and vehicle " stage；And shore electric power will be adjusted
Output power and the process disconnected from stopping switch are known as " power transfer " stage.Certainly, those skilled in the art can also use
Other stage division methods, this embodiment of the present application is not limited thereto.
It should be noted that for the state of beaching, described " output data for obtaining shore electric power " refers in bank electricity
Power supply is obtained in the case of having had been started up, and otherwise the step will lose meaning.Certainly, the startup of shore electric power needs one
A process usually could be provided as constant speed startup, even its given output frequency, given output voltage etc. are linearly increasing.This
Field technology personnel voluntarily can select and be arranged, and this embodiment of the present application is not limited thereto.
As for switch mode is interrupted, corresponding processing procedure is then relatively simple.When user has input interruption switch mode
After instruction, if it is determined that ship current state is state of pulling in shore, then it may determine that whether shipboard switch is already off, if so, can
Onshore side switch sends close command, i.e., enable bank electricity again after ship electricity stops power supply powering for ship power load；If it is determined that
Ship current state is offshore state, then can be switched with onshore side and send open command, so that ship electricity power control unit is being examined
It measures to switch to shipboard after bank side switch disconnects and sends close command, i.e., enable ship electricity again after bank electricity stops power supply using for ship
Electric loading is powered.
Due to interrupting the no simultaneously processes such as vehicle of switch mode, divided stages are fairly simple, shape of either beaching
State or ship offshore state all can be considered only " free time " this stage.
On the basis of the above embodiments, as a kind of preferred embodiment, bank and ship do not interrupt switch mode include bank simultaneously
Ship does not interrupt automatic switchover mode and bank and ship does not interrupt manual switching pattern.
Specifically, bank and ship in the shore electric power control method that the embodiment of the present application is provided do not interrupt switch mode again
It can specifically include bank and ship does not interrupt automatic switchover mode and bank and ship does not interrupt manual switching pattern.Wherein, bank and ship be not
Interrupting automatic switchover mode can be after the completion of a stage in simultaneously vehicle handoff procedure automatically into next stage, and bank is simultaneously
It is the phase just executed after receiving dependent instruction input by user in simultaneously vehicle handoff procedure that ship, which does not interrupt manual switching pattern then,
Step is answered, but the core processing thought of the two is consistent.
On the basis of the above embodiments, as a kind of preferred embodiment, when mode selection command is that simultaneously ship does not interrupt bank
When automatic switchover mode instructs, the mistake of bank electricity and ship electricity to the power switching of ship power load is realized with corresponding operating mode
The step flow of journey is as shown in figure 3, include：
Step 31：Obtain the output data of shore electric power.
Wherein, it needs to carry out in any case as previously mentioned, synchronizing simultaneously vehicle, i.e. the output data of ship electricity and bank electricity
Unanimously, otherwise, grid-connected by force to be likely to initiation electrification.Therefore, it is necessary first to obtain the output data of bank electricity and ship electricity
To judge condition for parallel connection.Specifically, output data described in the application is specifically as follows output voltage, output frequency
Rate and output electrical angle.
As previously mentioned, obtaining shore electric power output data certainly in the state that shore electric power has had been started up.It is true
On, for ship i.e. by the situation of offshore, shore electric power for ship power load due to powering always, so being certainly in fortune
Row state.And for the situation that ship will pull in shore, then it needs to pre-actuate shore electric power.It should be noted that shore electric power can
Under in such a way that specific works are in voltage and frequency separation, i.e., output voltage can individually receive shore electric power with output frequency
The control of control device.
Specifically, in the start-up course of shore electric power, for the purpose of smooth transition, the output of shore electric power can be enabled
Voltage and output frequency are first from zero linear increase, then stablize near final setting value.As for the output electric angle of shore electric power
Degree, then can be updated calculating using its relationship between output frequency：
The π of Δ θ=2 fT；
θ2=θ2′+Δθ；
Wherein, Δ θ is variable quantity of the output electrical angle of shore electric power during interval time T；F is the defeated of shore electric power
Go out frequency, it should be noted that as previously mentioned, output frequency f here is variation in early period；θ2For current time bank electricity electricity
The output electrical angle in source；θ2' it is the output electrical angle for updating preceding shore electric power.
Step 32：The output data of ship electricity power supply is obtained into horizontal lock to ship electricity power supply.
Specifically, the output of ship electricity power supply can be locked by single synchronous coordinate system software phase-lock loop SSRF-SPLL
Phase, and then obtain the output data of ship electricity power supply.
In addition, in order to ensure locking phase success to get to ship electricity power supply output data accuracy, can be to locking phase knot
Fruit is judged：The output voltage for the ship electricity power supply that locking phase obtains is converted through three phase static to two rotating coordinate systems, is obtained
Its d shaft voltage component Ud and q shaft voltage component Uq, and judge Uq<It is (Ud/3) whether true, if so, then illustrate locking phase success,
Because the q shaft voltage components Uq after locking phase success is smaller.
Step 33：Judge the difference of the output data of shore electric power and the output data of ship electricity power supply whether in preset range
It is interior；If so, entering step 35；If it is not, then entering step 34.
Specifically, after getting the output data of ship electricity power supply, so that it may with to whether meeting condition for parallel connection and sentencing
Break.If condition for parallel connection meets, 35 execution and vehicle operation can be entered step；If condition for parallel connection is unsatisfactory for, need to enter
Step 34 adjusts the output of shore electric power.
As previously mentioned, in order to ensure the satisfaction of synchronous condition for parallel connection, i.e. shore electric power is consistent with the output of ship electricity power supply, can have
A preset range is arranged in body, can determine that synchronous condition for parallel connection meets when the difference of the two output is within preset range.When
So, described preset range can voluntarily be selected to set by those skilled in that art according to practical situations, and the application is real
Example is applied to be not limited thereto.
Step 34：The output data of shore electric power is adjusted；Enter step 33.
For the output voltage and output frequency of shore electric power, its given value need to be only adjusted to the phase one with ship electricity power supply
Cause.And for the output electrical angle of shore electric power, then it needs to carry out closed loop after making difference with the output electrical angle of ship electricity power supply
Control.
Specifically, in the output electrical angle θ for getting shore electric power2With the output electrical angle θ of ship electricity power supply3Later, it can incite somebody to action
The difference θ of the twoerrElectrical angle increment of adjustment Δ θ is calculated in input controllerPI, such as the progress of PI controllers specifically can be used
Proportional integration operation；Then again to the output electrical angle θ of shore electric power2It is adjusted, until θerrAlso meet condition for parallel connection：
Wherein,For the output electrical angle of the shore electric power after adjustment.
Step 35：Close command is sent to simultaneously stopping switch.
As previously mentioned, under the state of pulling in shore, and stopping switch, that is, bank side switch；Under offshore state, and stopping switch, that is, shipboard
Switch.After condition for parallel connection meets, you can be closed simultaneously stopping switch, realize simultaneously vehicle.
It is similar that switch mode is not interrupted with ship and bank, bank and ship does not interrupt automatic switchover mode and can also be divided into multiple ranks
Section.Wherein, before step 32, it all can be described as " free time " stage；The corresponding process of step 32~step 34 is properly termed as " phase
Adjustment " the stage；And step 35 then corresponds to " and vehicle " stage.
Manual switching pattern is not interrupted for bank and ship, there is and bank and ship not interrupt automatic switchover mode identical respectively
A stage.Unlike, each stage is just carried out receiving dependent instruction input by user, for example, it is defeated to work as user
After having entered phase adjustment instruction, bank and ship do not interrupt the shore electric power control device under manual switching pattern just and can enter default
" phase adjustment " stage, that is, start execute step 32~step 34.The bank and ship being hereinafter previously mentioned do not interrupt automatic switchover
Other states of pattern are similarly similar, and the similar content in the part hereinafter just repeats no more.
Step 36：The real output of shore electric power is adjusted using pre-set control algorithm.
After executing the step for 35 i.e. completion " and vehicle " stage, you can enter next stage " power transfer ".Due to
And vehicle moment ship electricity is consistent with the output of bank electricity, therefore, and vehicle after, from vehicle before also need to a transition adjusting stage,
So as to will be from vehicle power supply will export gradually lower and will solely self-powered power supply output is increase gradually to set
Value.The transient process as so-called " power transfer " stage.
It should be noted that the power that bank and ship do not interrupt in switching (including automatic switchover and manual switching) pattern shifts
Concrete operation method with the power transfer in other patterns is identical.In the power transfer process of these types of operating mode
In, it is worth mentioning at this point that, it is also necessary to pay attention to the inverse probability output problem of bank side power supply.So-called inverse probability output, that is, refer to ship electricity
The output power of power supply, which pours in down a chimney, is equivalent to the output power of bank side power supply into bank side power supply as negative value.Therefore, it can monitor in real time
The output power factor of bank side power supply, and the output electrical angle of shore electric power is adjusted according to its output power factor in real time, make it
Forward power is exported, is shut down to prevent busbar voltage lifting or even separating brake caused by non-return Power Phenomenon.Wherein, output power because
Several calculation expressions are：
Wherein, pfacFor output power factor；IdFor output current dq coordinate systems d axis components；IqExist for output current
The q axis components of dq coordinate systems；IampFor the amplitude of output current.
Meanwhile in order to further prevent inverse probability, can also be shore electric power output current at the beginning of power transfering state
Suitable initial value and given value are set when the beginning.For example, the given value of the output current under state of beaching could be provided as most
Big given value：
Wherein, IdmaxrefFor watt current maximum given value；IqmaxrefFor reactive current maximum given value；PrefFor wattful power
Rate maximum given value；QrefFor reactive power maximum given value；UdrefFor active voltage given value；UqrefIt is given for reactive voltage
Value.Due to UdrefIt is the d axis components of voltage given value, UqrefIt is the q axis components of voltage given value, therefore, usually, can incites somebody to action
UqrefIt is specifically configured to 0, and by UdrefIt is set as the amplitude size of voltage given value.
Certainly, those skilled in the art can also voluntarily select setting initial value and given value according to practical situations,
This embodiment of the present application is not limited thereto.
Step 37：Judge whether the real output of shore electric power reaches to preset from spoke part；If so, entering step
38；If it is not, then entering step 36.
If being preset from spoke part as previously mentioned, the real output of shore electric power has reached, you can it is logical to enter step 38
Order is crossed to disconnect to realize from vehicle from stopping switch；Otherwise, then 36 can be entered step and continue with pre-set control algorithm adjustment bank electricity electricity
The real output in source, until it reaches and presets from spoke part.
Step 38：Open command is sent to from stopping switch.
When meeting after realize from vehicle from spoke part, " power transfer " stage also just finishes, i.e., this for cutting
It changes and just completes.Thus it can pull in shore automatically into next ship the/power switching process of offshore.
On the basis of the above embodiments, as a kind of preferred embodiment, in the output data and ship for judging shore electric power
The difference of the output data of power supply whether it is within the preset range, further includes：
If the difference of the output data of shore electric power and the output data of ship electricity power supply within a preset range, does not judge bank
Whether the phase sequence of power supply is consistent with the phase sequence of ship electricity power supply；
If it is not, frequency given value adjust instruction is then generated, to adjust the frequency given value of shore electric power and then to adjust bank
The phase sequence of power supply.
Specifically, since there is two kinds of phase sequences for AC three-phase, if the phase sequence of shore electric power and ship electricity power supply is inconsistent,
It cannot be satisfied the consistent condition for parallel connection of output data certainly.Therefore, when detecting that the phase sequence of the two is inconsistent, in the application
Bank and ship do not interrupt automatic switchover mode and can realize the online switching of phase sequence automatically, without changing U, V and W three-phase electricity
The mode of connection.Specifically, the positive and negative of frequency given value that shore electric power can be inputed to by modification is realized.Certainly, phase sequence
The purpose of switching is in order to realize synchronous and vehicle, so the operation was carried out before " and vehicle " stage.
In addition, in other several operating modes, shore electric power control method provided herein can also realize phase
Sequence checking process, also, the online switching of phase sequence, Huo Zhegen can also be specifically executed according to phase sequence switching command input by user
Instruction is kept to continue to keep current phase sequence according to phase sequence input by user.Due to the given output in shore electric power start-up course
What frequency inherently changed, therefore, if user is the phase sequence handoff functionality inputted in shore electric power start-up course, need
The positive and negative and size for giving output frequency is changed simultaneously；And if user is the phase sequence inputted after shore electric power stable operation cuts
Function is changed, then need to only change the positive and negative of given output frequency.
On the basis of the above embodiments, as a kind of preferred embodiment, power given value is and ship power load
The equal value of actual power consumption value.
Specifically, it is contemplated that may start suddenly on ship and run some powerful ship power loads, such as is empty
Press and pump class etc., the performance number that ship power load is actually consumed at this time can be flown up, and therefore, it is necessary to suitably bases
Practical situations adjustment " power transfer " power given value of shore electric power in the stage, to avoid the under-voltage of ship power load
Irregular operation.Specifically, power given value can be set to the value equal with the actual power consumption value of ship power load：
Wherein, P is the actual consumption active power value of ship power load；Q be ship power load actual consumption without
