In this embodiment, comprising: the electric power arranging multiple electrical storage devices 101 as electric power providing source, substation 102 along route and possess electrical storage device and substation both sides provides equipment 103; Electric power is accepted via stringing 104 and the vehicle 105 of advancing from these electric power providing source; The electric power management system 108 of equipment 101 ~ 103 is provided with each electric power of management.
In the Railway System of this structure, by electrical storage device, electric power management system 108 judges that system 112, electric power auxiliary judgement system 113 and electric power assist decision systems 116 to form.
Electrical storage device judges that system 112 obtains representing whether vehicle location, car speed and vehicle are in the information of vehicles 109 of the vehicle-state power operation, in inertia force operation or in braking from vehicle 105, according to from the electric power providing source location information 111 obtained the data bank 110 providing the position of equipment 103 to manage as the electrical storage device 101 of electric power providing source, substation 102, electric power, determine that carrying out electric power from the equipment with which electrical storage device to stringing assists.
Electric power auxiliary judgement system 113 carries out whether to carry out the auxiliary judgement of electric power to vehicle 105 according to information of vehicles 109, and based on judging the 1st judged result 114 of system 112 and the 2nd judged result 115 from electric power auxiliary judgement system 113 from electrical storage device, judge which electric power providing source to carry out electric power to vehicle 105 from assists.
The electric power being sent to electrical storage device 101 by electric power being assisted the judged result 117 of decision systems 116 or possessing electrical storage device provides equipment 103, thus the electric power carried out from electrical storage device provides.
Fig. 2 illustrates that electrical storage device judges the concrete treatment scheme of system 112.
In step 201, based on current vehicle location, according to apart from vehicle order from the near to the remote, the electric power providing source possessing electrical storage device is classified, from nearest position, is set to 1,2 in order ... n, and enter step 202.
In addition, if the distance between vehicle with electrical storage device is too separated, power loss then owing to causing via long stringing becomes large, in addition, the possibility that other vehicles are just carrying out regenerative brake betwixt also uprises, so arrange apart from upper restriction the electric power providing source possessing the electrical storage device that will search.
In step 202., if K (searching ID)=1, step 203 is entered.
In step 203, judge that the SOC (electric power storage state) of electric power providing source (K) can carry out the state that electric power provides, provide if electric power can be carried out, then enter step 204, if electric power can not be carried out to be provided, then enter step 205.
In step 204, output command is sent to electric power providing source (K).Leave it at that.
In step 205, the K of the search ID as electric power providing source is set to (K+1), enters step 206.
In addition, in step 206, judge whether the upper limit (n) of the K > electric power providing source of the search ID as electric power providing source is set up, if K exceedes the upper limit of electric power providing source, the electrical storage device not existing and can carry out electric power and provide then is provided, and ends process, if K does not exceed the upper limit of electric power providing source, then turn back to step 203, continue to search the electrical storage device that can carry out electric power and provide.
By above process, can judge that system 112 calculates to apart from vehicle recently and can carry out the 1st relevant judged result 114 of electrical storage device that electric power provides by electrical storage device.
Fig. 3 illustrates the concrete treatment scheme of electric power auxiliary judgement system 113.
In step 301, judge whether vehicle-state is during power runs, if in power operation, then enter step 302, in running, then enters step 304 if not power.
In step 302, judge whether the car speed be included in car status information has exceeded V/f terminal velocity, when having exceeded, having entered step 303 and carrying out output request.
On the other hand, if car speed is below V/f terminal velocity, then enter step 304, do not carry out output request, end process.
In addition, so-called V/f terminal velocity, refers to that the stringing voltage degree of will speed up by carrying out the state before electric power is assisted by electrical storage device remains fixing and terminal velocity that is that obtain.
Fig. 4 illustrates that electric power assists the concrete treatment scheme of decision systems 116.
In step 401, judge, between determined electric power providing source and vehicle, have the electric power providing source invariably possessing electrical storage device and Jin Shi substation, if there is no the electric power providing source of Jin Shi substation, then enter step 402, if the electric power providing source of You Jinshi substation, then enter step 403.
In step 402, send the electrical storage device electric discharge of the electric power providing source that instruction makes to meet, end process, in step 403, owing to not making to carry out discharging so do not send instruction from the electrical storage device of electric power providing source.Leave it at that.
By above process, by vehicle being power operation and having exceeded V/f terminal velocity, from ground electrical storage device release electric power, thus stringing voltage can be promoted.
Such as, as shown in Figure 5, if the car speed under setting reference voltage is as α, the car speed after acceleration is β, and establishes stringing voltage is promoted to reference voltage × beta/alpha, then the acceleration capability of vehicle brings up to pattern a ' from pattern a.
Railway is determined due to schedule, so by improving acceleration capability, the inertia force time can be caused to increase, therefore, it is possible to realize energy-conservation.Use Fig. 6 and Fig. 7 illustrates the state all the time when applying this control.
As simple example, the route between Fig. 6 supposes AT STATION exists the situation of 2 electric power providing source 1 and 2 respectively with electrical storage device and the electric power providing source 3 be only made up of substation.
In addition, Fig. 7 establishes 1 train to advance on the route of Fig. 6, and the state all the time when the control applying the present embodiment is shown.
From on the relation in [time m-speed], [time m-V/f speed judge], [time m-power run judge], [time the m-distance with electric power providing source], [time m-electric power providing source 1 instruction], [time m-electric power providing source 2 instruction], the SOC of m-electric power providing source 1 [time], the SOC of m-electric power providing source 2 [time], [time m-vehicle stringing voltage] is shown in order.In addition, about solid line, in the relation in [time m-speed], the situation of the control employing the present embodiment is represented by solid line, represented the situation of the control not using the present embodiment by dotted line, but both time integral values are set to fixing, so that schedule does not change.
Temporally carry out Region Segmentation to be described to these diagram of curves.
Time zone A represents that vehicle carries out power operation from station and speed is the situation in the region of below V/f terminal velocity.In this case, if according to the treatment scheme of Fig. 3, then do not provide request to the electric power of electrical storage device, vehicle carries out controlling identical action with not using.
Then, if car speed is more than V/f terminal velocity, then time zone B is transferred to.
In time zone B, because car speed has exceeded V/f terminal velocity, so according to the treatment scheme of Fig. 2, the electric power providing source 1 being only electrical storage device is nearer apart from vehicle location than the electric power providing source 2 possessing electrical storage device and substation both sides, in addition, the SOC of the electrical storage device of electric power providing source 1 is also enough, according to the treatment scheme of Fig. 4, electric power providing source 1 is nearer than the electric power providing source 3 of Jin Shi substation, so send instruction to electric power providing source 1.
In addition, according to the treatment scheme of Fig. 3, due to be power run in and car speed has exceeded V/f terminal velocity, so carry out the request to electric power providing source.
Thus, carry out electric discharge instruction to electric power providing source 1, the stringing voltage rise of vehicle, power drive ability rises, and accelerates to be enhanced.But be accompanied by this, the SOC of electric power providing source 1 reduces gradually.
Then, run if vehicle enters inertia force, be then transferred to time zone C.
In this case, according to the treatment scheme of Fig. 3, do not carry out the request to electric power providing source.Thus, the SOC of electric power providing source 1 and electric power providing source 2 does not change.Then, run if vehicle enters power again, be then transferred to time zone D.
In time zone D, illustrate that vehicle carries out power operation again and speed has exceeded the situation of V/f terminal velocity.In this case, according to the treatment scheme of Fig. 3, carry out the request to electric power providing source.
In addition, according to the treatment scheme of Fig. 2, because electric power providing source 2 is nearer apart from vehicle location than electric power providing source 1, SOC is also enough, so carry out electric discharge instruction to electric power providing source 2, but because electric power providing source 3 is nearer than electric power providing source 2, so do not carry out the electric discharge from electric power providing source according to the process of Fig. 4.Thus, power drive ability is identical with without controlling.Then, if electric power providing source 2 becomes nearer than electric power providing source 3, then time zone E is transferred to.
In time zone E, illustrate that vehicle carries out power operation again and speed has exceeded the situation of V/f terminal velocity.In this case, according to the treatment scheme of Fig. 3, carry out the request to electric power providing source.In addition, according to the treatment scheme of Fig. 2, electric power providing source 2 is nearer apart from vehicle location than electric power providing source 1, SOC is also enough, according to the treatment scheme of Fig. 4, electric power providing source 2 is nearer than the electric power providing source 3 of Jin Shi substation, so carry out electric discharge instruction to electric power providing source 2, the SOC of electric power providing source 2 reduces gradually.In addition, the stringing voltage rise of vehicle.Thus, power drive ability rises, and accelerates to improve.Then, if vehicle enters inertia force, then time zone F is transferred to.
In time zone F, vehicle is in inertia force operation.In this case, according to the treatment scheme of Fig. 3, do not carry out the request to electric power providing source.Therefore, the SOC of electric power providing source 1 and electric power providing source 2 does not change.Then, if vehicle enters braking, then time zone G is transferred to.
In time zone G, H, vehicle is in braking.In this case, control electric power providing source to charge respectively.
By above process, by discharging electric power from ground electrical storage device, the effect of the stringing voltage that gets a promotion, stringing voltage when running by keeping power higher, while observing schedule, reduces power time of run, increase inertia force traveling time, thus can realize energy-conservation.
[embodiment 2]
Then, Fig. 8 illustrates the system architecture of embodiment 2.The point different from embodiment 1 is, comprises the stringing voltage provided to this vehicle in information of vehicles 801, and electric power auxiliary judgement system 802 changes judgement according to this stringing voltage.
The process of electric power auxiliary judgement system 802 is illustrated by Fig. 9.
In step 301, judge whether vehicle-state is that power runs driving, if "Yes", enters step 302.If "No", enter step 304.
In step 302, judge whether the speed be included in car status information has exceeded V/f, if "Yes", enters step 901.If "No", enter step 304.
In step 901, judge that whether stringing voltage is less than stringing voltage threshold α.If "Yes", enter step 303.If "No", enter step 304.
Send the request of output in step 303.In addition, the request of output is not sent in step 304.Leave it at that.
In addition, stringing voltage threshold α in step 901 is arbitrary value, importantly, near other trains when fully not obtaining the effect produced because of the electric discharge from electrical storage device or in regenerative brake are in, be set as that the braking force not making to produce because of regeneration reduces, such as, the underloading of reference voltage or vehicle also can be used to start voltage.In addition, be not fixing in route entirety, such as also can according to the density of schedule and temporally, each electric power provides equipment to change α.
By implementing this control, thus realize the equalization of stringing voltage.In addition, due to the running also equalization of electrical storage device, so also can capacity be suppressed.
