Based on track crane DC power-supply system set forth above, the application also proposes a kind of track crane direct current supply method,
As shown in figure 3, including the following steps:
Step S21: the track crane job instruction that Terminal Operating System is sent is received.
Terminal Operating System sends track crane job instruction to each track crane.
Step S22: current working track crane job instruction is subjected to priority ranking.
For multiple stockyards of an automatic dock, have more set track crane DC power-supply systems, every set track crane is straight
The track crane that stream power supply system is responsible for setting number provides direct current supply, the power supply management of every set track crane DC power-supply system
Module obtains the track crane job instruction of the multi-section track crane in this system from Terminal Operating System, and according to setting rule to this
A little track crane job instructions carry out priority level sequence.
Step S23: current working track crane job instruction is executed according to priority ranking.
Power supply management module in track crane DC power-supply system is carrying out priority row to all track crane job instructions
After sequence, control executes current working track crane job instruction according to priority ranking.
Step S24: judge whether the workload of track crane exceeds rated load.
In current working, total track crane workload in computing system, judge current working workload whether
More than the rated load of setting, namely whether be more than system maximum working load, if so,
Step S25: the control other track crane job instruction delayed execution of low priority.
In the workload maximum of current working, the other track crane job instruction delay of control low priority is executed, really
The rated load that the sum of working power being currently running is no more than track crane DC power-supply system is protected, it can be maximum
Reduction system coincidence factor, reduces the installed capacity of whole system, realize using lesser direct current installed capacity to
More track crane power supplies, have saved installation cost.
It is above-mentioned, the energy in system is distributed rationally by power supply management module, while having saved installation cost, moreover it is possible to
It enough realizes that the energy regenerative between multi-section track crane is shared and utilizes, the efficiency of energy utilization of track crane is improved, so that the application proposes
Track crane DC power-supply system energy conservation and operating cost on have advantage.Specifically, after step s 21, also executing step
Rapid S26: control will generate the track crane job instruction of energy feedback and can not generate the track crane operation of energy feedback
Instructing combination executes.
Cart, trolley, the raising operating mechanism of track crane take electricity when accelerating and traveling at the uniform speed from DC power-supply system,
In deceleration and lifting mechanism decline operation to DC power-supply system feedback electric energy, therefore, the track crane direct current in the application is supplied
Electric system, use will generate the track crane job instruction of energy feedback and can not generate the track crane operation of energy feedback
The mode that instructing combination executes, avoids the track crane job instruction that can generate energy feedback from being individually performed, also avoids back
The waste of energy regenerative amount guarantees that track crane can use system feedback to greatest extent so that feedback energy is applied to current working
Electric energy, saved the power grid energy.
The direct current supply side in track crane DC power-supply system the application proposed with a specific embodiment below
Method is described in detail.
Assuming that the cart of 8 track cranes in every set track crane DC power-supply system, raising, trolley are different in a certain period
The different operating condition of operating status composition whole system, there is different power demands in each mechanism under different loads；Such as
Relatively common operating condition: 8 track cranes of 4 heap blocks have 4 carts to accelerate work simultaneously, have 2 cart steady operations, there is 2
Platform raising is in unloaded operation, and among these, cart peak power is 849KW and steady state power is 343KW, peak when raising zero load
Value power is 464KW and steady state power is 376KW, and auxiliary body's power is 20KW, then can calculate 8 track cranes most
It is high-power are as follows:
Pg=(849+20)*4+(343+20)*2+(464+20)*2=5170KW ;Calculate the steady state power of 8 track cranes are as follows: Pw=
(343+20)*4+(343+20)*2+(376+20)*2=2970KW。
TOS(Terminal Operating System) by track crane job instruction be first sent to track crane DC power-supply system for fulgurite
Module is managed, track crane job instruction refers to an instruction sequence group, when one group of instruction execution, power supply management module 1) it can basis
Instruction sequences control the response time that 8 track cranes execute the instruction of respective rail crane operations, 2) by current 8 tracks crane operation work
The job instruction for the mechanism for needing to run in condition optimizes combination according to priority, 3) control first carry out that priority is high (can be with
According to handling ship instruction highest, transmitting-receiving case instruction are taken second place, stockyard varus smashes and instructs minimum principle) track crane mechanism action refer to
Enable, 4) time that track crane executing agency acts is controlled according to priority, guarantee the sum of mechanism power being currently running
No more than the rated load that DC power-supply system allows, such as exceed rated load, then controls the low job instruction delay of priority
It executes；5) control will generate the track crane job instruction of energy feedback and can not generate the track crane operation of energy feedback
Instructing combination executes；In 4 heap blocks, 8 track cranes in a set of track crane DC power-supply system, when wherein several track loop wheel machines
Structure is in energy feedback state when being in deceleration or lifting mechanism decline state, the feedback electric energy of generation can be by public straight
It flows bus to use for other track crane mechanisms, so as to reduce the installation general power of direct current of ground power supply unit, reduces installation
Capacity, and guarantee the electric energy that can use other track crane feedbacks when certain track crane operation to greatest extent, to reduce
The installation general power of DC power-supply system.
The coincidence factor referring to shown in following table one calculates, and the track crane direct current supply method proposed according to the application is excellent
It is 0.65 that 8 track cranes after change, which select coincidence factor:
Table one
| Track crane quantity | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
