Background technology
Subway regenerative braking feedback device in the way of inversion feed-back parallel network by underground engines skidding when produce it is many
Complementary energy is fed back to AC network, is following ground with low-carbon energy-saving, environmental protection, the reliable and stable, outstanding advantage that investment is low
The developing direction that iron regenerating braking energy absorbs.
Modularization subway regenerative braking feedback device scalability is good, and redundancy is high, is not interfered with during individual module failure
Other modules are normally run, therefore are particularly suited for this reliability requirement of electric power supply system for subway occasion higher.If but device
All modules put into operation simultaneously, and when local iron energy is smaller, each module is in small-power feedback running status, leads
Cause whole efficiency relatively low, so that controlling input and the excision of each module.During module is put into and is cut off,
Need to consider modules run time whether in a balanced way problem, it is to avoid the module having puts into operation for a long time, and some modules are long
Phase is in and exits state, so as to influence the overall service life of device.
The content of the invention
It is an object of the invention to provide a kind of intelligent dormancy of modularization metro braking feedback device and rotation control method,
The drawbacks of whole efficiency is relatively low when metro braking energy is smaller solving modularization subway regenerative braking feedback device, realizes dress
Whole efficiency is put to optimize and equalization of each module working time.
In order to realize the above object the technical solution adopted in the present invention is：A kind of modularization metro braking feedback device
Intelligent dormancy and rotation control method, when feedback device runs, metro braking energy size and mould according to real-time monitoring
Block running priority level, controls each module step -by -step switch or excision；When local iron energy increases, each module presses running priority level
Size puts into operation successively；When local iron energy reduces, each module is cut off successively by running priority level size.
Module running priority level calculating process is as follows：Module running priority level is stored by queue is ascending,
When each feedback device enters standby operation, running priority level highest module is deleted from head of the queue and is inserted into tail of the queue, so that
To new priority sequence.
The process of each module step -by -step switch is as follows：When it is standby switch to feedback run when, input priority be 1 module, and
The feedback power of the input module is calculated in real time；When input setting value of the feedback power more than the input module absorptive capacity,
Input priority is 2 module, and calculates total feedback power of two modules for having put into real time；When total feedback work(of two modules
When rate is more than the input setting value of two modules total absorptive capacity, input priority is 3 module, repeats said process, until throwing
Untill entering whole modules.
The process that each module cuts off step by step is as follows：When n module is run in feedback, its total feedback power is calculated in real time；
When excision setting value of total feedback power less than n-1 total absorptive capacity of module, the module that priority is 1 is cut off, and in real time
Calculate remaining n-1 total feedback power of module；When n-1 total feedback power of module always absorbs appearance less than (n-2) individual module
Amount 80% when, excision priority is 2 module, repeats said process, untill a remaining module；When direct current contact net
When voltage is less than the feedback threshold value for setting, last module is cut off, feedback device enters holding state.
The input setting value is 80%.
The excision setting value is 80%.
The intelligent dormancy of modularization metro braking feedback device of the invention and the iron kinetic energy in rotation control method base area
Amount size is put into and is cut off to module, it is possible to achieve the optimization of whole efficiency, by the setting of module running priority level,
During module step -by -step switch, running priority level module high first puts into, during module cuts off step by step, running priority level
Module high first cuts off, and so as to realize each module working time equalization, improves the overall service life of device.
Brief description of the drawings
Fig. 1 is overall logic figure of the invention；
Fig. 2 is the flow chart of module step -by -step switch process；
Fig. 3 is the flow chart that module cuts off process step by step.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the present invention.
It is as shown in Figure 1 intelligent dormancy and the rotation control method reality of modularization subway regenerative braking feedback device of the present invention
The overall logic figure of example is applied, as seen from the figure, when feedback device runs, metro braking energy size and mould according to real-time monitoring
Block running priority level, controls each module step -by -step switch or excision, it is to avoid all modules are in small-power feedback running status, from
And realize the optimization of device whole efficiency；When local iron energy increases, each module is thrown successively by running priority level size
Enter operation；When local iron energy reduces, each module is cut off successively by running priority level size.
The present embodiment module running priority level calculating process is as follows：Module running priority level is carried out by queue is ascending
Storage, when each feedback device enters standby operation, running priority level highest module is deleted from head of the queue and is inserted into tail of the queue,
So as to obtain new priority sequence.
As shown in Fig. 2 the process of each module step -by -step switch is as follows：
