Description
Technical field
The invention belongs to battery network technical fields, are related to a kind of restructural battery network energy control system, substation
System.
Background technique
As energy resource structure constantly adjusts, the electric system in China has obtained quick development, as weight in electric system
The component part wanted, the Stability and dependability of electrical secondary system is directly related to the stable operation of electric system in substation.For
Ensure that relay protection, communication equipment etc. operate normally, it is negative for electrical secondary system to be equipped with independent DC power supply in substation
It carries and electric power safeguard is provided.The effect of DC power supply is: providing combined floodgate DC power supply when normal for the breaker in substation；
It is that relay protection and automatic device, breaker closing and tripping, carrier wave lead in the case that electricity interrupts in substation when failure
Letter.Therefore the DC power supply of substation is that substation equipment network provides the last line of defense of power supply guarantee, is stablized
To preventing system destruction, fault spread and equipment badly damaged most important, it normal whether, is directly related to electric power for operation
The safe operation of system.
Existing transforming plant DC power supply, is mostly constituted by fixing the battery pack connected in series and parallel, but since installation is put into
After use, with regard to lacking the related operation and maintenance of progress and effectively managing, often due to being repaired not in time in use,
It often charges not in time so as to cause single battery in battery pack, capacity decline, to influence entire DC power supply
Capacity and service life, more seriously resulting in entire backup power system can not play a role and entire power supply system
Collapse, therefore to battery pack formed DC power supply effectively managed, monitored on-line and guaranteed its stable operation show
It obtains especially important.
Currently, hidden danger present in the existing battery DC power supply operation of substation mainly has:
(1) battery life as caused by Slurry pump substantially reduces
The battery pack that existing fixation connects in series and parallel is after installation is come into operation, with regard to the related operation and maintenance of shortage progress and effectively
Ground control, often due to being repaired not in time in use, causes certain single batteries to deteriorate too early, and do not have
Have and the single battery to go wrong is safeguarded in time, occurs identical problem so as to cause entire battery pack, with the time
Increase and problem worsening, will lead to entire DC power supply premature failure, more seriously affect back power supply system
The stability of the effect of system and entire power supply system.
(2) substation batteries system O&M problem
Existing single battery is fixed to use series-parallel connection type, when a certain piece of single battery breaks down, it is necessary to every
From the maintenance and replacement that entire battery branch just can be carried out single battery, the work of transforming plant DC power-supply system is greatly reduced
How efficiency and reliability it is particularly important form a set of O&M control strategy for not influencing DC power system normal work.
(3) transforming plant DC power supply lacks effective use
Transforming plant DC power supply most times are in " awaiting orders " state, to a certain extent for waste battery resource,
If effectively regulated and controled, DC power supply can participate in the peak load shifting of power grid in substation, increase entire power grid
Stability and dependability, vitalize the DC power supply storage in a large amount of substations, while transforming plant DC can also be increased
The storage of power supply improves the redundancy and stability of transforming plant DC power supply.
In addition to this, the O&M of transforming plant DC power supply and control face always O&M burden weight, low efficiency, cost
The outstanding problems such as high and random catastrophic failure, existing traditional battery topological structure and battery control technology have been unable to meet change
The needs of power plant safety stable operation, therefore, efficient intelligentized energy content of battery managing and control system safeguards substation operation
Or even it is all particularly important for the stability of electric system.
