Description
【Technical field】
The invention belongs to storage batteries of transformer substation on-line monitoring area of maintenance, it is related to one kind and dimension is exempted from based on cell distribution
Protect intelligent DC power-supply system and its control method.
【Background technology】
In power industry, to ensure power system security and normal operation, a large amount of relay protection systems are mounted with, various
Automated system, communication system and various information management systems etc., and the reliability of these systems is carried with the development of power network
Higher requirement is gone out.To ensure uninterruptible power system (straight-flow system or exchange system that these systems can normally play a role
System) also it is increasingly becoming the focus of people's concern and research.And the energy core for constituting DC power system is battery.Normal fortune
In the case of row, battery is intended only as floating charge stand-by state and charger parallel running, and when exchanging dead electricity, battery is rapidly not
The electrical equipment for straight-flow system of interruption provides reliable direct current, is protection device in transformer station, automation equipment, thing
Therefore the equipment such as illumination provides power.Thus it is guaranteed that the performance of battery is stable most important to stablizing for transformer station direct current system,
It is to ensure the power source that the heart of transformer station is normally run.But battery after use after a while, it may appear that capacity
Decrease up to and failure phenomenon occur.
Current transformer station judges dead battery to the performance monitoring of battery by manual record, regular visit.Safeguard
Be manually periodic detection verification capacity, carry out charge and discharge maintenance, it is necessary to have a power failure, it is necessary to which battery is cumbersome connects to every section every time
Line, detection, record.Rewiring again is removed after detection and detects another section battery.Such detection program causes workload big,
The manpower minimum of one teams and groups that put into every time, the accumulator checking verification of a transformer station need to waste the two or three days.Therefore
Invention is a kind of to fall entirely ineffective battery, online to falling to battery progress status monitoring, the verification of online capacity, online bridging online
The need for the non-maintaining intelligent DC power-supply system of cell activation is intelligent substation afterwards.
There are problems and deficiency in the operation and maintenance of the batteries in traditional DC power system：
(1) parameter differences are further increased between batteries longtime running can make every section battery；
(2) it can only be charged by charging cabinet is unified to whole battery pack；Due to the capacity between battery, the presence of internal resistance difference,
Whole group is easy to charge to cause each monomer voltage unbalanced, in the case of long-term floating charge, and the long-term charge less of some batteries slowly vulcanizes, and has
A little batteries are overcharged and dehydration for a long time.
(3) new used batteries can not be shared, and battery parameter wants whole group to change battery when serious inconsistent, and this is not only wasted greatly,
Environmental issue can also be caused；
(4) single battery failure can cause whole group battery failure；
(5) cruising inspection system need to separately be matched somebody with somebody to improve system reliability；
(6) maintainability activation discharge etc. need to periodically be carried out.Periodically labor intensive, material resources and time are safeguarded in activation.It is domestic because
Safeguard that not in time occurring power-fail causes the case of major accident all to occur every year.

Electric voltage equalization is held, every batteries is all in optimum activity state all the time, realizes equalized maintenance, be that the inner walkway of next step is carried
For uniformity platform；
2) online internal resistance measurement technical testing internal resistance of single cell is used：It is accurate to judge behindhand battery；
3) line pulse activating technology is used：It is automatic under floating charge state to provide positive and negative width to the single battery that performance falls behind
Frequency pulse current is activated online, activates crystallization and the sulfuric acid precipitation of internal storage battery battery lead plate, prevents battery because long-term
Sulfation caused by floating charge；
4) technology is held using behindhand battery discharge and recharge core：The online constant-current discharge, three stages of being carried out to behindhand battery charges；
5) technology is bridged using online battery：Online bypass is carried out to dead battery using unidirectional diode to exit；
6) electric alarm technology is altered using straight-flow system exchange：Comprehensive monitoring is carried out to straight-flow system.
Compared with prior art, the invention has the advantages that：
The above mentioned problem that the present invention exists for Traditional DC power-supply system conducts a research, and is digesting and assimilating existing electric power storage
In pond equalizaing charge technical foundation, using newest Power Electronic Technique and embedded technology, develop distributed intelligence charging, put
Electricity, monitoring integrated module.Judge behindhand battery, dead battery is bridged out online, is held in line core.With expansible distributed mould
Block, unified backstage substitutes Traditional DC screen+battery inspection+artificial periodic maintenance pattern.Change traditional regular to battery
Check capacity, electric discharge charge maintenance pattern there is provided it is a kind of to cell distributed on line monitoring, it is online equalized maintenance, online
Activate, hold, online across the technology realization side for falling dead battery, the intelligent DC power-supply system of Monitoring Data remote transmission in line core
Method.
The problem of present invention can solve the problem that single battery failure effect straight-flow system normal power supply in batteries.By dividing
Cloth monitors the internal resistance of cell, finds behindhand battery, carries out online activation and safeguards, and can bridge replacing failure electricity online
Pond, straight-flow system normal power supply is not influenceed.So as to prevent the battery open circuit phenomenon of Traditional DC thrashing battery, safety is excluded
Hidden danger.Reach that new used batteries can be used with, realize that battery is safeguarded and matched automatically, behindhand battery can bridge replacing, nothing online
It must have a power failure.Battery availability is improved, beneficial to environmental protection.The establishment of distributed on-line monitoring maintenance system, can improve dc source system
The stability of system, reliability, maintainability, are allowed to the need for meeting power network development and produce economic and social benefit.
