Description
Technical field
The application relates to the battery technology field, particularly relates to a kind of accumulator capacity evaluation method and system.
Background technology
Explanation of nouns:
Storage battery is led: it is exactly the ability of passing on electric current that electricity is led, and has reflected that battery unit can carry out the physical features of the polar plate area of chemical reaction.
The property checked discharge: in normal operating battery pack, in order to check its actual capacity, battery pack is broken away from operation, carry out constant-current discharge with the discharge current of stipulating, as long as one of them cell batteries has been put into the final voltage of regulation, should stop discharge.
Final voltage: during accumulator capacity was selected to calculate, final voltage referred to the power load of straight-flow system, was specifying the minimum sparking voltage that requires accumulator to keep in discharge time.To accumulator itself, final voltage refers to that accumulator reaches the minimum sparking voltage that allows under the different discharge rate discharging conditions within different discharge times.Generally speaking, the former requirement is higher than the latter.
Accumulator is the important component part of DC power-supply system in the electric supply system; it is as dc power supply; mainly undertaking as electrical secondary system load in the electric system provides safety, stable, reliable electric power safeguard, guaranteeing the normal operation of relay protection, communication facilities.Therefore, the stability of accumulator and the actual capacity that can offer load in discharge process are of great significance the safe operation tool of guaranteeing power equipment.
Yet accumulator is through after the use of certain hour, the Chang Yiyin active substance comes off, grid corrosion or the factors such as pole plate distortion, sulfuration, and capacity is reduced gradually until lost efficacy, and the battery system for tens joints even tens joint series connection, in case wherein a certain joint accumulator damages too early, such as untimely discovery, then time one length can cause other accumulator to occur damaging.So, need in time find out in the electric system and lose efficacy or the undesirable accumulator of capacity, and it is processed, in order to remove a hidden danger.
Because the maintaining method of lead-acid accumulator is loaded down with trivial details, had at present exempt to add water, flexible for installation, floor area is little and the valve controlled sealed lead-acid accumulator that do not form the characteristics such as acid mist replaces.
At present, in electric system, when definite valve controlling type accumulator capacity, must carry out 100% checking discharging test to valve controlling type accumulator, it is longer obviously accumulator to be carried out for 100% property checked discharge working time, needs 10 hours approximately.And in electric system, this can realize for 220KV, 500KV electric substation, because all two group storage battery groups of this class power transformation, a group storage battery group can keep work, and other one group can be used for doing experiment, and be difficult to realize for 110KV electric substation, because this class electric substation only has a group storage battery group, so for 110KV electric substation, can only carry out 50% checking discharging test to accumulator, and can't the overall condition of accumulator be tested, can't understand the total volume of accumulator.
In addition, it is as follows that traditional storage battery checking discharges and recharges the required time estimation of work: 110KV electric substation (having a group storage battery) discharges and recharges the working time needs 13 hours at least, is specially: discharge needs 5 hours, and charging needs 8 hours; 220KV, the every group storage battery of 500KV electric substation (having two group storage battery groups) discharge and recharge the working time needs 24 hours at least, concrete: for discharge needs 9 hours at least, charging needs 15 hours.Two group storage batteries just need 48 hours at least.This still does the needed time of once circulating.This has expended staff's plenty of time.For the 110KV electric substation that only has a group storage battery group, can't understand the total volume (because of the accumulator capacity that can only put 50%) of accumulator.
By the research to prior art, the inventor finds, now traditional storage battery checking discharges and recharges work, exists following shortcoming: (1) longevity of service; (2) can not judge fast the capacity of accumulator, in emergency condition, be even more important; (3) in examination, can not judge the situation of accumulator in real time; (4) trouble accumulator the significant trouble such as is opened a way when judging, cause easily trouble accumulator blast, catch fire, bring hidden trouble for the safe operation of electric substation, and jeopardize personal safety; Reach cut-off voltage (for example 1.8V) if any a joint battery tension in (5) one group storage batteries, then the work of discharging can not continue, thereby impact is organized the judgement of the capacity of other accumulator to this.
