Description
Technical field
The invention belongs to emergency service power technique fields, and in particular to a kind of multiple subsystem of Centralized Monitoring
The N+M redundancy ups systems of composition.
Background technology
The UPS for being known as emergency service power supply is widely used in every profession and trade department, is crucial negative
Carry and provide power supply guarantee, its job stability, security are of crucial importance.And due to user in use
In the presence of the miscarriage to UPS electric power systems, safeguard that not in place or battery aging, capacity configuration are improper
The problems such as, easily cause UPS electric power systems line short, battery and the failure such as puncture, even result in fire
Occur, cause security incident and heavy losses.
State Patent Office discloses application number 201510149311.9《The remote maintenance dress of uninterrupted power source
Put》It describes in the introduction, and " [0003] UPS working conditions need to lean on plant stand person on duty's periodical inspection
Substation equipment is obtained.However as power network development, transformer station's quantity increase causes the manual patrol cycle to prolong
It is long.Once UPS batteries break down, it is difficult to find in time only manually to make an inspection tour, and this can influence transformer station
Interior RTU safe operation.And during UPS use, at least need to carry out one to battery every year
Secondary charge and discharge maintenance work, it is artificial to carry out charge and discharge maintenance work labor intensive material resources." in order to solve above-mentioned ask
Topic, it is proposed that《The remote maintenance device of uninterrupted power source》, it is electric that the technical scheme only monitors batteries string end
Pressure, it is impossible to monitor the health and working condition of each battery, and battery service discharge and recharge also only
It is regulation electrical path, it is impossible to utilize the charge-discharge control circuits of UPS in itself, it is impossible to realize rational charge and discharge
Electric process, therefore the problem of solve needed for can not effectively solving.
State Patent Office discloses application number：201510115561.0《Uninterrupted power source battery charging electricity
The supervising device of pressure》It has recorded in the background technology and the content of the invention of specification, and " [0003] is however, work as
Preceding UPS chargers there may be the too high or too low situation of charging voltage when being charged to battery, cause
The battery of UPS batteries holds Electricity Functional decline, and service life shortens, the problem of accumulator plate is damaged.[0004]
Embodiments of the invention provide a kind of supervising device of uninterrupted power source battery charging voltage, current to solve
UPS chargers the too high or too low situation of charging voltage is there may be when being charged to battery, cause UPS
The battery of battery holds Electricity Functional decline, and service life shortens, the problem of accumulator plate is damaged." its technology
Scheme only monitors batteries string terminal voltage, it is impossible to monitor the health and working condition of each battery, such as
Really each battery will monitor that and be accomplished by installing monitoring to each battery using its technical scheme
Device, this is clearly infeasible；This other scheme even installs a monitoring to each battery
Device, because its magnitude of voltage for comparing terminal voltage ignores the influence of temperature and use environment to battery,
Its monitoring effect is set to have a greatly reduced quality.
State Patent Office also disclosed application number：200710100691.2《Nested redundant uninterruptible power supply is filled
Put and method》It has recorded " [0004] a variety of different skills in the background technology and the content of the invention of specification
Art has been used for improving the reliability of uninterruptible power system.These technologies include standby redundancy, series redundancy
And parallel redundancy method.Typical standby redundancy UPS structure include operating in it is standby on the basis of, without
Load or only with fractional load, one or more UPS units, it can be by the switching of load
To replace failure UPS cell operations immediately.Typical series redundancy arrangement includes the connected in a series arrangement
One and the 2nd UPS, wherein, in the first operating mode, the first UPS is bypassed and the 2nd UPS is used for band and born
Carry, in the second operating mode, the 2nd UPS is bypassed and the first UPS is used for bringing onto load, so, first
Can be mutually as the standby backup (standby backup) of other side with the 2nd UPS.[0005] typically simultaneously
Join in redundant arrangement, multiple uninterrupted power sources (UPS) are coupled in parallel to load, to provide redundancy and to lead to
Increased load capacity is often provided.The parallel redundancy of AC power supplies (such as UPS) arranged in such as Tassitino,

State." its content of the invention is selectively to enable and disable the UPS in redundancy group according to payload, control many
Quantity standby each other between individual UPS units；Also only it is standby, operation as standby UPS units
Consider to carry out necessary maintainability charge and discharge with the standby situation for not accounting for battery, also not to battery
Electricity.
It is well known that UPS security, reliability are decided by the health status of ups system, and UPS
The health status of system depends on the health status of battery, and (in UPS standby operations, circuit breaks down
Problem, can be detected and maintenance of alarming immediately), and the situation of battery is then seldom effectively detected, its
Security makes people worried.The wide variety of lead-acid accumulators of current UPS, influence the factor of its security a lot,
Situation is also more complicated, concludes key factor at least following aspects：
1) battery that UPS is used is mostly accumulation energy type battery, its charge-discharge electric power by product design and

Flow for 0.1C；Typically also advise continuous work ＜ 5 minutes during 0.3C；Major part user's ups system is matched somebody with somebody at present
Battery≤2 hour put, reach 0.5C during oepration at full load, also >=0.25C during 50% load operation；This is tight
Ghost image rings the health of battery and there is potential safety hazard；Particularly accumulator internal resistance is inconsistent or during the aging of part,
Easily occur can occur fire when accident is serious；
2) generally UPS battery is chronically at floating charge stand-by state, and pole plate crystallization causes capacity to decline, needed
High current charge-discharge is carried out to battery within the regular hour and melt crystal active chemistry therein to reach
Material.
3) in many batteries, certain difference is there is during due to dispatching from the factory, in gradual ageing process
Difference is also gradually increased, and current ups system is exactly terminal voltage to the monitoring Main Basiss of battery,
The terminal voltage of batteries string may have resulted in indivedual accumulator super-charges or charge less when normal, easily cause individual
Other battery premature failure and the generation for causing accident.
4) battery needs periodicmaintenance, at least carry out every year a maintainability discharge and recharge twice and battery by
Individual detection, is substantially artificial progress at present, wastes time and energy, is easy to careless omission and this process needs necessarily
The design and service ability of time effects ups system.
5) in order to improve uninterruptible power system UPS reliability, prior art generally uses N+M redundancies UPS
System, that is, increase more than one redundancy UPS units, makes its standby backup unary system mutually as other side
System, the UPS units of standby backup are replaced during another UPS failures；But lack to enter battery
Row on-line maintenance, it is impossible to overcome the relevant issues during above-mentioned battery use.
