Description
Technical Field
The invention belongs to the technical field of emergency power supplies, and particularly relates to a UPS system based on an active maintenance function expansion device.
Background
As is well known, the UPS as an emergency power supply is widely applied to various industry departments, provides power supply guarantee for critical loads, and is extremely important in working stability and safety. And because the user has the problems of improper management, improper maintenance or improper storage battery aging, improper capacity configuration and the like of the UPS power supply system in the use process, faults such as line short circuit, storage battery breakdown and the like of the UPS power supply system are easily caused, even fire disaster is caused, and safety accidents and great losses are caused.
The national patent office published application number 201510149311.9, "remote maintenance device for uninterruptible Power supply", records in the background that "UPS working state needs to be obtained by periodically inspecting substation equipment by a station attendant". However, as the grid evolves, the number of substations increases, resulting in an extended period of manual inspection. Once the UPS storage battery fails, the UPS storage battery is difficult to find in time only by manual inspection, and the safe operation of the RTU in the transformer substation can be influenced. In addition, in the use process of the UPS, the storage battery is required to be charged and discharged at least once every year, and manpower and material resources are consumed by manually performing the charge and discharge maintenance. The technical scheme only monitors the serial end voltage of the storage battery, can not monitor the health and working condition of each storage battery, and the charge and discharge of the storage battery maintenance only adjusts the power path, can not utilize the charge and discharge control circuit of the UPS, and can not realize a reasonable charge and discharge process.
The national patent office published application number: 201510115561.0A monitoring device for charging voltage of an uninterruptible power supply storage battery is described in the background technology and the invention content of the specification, however, the condition that the charging voltage is too high or too low may exist when the current UPS charger charges the storage battery, so that the battery capacity of the UPS storage battery is reduced, the service life is shortened, and the polar plate of the storage battery is damaged. The embodiment of the invention provides a monitoring device for the charging voltage of a storage battery of an uninterruptible power supply, which is used for solving the problems that the battery capacity of the storage battery of the UPS is reduced, the service life is shortened and the polar plate of the storage battery is damaged due to the fact that the charging voltage of the storage battery is possibly too high or too low when the storage battery is charged by a current UPS charger. The technical scheme only monitors the serial end voltage of the storage battery pack, can not monitor the health and the working condition of each storage battery, and if each storage battery needs to be monitored, a monitoring device is required to be installed for each storage battery, which is obviously not feasible; in addition, even if a monitoring device is arranged on each storage battery, the monitoring effect is greatly reduced because the influence of temperature and use environment on the storage battery is ignored by only comparing the voltage value of the terminal voltage.
The national patent office also published application number: 200710100691.2 "nested redundant uninterruptible power supply devices and methods" it is described in the background and summary of the specification that "a variety of different techniques have been used to improve the reliability of uninterruptible power supply systems. These techniques include redundancy in reserve, redundancy in series, and redundancy in parallel methods. A typical backup redundant UPS architecture includes one or more UPS units operating on a backup basis, either unloaded or only partially loaded, that are capable of immediately replacing a failed UPS unit by a switchover of the load. A typical serial redundancy arrangement includes first and second UPSs connected in series, wherein in a first mode of operation the first UPS is bypassed and the second UPS is used for on-load, and in a second mode of operation the second UPS is bypassed and the first UPS is used for on-load, such that the first and second UPSs can act as backup backs of each other. In a typical parallel redundancy arrangement, a plurality of Uninterruptible Power Supplies (UPSs) are coupled in parallel to a load in order to provide redundancy and generally increased load capacity. Parallel redundancy arrangements of AC power sources (e.g., UPS) have been described, for example, in U.S. Pat. No.5,745,357 to Tassiino, jr et al, U.S. Pat. No.6,549,440 to Tassiino, jr et al, U.S. Pat. No.6,803,679 to Luo et al, U.S. Pat. No.6,118,680 to Wallace et al, U.S. Pat. No.4,104,539 to Hase, U.S. Pat. publication No.2005/0162792 to Wang et al, and U.S. Pat. publication No.2005/0073783 to Luo et al. The invention relates to a method for controlling the quantity of mutual standby among a plurality of UPS units, which comprises the steps of selectively enabling and disabling the UPS in a redundancy group according to the load size; the standby UPS unit is only standby, and neither operation nor standby is necessary to charge and discharge the battery with maintenance.
At present, lead-acid storage batteries widely used in UPS have many factors influencing the safety, and the conditions are complex, and the important factors in at least the following aspects are summarized:
1) Most of storage batteries adopted by UPS are energy storage batteries, the charge and discharge power of the storage batteries is limited by the design and materials and processes of the products, and the charge and discharge current is 0.1C when the product performance and the recommended use temperature are 25 ℃ when leaving the factory; it is also generally recommended to work continuously for < 5 minutes at 0.3C; the storage battery configured by most of the current user UPS systems is less than or equal to 2 hours, the storage battery reaches 0.5C when in full load operation, and the storage battery reaches more than or equal to 0.25C when in 50% load operation; this seriously affects the health of the battery and presents a safety hazard; particularly, when the internal resistance of the storage battery is inconsistent or partially aged, the storage battery is extremely easy to generate fire disaster when the accident is serious;
2) In general, a storage battery of a UPS is in a floating state for a long time, and a capacity of the storage battery is reduced due to crystallization of a polar plate, so that the storage battery needs to be charged and discharged with a large current within a certain time to melt chemical substances in the crystal to activate.
3) In many storage batteries, certain difference exists when leaving the factory, the difference is gradually increased in the gradual aging process, the monitoring of the storage batteries by the current UPS system is mainly based on terminal voltage, and when the terminal voltage of the storage battery string is normal, the over-charge or the under-charge of the individual storage batteries can be caused, so that the occurrence of accidents caused by the early failure of the individual storage batteries is extremely easy to cause.
4) In order to improve the reliability of the UPS system, the prior art generally adopts an n+m redundant UPS system, i.e. more than one redundant UPS unit is added to be used as a backup unit system of each other, and the backup UPS unit is replaced when the other UPS fails; but none of them lacks on-line maintenance of the battery and cannot overcome the problems associated with the use of the battery.
