Abstract
The invention provides a parallel working UPS system which is enabled to take both cost and battery backup capability into account. The parallel working UPS system is divided into a plurality of subsystems, wherein in at least one subsystem, one backup battery pack is shared by a plurality of UPS power modules. The invention also provides a method for controlling the synchronous action of the chargers of the UPS power modules in the UPS system; if any one UPS power module is switched to be powered by the backup battery pack in one subsystem, the chargers of all the UPS power modules in the subsystem are closed. The invention also provides a method for controlling the quit of the UPS power modules; specifically, if low voltage warning appears on one backup battery pack, whether other UPS power modules in the system are enough to bear the load after the UPS power module powered by the backup battery pack at the moment quits the system is determined, and if so, the UPS power module is controlled to quit the system, and the other UPS power modules in the system are controlled to bear the load. The method is mainly implemented by use of a computer program.
Description
Technical field
The invention relates to the ups system of parallel operation, and the control method of charger synchronization action to UPS power module whole in one of them subsystem, with to UPS power module withdrawal control method wherein, the all or part of step of the method by setting up functional module construction, can have been come by computer program instructions computer for controlling system.These computer program instructions store in a computer-readable storage medium.
Background technology
At present, working at multiple UPS power wired in parallel (can be multiple stage UPS parallel operation, the i.e. power module parallel work of multiple stage UPS, also can be the multiple UPS power wired in parallel work in a UPS) system in, only has a backup battery group, in system, all UPS power module shares this battery pack, then during city's electrical anomaly, each UPS power module is all from this backup battery group power taking, if but backup battery group breaks down, then system is without battery backup ability, each UPS power module configures separately a backup battery group, along with the increase of UPS power module number, backup battery group quantity also will increase, backup battery group manufacturing cost, take up room, the cost of each side such as plant maintenance also will increase greatly.
Summary of the invention
The object of the invention allows the ups system of parallel operation take into account cost and battery backup ability.
The invention provides the ups system of first parallel operation, comprise multiple UPS power module of parallel operation and multiple backup battery group, it is characterized in that, native system is divided into multiple subsystem, all be assigned described UPS power module and described backup battery group in each subsystem, wherein have at least one subsystem and have multiple described UPS power module to share backup battery group described in one.
The invention provides the ups system of second parallel operation, and it is on the basis of the ups system of first parallel operation, and UPS power module has charger.
The invention provides the ups system of the 3rd parallel operation, it is on the basis of the ups system of second parallel operation, the charger synchronization action of whole UPS power module in a subsystem, synchronization action comprises charging, and to close synchronization action as follows: in subsystem, any one UPS power module turns the backup battery group charger triggering all UPS power modules in this subsystem of powering and all closes, in order to avoid the backup battery group of powering is caused damaging by charging.
The ups system of the invention parallel operation on the one hand, multiple UPS power module shares a backup battery group to save cost, on the other hand, even if an intrasystem backup battery group of son breaks down, also the backup battery group can allocating other subsystem is come personal or shares with other subsystem, improves the back-up capability of system.Compared with prior art, the invention can realize the flexible configuration between UPS power module and backup battery group, has taken into account cost and battery backup ability.
The invention gives following method, and all or part of step wherein by setting up functional module construction, can have been come by computer program instructions computer for controlling system.These computer program instructions store in a computer-readable storage medium.
To the control method of the charger synchronization action of the UPS power module in the ups system of second parallel operation that the invention provides, if subsystem any one UPS power module interior turns backup battery group and powers, then close the charger of all UPS power modules in this subsystem.
To the control method that the UPS power module in the ups system of first parallel operation that the invention provides exits, particularly, there is low pressure warning in a backup battery group, just judge that the UPS power module of being powered by this backup battery group exits native system, in native system, whether other UPS power module is enough to bear load, if then control this UPS power module to exit native system, and control other UPS power module in native system and bear load.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the ups system of parallel operation.
Embodiment
The ups system of parallel operation is as Fig. 1, comprise n UPS power module and m the backup battery group of parallel operation, UPS power module has charger, and the configuration such as each backup battery Battery pack type, battery number, battery capacity can be all consistent, also can be different.Native system is divided into multiple subsystem, is all assigned UPS power module and backup battery group in each subsystem, and for subsystem 1, be assigned three UPS power modules and a backup battery group 1 in it, these three UPS power modules share backup battery group 1.Outside subsystem 1, configure separately a backup battery group can to one of them UPS power module, multiple UPS power block configuration also can to become to share multiple backup battery group.
The charger synchronization action of whole UPS power module in a subsystem, synchronization action comprises that the charging of charger is opened, all floatingly die-cutly to be changed, charging voltage is consistent, and also comprising charging, to close synchronization action as follows: in a subsystem, any one UPS power module turns the backup battery group charger triggering all UPS power modules in this subsystem of powering and all closes.In a subsystem, one of them UPS power module is primary module, and it controls the charger synchronization action of all UPS power modules in affiliated subsystem.In native system, one of them UPS power module is main frame, the information such as operating state, battery state, system load amount of all UPS in main frame real-time collecting system, in the arbitrary subsystem of host-controllable system, all synchronization action is closed in the charger charging of UPS power module.In order to avoid conflict, in the subsystem of main frame belonging to it, serve as primary module.
Backup battery group low pressure triggers the UPS power module of being powered by this backup battery group and is guaranteeing to exit native system under the prerequisite that load is born, particularly, there is low pressure warning in a backup battery group, main frame just judges that the UPS power module of being powered by this backup battery group exits native system, in native system, whether other UPS power module is enough to bear load, if then control this UPS power module to exit native system, in order to avoid damage the backup battery group of electric energy deficiency, and control other UPS power module in native system and bear load, then control whole system unification if not and turn bypass output, if bypass cannot be turned to be exported, just unified disconnection exports.
