Embodiment Construction
[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0033] In order to improve the reliability of the UPS system operation and reduce the large amount of energy waste in the operation of the UPS system at a low load rate, and to keep the UPS system running at a reasonable load rate, the present invention ensures that the UPS system is automatically based on the current total load Under the redundant power supply capability that the UPS system should have, determine the number of UPS units put into operation, automatically wake up (ie turn on) or turn off (ie sleep) one, or even multiple UPS units, so that the UPS system runs at a reasonable load...

The invention provides an uninterrupted power supply intelligent parallel operation power supply control system and method which are used for achieving power supply control over a UPS system. The power supply control system comprises a load detecting unit, an awakening control unit and a turning-off control unit, wherein the load detecting unit is used for detecting the current load attribute of the UPS system, the awakening control unit is used for awakening at least one of UPS units in the dormant state currently to be in the power supply state when the current load attribute meets the first preset condition, and the turning-off control unit is used for turning-off at least one of the UPS units in the power supply state currently to be in the dormant state when the current load attribute meets the second preset condition. The UPS units are awakened or turned off according to the load attributes of the UPS system, the operation security of the UPS system can be improved, meanwhile, the operation cost of a machine room can be greatly lowered, and energy is saved.
Description
Technical field [0001] The present invention relates to the field of uninterruptible power supply, and more specifically, to an uninterruptible power supply intelligent parallel power supply control system and method. Background technique [0002] Today's society has entered the information age. With the prosperity of the Internet, the importance of data in the era of big data is self-evident. In order to meet the data needs of the big data era, various data centers have sprung up like bamboo shoots after a rain, such as network data centers, enterprise data centers, backup data centers, etc., communication operators, banking and financial systems, governments, and large enterprises, etc. The construction of large-scale data center computer rooms is underway. How to ensure the safe operation of the data center computer room is the primary proposition for the design of the computer room power supply system. [0003] The power load of the data center power supply equipment is usual...
