Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] The invention provides a power distribution system, which can especially be used as a power distribution system in a data machine room. see image 3 , is a functional block diagram of the first embodiment of the power distribution system according to the present invention. Such as image 3 As shown, the power distribution system at least includes a mains network 10 , a generator 20 , a group of AC power consumers 30 and a storage battery 40 . Wherein the AC power equipment group 30 is powered by the mains network 10 when the mains network 10 is normal. When the mains network 10 is abnormal, such as when the mains fails or fails, the generator 20 receives a signal indicating that the mains network is abnormal, and starts to start. Before ...

Abstract

The present invention relates a distribution system. The distribution system comprises an electric supply network, a generator, a storage battery and an alternating current electric device group; the electric supply network is configured to supply power to the alternating current electric device group when the electric supply network is normal; the generator is started when the electric supply network is abnormal; the storage battery is configured to supply power to the alternating current electric device group prior to the start completion of the generator. The distribution system further comprises an AC / DC conversion module configured to convert the alternating current of the generator to direct current of the generator after the start completion of the generator so as to output and supply to the storage battery; the AC / DC conversion module and the storage module are combined to supply power to the alternating current electric device group when the total demand power of the current operation load is larger than the preset power of the generator, or else, the AC / DC conversion module is configured to supply power to the alternating current electric device group and supply power to the storage battery. The distribution system further comprises a reactive compensation module. The distribution system is able to handle the load with pulsation power requirements, so that the capacity configuration of a generator is reduced.

Description

technical field [0001] The present invention relates to power supply technology, more specifically, to a power distribution system. Background technique [0002] see figure 1 , is a functional block diagram of a first embodiment of an existing typical power distribution system, such as a power distribution system in a data center. Such as figure 1 As shown, the power distribution system is mainly composed of a mains network 10 , a generator 20 , an AC power equipment group 30 , a storage battery 40 and an ATS (automatic transfer switch) switching module 50 . Wherein the mains network 10 can be one or two lines, and the generator 10, such as a diesel generator, is used as a backup power supply after the mains power failure. When the mains network 10 is normal, the ATS switching module 50 introduces the mains power to the AC power equipment group 30 . When the mains network 10 is abnormal, such as a mains power outage or failure, the ATS switching module 50 will send a sig...
