Embodiment Construction
[0029] 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.
[0030] see figure 2 , is a module block diagram of the first embodiment of the flexible power distribution system according to the present invention. Such as figure 2 As shown, the flexible power distribution system includes a generator set 10, and a plurality of loads powered by the generator set 10, such as figure 2 Among them, the first load 20-1 to the m+nth load 20-m+n. Wherein, the generator set 10 may be a diesel generator set or a gasoline generator set. The present invention divides the plurality of loads into a first load group and a second load group, such as figure 2 The number of loads in the first load group is n, including the m+1th load 20-m+1, the m+2th load 20-m+2, ..., the m+nth load 20-m+n; The number of loads in the se...

The invention relates to a flexible power distribution system, which comprises a generator set, and a first load group and a second load group. The generator set provides power for the first load group and the second load group. The flexible power distribution system also comprises an AC / DC module and an energy storage module configured correspondingly to each load in the second load group. The flexible power distribution system also comprises a control module for controlling the AC / DC modules and the energy storage modules in the second load group to provide power for the load in a combined mode when the total output power of the generator set is judged to achieve the preset power to control the total output power of the generator set to be not higher than the rated power. When the total output power of the generator set is judged to be smaller than the preset power, the input power of the second load group is increased, and the AC / DC module is controlled to provide power for the corresponding load, and energy is stored in the energy storage module. The low-capacity configuration for the generator set is realized, and the utilization rate of the generator set is improved.
Description
technical field [0001] The invention relates to power supply technology, more specifically, to a flexible power distribution system. Background technique [0002] In order to ensure the reliability of the system, the traditional power distribution system, such as the power distribution system of the computer room, generally has multiple input power sources. Generators such as diesel generators are generally necessary choices, but diesel generators are large in size and high in investment. When configuring the diesel generator, in addition to considering the power factor of the diesel generator and the load, it is also necessary to consider that all loads are the maximum possible load in the working state, and most of the time the loads are not working at the maximum power state. On the whole, the configuration of diesel generators is much larger than the demand for output average power, resulting in a waste of space and funds. [0003] Such as figure 1 Shown is the connec...
