Embodiment 1

[0034]Embodiment 1, with any point in the energy storage power station as the center point O, the number of battery rooms is selected to be eight, which are respectively battery rooms A to H, and the battery room H can be vacated for other purposes, and each battery room The shape is trapezoidal, and the distance D1 from the battery room to the center point is 17m, and then the eight battery rooms are evenly distributed; then seven battery clusters 1 are arranged in parallel in each battery room, and the DC output terminals 3 of the seven battery clusters 1 are Set it on the side close to the center point; then select eight sets of energy storage inverters 2, set the distance D2 from each set of energy storage inverters 2 to the center point as 13.5m, and then each set of energy storage inverters 2 Correspondingly set at the outlet of each battery room to form a figure 1 The array of regular octagonal energy storage power stations shown. Then connect the DC output terminal 3 ...

Embodiment 2

[0035] Embodiment 2, the present embodiment 2 is basically the same as the implementation 1, the only difference is that the 7 battery clusters 1 arranged in each battery room are radially arranged with the center point as the center point, so as to form figure 2 The array of regular octagonal energy storage power stations shown can achieve the same effect as the embodiment.

Embodiment 3

[0036] Embodiment 3, this embodiment 3 is basically the same as Embodiment 1, the only difference is that the eight battery rooms are fan-shaped and the 7 battery clusters 1 arranged in each battery room are radially arranged with the center point as the center point. to form as image 3 The array of circular energy storage power stations shown can achieve the same effect as the embodiment.

[0037] From the above-mentioned embodiments, the present invention is verified, thus proving that the present invention can achieve the minimum length between the battery cluster and the energy storage inverter, and there is basically no difference in length, and there will be no excessive cables in the cable trench or panel cabinet. In the middle case, the DC large-section cable is saved, and the influence of the cable impedance on the consistency of the battery cluster is reduced.

Abstract

The invention discloses a large energy storage power station and an arraying method suitable for a large energy storage power station array system. The method comprises the steps that with any point in the power station being the center point, a plurality of storage battery rooms are evenly distributed, wherein the distances between all the storage battery rooms and the center point are equal, and a plurality of storage battery clusters with the same outlet direction are arranged in each storage battery room; with the center point being the center, energy storage inverters are evenly distributed, wherein the number of the energy storage inverters is equal to that of the storage battery rooms or has a multiple relationship with the number of the storage battery rooms, and the distances between all the energy storage inverters and the center point are equal; the distance between each energy storage inverter and the center point is shorter than the distance between each energy storage inverter and the corresponding storage battery room, and all the energy storage inverters correspond to all the storage battery rooms in a one-to-one mode; each storage battery cluster is connected with the corresponding energy storage inverter, and all the energy storage inverters are connected with a power distribution device to form the energy storage power station array system. The large energy storage power station comprises the storage battery rooms, the storage battery clusters, the energy storage inverters, the power distribution device and the formed array system. According to the large energy storage power station and the arraying method suitable for the large energy storage power station array system, the cable length difference of the storage battery clusters under the same energy storage invertor can be reduced, so that cables are saved, and loss is reduced.

Description

technical field [0001] The invention relates to a large-scale energy storage power station and an arrangement method suitable for arrays of large-scale energy storage power stations, belonging to the technical field of power grid energy storage. Background technique [0002] At present, large-scale energy storage power stations usually use relatively mature lead-acid batteries and lithium batteries, while energy storage inverters require that the battery cluster cables connected to the same inverter should have the same length to ensure the consistency of the internal resistance of the battery clusters. . During the construction of large-scale energy storage power stations, battery clusters are usually distributed in containers, or are arranged in a conventional battery room. The distance between the battery clusters connected to the same energy storage inverter and the inverter varies greatly. As a result, some cables have to be coiled a lot in cable trenches or cabinets, ...
