Abstract
The invention provides an energy storage container system and an energy storage power station. The energy storage container system comprises a container and an energy storage system integrated in thecontainer. The container sequentially comprises an energy storage chamber, a voltage transformation chamber and an inversion chamber from one end to the other end. The energy storage system comprisesan energy storage battery pack and a confluence cabinet which are arranged in the energy storage chamber, and the confluence cabinet is used for confluence of direct-current voltage output by the energy storage battery pack; the energy storage system also comprises a PCS inverter arranged in the inversion chamber, and the direct-current voltage after confluence of the confluence cabinet is connected to the direct-current side of the PCS inverter; and the energy storage system also comprises a transformer, a wire inlet cabinet arranged in the voltage transformation chamber and a wire outlet cabinet connected with the wire inlet cabinet, the low-voltage side of the transformer is connected with the alternating-current side of the PCS inverter, the high-voltage side of the transformer is connected with the wire inlet cabinet, and the wire outlet cabinet is used for being connected with a power grid or used for being connected with a confluence container system. The energy storage container system provided by the invention is small in size, small in occupied space, convenient to transport, move and hoist, short in cable length and low in cost.
Description
technical field [0001] The present invention relates to the technical field of energy storage systems, and more specifically, to an energy storage container system and an energy storage power station. Background technique [0002] The energy storage system is a key part of solving the problems of large-scale access to renewable energy and abandoning wind and light; it is a necessary part of the development of distributed energy, smart grid, and energy Internet; An important supporting part of energy generation and transmission efficiency, safety and economy. The existing energy storage container is divided into two parts: battery energy storage container and medium voltage container: inside the battery container there are battery racks and secondary power distribution parts or inside there are battery racks and PCS inverters, and inside the medium voltage container there are PCS inverters. Transformers, transformers, high-voltage switchgear and power distribution cabinets o...
