Description

Technical Field

[0001] The utility model relates to the field of container-type energy storage cabinets, in particular to a container-type energy storage cabinet. Background Art

[0002] Oilfields are often located in remote areas without access to utility power. For oil drilling platforms, electric drilling rigs are powered by diesel or gas-fired generators. These generators are then connected to the grid through a power generation control system to form a local power grid within the well site, providing power to drilling equipment such as the winch, rotary table, and mud pumps. When drilling or encountering hard rock, the oilfield rigs experience sudden load increases on the diesel / gas-fired generators. To prevent generator shutdown and drill bit jams during these sudden load increases, sufficient power is reserved for these situations. The load factor of diesel / gas-fired generators is limited to 50%. On the one hand, long-term low-load operation of diesel / gas-fired generators increases mechanical wear on the engines, shortening their service life. On the other hand, low-load operation results in high fuel / gas consumption, resulting in high energy consumption and poor economic efficiency. To address the above issues, the use of containerized energy storage cabinets is being considered to provide independent power to oilfield drilling rigs when lifting the drill and drilling into hard objects such as rock. This will increase the load factor of the diesel / gas generator set during operation, reduce mechanical wear on the engine, increase engine life, and reduce fuel / gas consumption. The reference application number for the containerized energy storage cabinet is 202223003243.X, and the name is a Chinese utility model patent for a containerized energy storage cabinet and system. Existing containerized energy storage cabinets all use an integral installation and overall heat dissipation type. Although this is simpler and more convenient in terms of structural design, installation, and transportation, the heat dissipation efficiency of components such as the energy storage inverter and battery module is low, which has an adverse effect on the performance and service life of the components and the power increase of the unit.

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0024] The utility model provides a container-type energy storage cabinet, which uses the container-type energy storage cabinet to provide a separate power supply for the oilfield drilling rig when lifting the drill and drilling into hard objects such as rocks. When the load suddenly increases, the energy storage system provides power, and the diesel / gas generator set only provides power for the oilfield drilling rig during stable drilling. The oil / gas generator set does not need to reserve additional power reserves, and its operating load factor can be greatly improved. The engine can usually operate close to full load, reducing engine mechanical wear and also reducing fuel / gas consumption rate. The energy storage converter is an inverter that can realize bidirectional conversion and storage of energy. It can convert DC power into AC power, and can also convert AC power into DC power for storage. When the energy storage system bears a sudden load, the energy storage converter converts the DC power output by the energy storage battery into AC power.
