H098-1MWH Containerized Energy Storage System Composition
Taking H098-1MWH container energy storage system as an example, the system generally consists of energy storage battery system, monitoring system, battery management unit, special fire protection system, special air conditioning, energy storage converter and isolation transformer, and finally integrated in a 40-foot container.
Battery system: mainly consists of series-parallel connection of battery cells, first of all, a dozen groups of cells through the series-parallel connection of the battery box, and then the battery box through the series connection of the battery pack series and enhance the system voltage, and ultimately, the parallel connection of the battery pack series to enhance the capacity of the system, and the integration of the installation in the battery cabinet.
Monitoring system: It mainly realizes the functions of external communication, network data monitoring and data acquisition, analysis and processing to ensure the accuracy of data monitoring, high precision of voltage and current sampling, data synchronization rate and fast execution of remote control commands. The battery management unit has high-precision single-unit voltage detection and current detection to ensure the balanced voltage of the battery cell module and avoid the generation of circulating currents among the battery modules, which affects the system operation efficiency.
Fire fighting system: In order to ensure the safety of the system, the container is equipped with a special fire fighting and air conditioning system.
Through the smoke sensor, temperature sensor, humidity sensor, emergency lights and other safety equipment to sense the fire alarm, and automatically extinguish the fire; dedicated air conditioning system according to the external ambient temperature, through the thermal management strategy to control the air-conditioning cooling and heating system, to ensure that the temperature inside the container is in the right zone, to extend the service life of the battery.
Energy storage converter: It is an energy conversion unit that converts battery DC power into three-phase AC power, and it can operate in both grid-connected and off-grid modes. In the grid-connected mode, the converter interacts with the grid in accordance with the power commands issued by the upper level dispatch; in the off-grid mode, the converter interacts with the grid in accordance with the power commands issued by the upper level dispatch.
In off-grid mode, the converter can provide voltage and frequency support for plant loads and black start power for some renewable energy sources.
The outlet of the ESC is connected to an isolation transformer, which completely insulates the primary side from the secondary side of the electricity and maximizes the safety of the container system.
