Research on Intelligent Energy-Feedback Device for Large-Capacity Storage Battery Discharge

In power system the reliability of DC operating power is largely decided by the storage battery. According to large-capacity storage battery discharge demand and requirements for energy-saving and emission-reduction, a new intelligent battery discharging device that can feedback energy was designed. In this paper, this device is introduced in details including the circuit structure, parameters design and control methods. The experimental results indicate that the device has a good discharge performance, small discharge ripples, good stability and reliability, convenient and visual monitoring, and a good engineering application value.
