Provide module or integrated power supply, which is applied to the backup power supply of distribution network automation equipment, monitoring instruments, signal transmission and actuators, to meet the system’s requirements for long life, high reliability, maintenance-free, and wide temperature range.
Provide KW-MW supercapacitor energy storage unit for composite energy storage system of micro grid, which can provide short-term power compensation up to megawatt level for the energy storage system of micro grid, and improve the power quality of micro grid.
Due to the small scale of the micro-grid and the small inertia of the system, frequent fluctuations in the network and load are very serious, which affects the stable operation of the entire micro-grid. The supercapacitor energy storage system can effectively solve this problem. It can store the excess power of the power supply when the load is low, and feed it back to the microgrid to adjust the power demand when the load is high.
The supercapacitor energy storage system is connected in parallel to the busbar or feeder in the microgrid. During the charging and discharging process of the supercapacitor bank, the terminal voltage range changes greatly. Usually, a DC/DC converter must be used as an interface circuit to adjust the energy storage and release of the supercapacitor. able.
