Low pressure energy storage converter
• Rapid island detection technology
• High and low voltage crossing function
• Single machine with peak clipping and valley filling function
• Reactive power compensation and harmonic compensation functions
• Constant power, constant current charging and discharging function
• Support multi-machine parallel connection, can be expanded to MW level
Generation-side energy storage: load regulation, smoothing intermittent energy, increasing consumption of new energy, increasing reserve capacity of power grid, participating in peak regulation and frequency modulation.
Transmission and distribution energy storage: improve power quality, reduce line loss, improve the reserve capacity of the grid, improve the utilization efficiency of transmission and distribution equipment, and delay the demand for capacity increase.
User-side energy storage: smooth load curve, load transfer, peak clipping and valley filling.
Emergency power supply system: it is in standby state when the power grid is normal, and it can be started when the power grid is faulty to guarantee the continuous power supply of the load.
Fire power supply, emergency lighting, energy feedback, etc.
