Description

22-355 kW

The converter generator systems allow for generation of energy from hydro-generators and the transmission of this energy into the existing electrical grid within the range of 22-355 kW.

Specifications:

• Rated grid voltage: 3 x 400 VnAC, 50 Hz
• Rated power: 22-355 kW
• Power factor: cosφ = 1
• Efficiency: η > 0.95 (excluding efficiency of the generator and passive elements in the circuit)
• Current total harmonic distortion (THD): THD < 5%
• Boost voltage module: DC circuit “boost” type
• Grid-connected operation with the option of autonomous “island operation” (“off-grid”)
• Anti-Island Protection, which allows for automatic disconnection from the receiving grid in case of power cut in the public electricity grid
• Protection: against short circuits, overvoltage, undervoltage, overheating, loss of voltage or phase, and load asymmetry
• Installation method: in a control cabinet
