GSE CONTROL
GSE CONTROL inverters have been replaced with GSE COMP class of inverters.
GSE CONTROL 400 is a transformerless inverter designed for direct connection of an inverter or arbitrary number of parallel ranged inverters on the primary side of the grid transformer with ratio 0,4/XX kV.
GSE CONTROL 400 serves as a battery-fed bidirectional inverter for 400V three-phase power system. VONSCH GSE CONTROL 400 is the ideal product to provide the following:
- Peak-shaving
with a proper control, GSE CONTROL can be used to reduce maximum power peaks - Reactive power compensation
thanks to the measurement of currents and load voltages, the total reactive power of the system can be continuously and quickly controlled - Frequency control
Frequency control is only relevant in small island networks called "microgrid", where surplus or lack of power is reflected in an increase or decrease of the grid frequency (droop control) - Charging / discharging and forming the battery
Thanks to the fast control of the DC current (battery current), the inverters can be used to charge and recharge batteries with very high efficiency
Main advantages
- Prevention of loss of profit and additional excessive costs during power failures.
- Removes the need to shut down the company during power failure
- Increases the reliability of the electric system and the reliability of grid connected devices
Features:
- High efficiency
- Fast start-up
- Fast reaction time to step change of load
- Long durability of device
- Ecological device – minimal consumption in standby
