MVE CONTROL: generator speed control + a regenerative inverter feeding 100 % active power directly into the grid. We design, manufacture and integrate everything under one roof in Brezno.
Water is the most stable renewable source - it flows at night, under clouds and in still air. Compared to wind and solar it has incomparable advantages:
MVE CONTROL is a tandem of two inverters. The first handles generator speed control on a water-wheel motor or turbine, extracting the maximum power from the current flow and water speed. The second - an actively controlled regenerative inverter - delivers that power straight to the grid with a power factor of 1.
On startup the system auto-synchronises to both the grid and the generator. When current, frequency or grid parameters cross safety limits, the plant is immediately disconnected by opening the input contactor.
Vertical and horizontal wheel motors placed directly in the river bed. MVE CONTROL adapts orbital speed to the instantaneous water speed.
Turbines on drinking-water gravity loops. MVE CONTROL extracts maximum energy even at minimum flow - from "zero" up to rated power.
Existing plants that fall below super-synchronous speed at low flow and would otherwise have to shut down. MVE CONTROL operates down to virtually 0 Hz generator frequency.

Extract the maximum from the variable flow of the Bebrava and run the plant reliably without permanent staff - even at low flow.
