The system means that the various interfaces in a wind farm can be replaced by a standardised, international interface. Even wind farms with turbines from other manufacturers can be controlled with a single interface. This considerably reduces project complexity and susceptibility to error. The IEC 61400-25 standard describes the multi-manufacturer standardisation of communication between the SCADA system and the wind farm components, e.g. the wind turbines or the wind farm management system. REpower Systems offers a comprehensive range of SCADA products under the name of “REguard”. The product includes hardware and software for controlling the turbines, communicating with the wind farm and visualising the operating data. The new REguard Interface B IEC 61400-25 is directly integrated into the control systems of the wind farm units. No additional hardware or software is required. REpower developed the interface in conjunction with E.ON.
