Liebherr has unveiled its new Liduro Wind low-voltage frequency converter system for power outputs of up to 8 MW in back-to-back configuration. The power output of this system ranges from 1.5MW to 8MW and is designed for a voltage range of up to 690 V.
The frequency converter is suitable for geared, hybrid and direct drive wind turbines utilising full inverters with both permanent magnet synchronous generators and separately excited synchronous generators. The frequency inverter system can be installed in within a nacelle or on a tower platform. The company has equipped the new frequency converter system with a new cooling concept that keeps the temperature of the individual components low. The frequency converter cabinets are designed with IP 54 level protection and are completely closed and are applicable in extremely hot or cold regions without a change in their mechanical structure. Liduro Wind is based on a platform architecture.
