Description
Perfect Harmony GH150 is a universal medium-voltage frequency converter of the Perfect Harmony series for high-power drives, providing maximum availability for practically any type of motor. It combines the proven multi-cell Perfect Harmony technology with flexible matching to the grid and motor sides: seamless integration of the motor and transformer, reliable operation with long cables at high voltages, and full adaptation of characteristics to the task. The converter supports different input transformer specifications, is suitable for retrofit and is optimal for high-speed motors. The output voltage is 4–11 kV in the water-cooled version and 6–13.8 kV in the air-cooled version; the power is up to 47 MVA with water cooling and up to 70 MVA with air cooling. Four cooling options are offered, including, according to the manufacturer, the largest frequency converter in the world with single-channel air cooling. Control methods are vector control of asynchronous and synchronous motors, including high-speed ones; the maximum output frequency is 250 Hz (higher on request). The best-in-class redundancy of power cells in n+1 and n+2 schemes increases reliability: if a cell fails, the drive continues to operate. The converter is gentle on the motor, the grid and the installation as a whole. GH150 is a reliable general-purpose drive that can be configured for a specific application: with marine specifications for offshore installations, as a flexible solution for pumps and compressors, or as a replacement for direct-on-line motors and gas and steam turbines. Inspire IQ condition monitoring and a full range of service offerings are supported. Industries are oil and gas, chemicals, water supply and wastewater treatment, metallurgy, marine transport and machine building. In total, the manufacturer has sold more than 30 000 medium-voltage converters with power from 100 kW to 100 MW, with built-in redundancy and global service support.
