Description
GL150 is a medium-voltage frequency converter with a thyristor inverter commutated by the load (load commutated inverter, LCI), for drives of high-power synchronous motors and for starting devices. The manufacturer relies on 55 years of experience in this technology. GL150 is chosen when high starting torque and high efficiency in long-term operation are required, in power generation, the oil and gas industry, on fleets and in metallurgy. Thyristor technology provides high power density, and the proven LCI topology ensures stable operation. The output voltage is 1.4–8.3 kV in the air-cooled version and 3–12 kV in the water-cooled version; the power is 1.5–30 MVA with air cooling and 6–85 MVA with water cooling. The maximum output frequency is 125 Hz, and the control is vector control with or without a speed sensor. The degree of protection is IP20 for air cooling and IP41 for water cooling, with higher ratings on request. The air-cooled version copes easily with heavy starts, the patented compact DC-link choke saves space, and built-in four-quadrant operation makes it possible to recover energy without additional costs. An upgrade with improved low-voltage ride-through (LVRT) capability and control from third-party systems is possible. The converter stands out for high reliability, efficiency, a small carbon footprint and economy; its compact design simplifies integration, installation and operation and reduces training costs. GL150 is a proven solution from small to maximum power: for starting large gas turbines (static starting converter), for main propulsion plants of cruise liners, for driving giant compressors in the oil and gas industry, and for energy transition tasks, such as starting converters for river heat pumps and compressed air energy storage systems (CAES).
