GE’s Power Conversion business has unique expertise in electrification and exhaustive knowledge of LNG processes, driving the development of high-reliability systems and strong capabilities in high-power systems. GE's extended electrical package for LNG plants includes low and medium voltage motors (up to 100 MW), generators, HV distribution, switchgear, transformers, UPS, MCC, harmonic filters, e-house, and power cables.
Starter/Helper for refrigerant compression
Increasing the power and efficiency of LNG refrigeration compressors, our converter-fed motors can be used as:
- Starter - starting the gas turbine by accelerating the shaft until the combustion enables the turbine to work alone
- Helper - providing additional power to the gas turbine if required
- Generator - regenerating the excess of power (automatic energy connections)
Full electric solution for refrigerant compression
GE can also offer a complete solution to drive the main refrigerant compressors using electrical motors (synchronous and induction), powered by high-power drives based on thyristor technology (for LCI) or on IGBT technology (for VSI). GE solutions allow complete optimization of the shaft-line, ensuring a very high level of performance for this critical application. Fully tested solutions including compressors, motors, and drives provide for an effective start-up when equipment is on site. GE can also provide electrical solutions to drive all compressors for the different services in a LNG plant.
