20 MW Compressor LCI Drive: Modeling, Simulation and Measurements.
The LCI (Load commutated Inverter) is still today a suitable solution for supplying high power variable speed drive systems. The following main topics are described in this contribution: The modeling of a 20 MW LCI synchronous drive system for a compression train. The numerical simulation of the complete drive system. An original real time measurement of the air gap torque. A comparison between simulation results and measurement performed on the test shop of the manufacturer.
