Electric Motor Driven Compressors: Basic Principles & Operation
Electric motors are now considered a valid alternative to reciprocating engines for gas transportation service. In areas where environmental permits are hard to get and electricity is readily available and reasonably prices, operators are installing electric motors as the prime movers for their gas compressors. Electric motors are being used to drive both reciprocating and centrifugal compressors. Electric motors are a relatively new and unusual for traditional operators and field personnel who grew up with reciprocating engines. This short course will provide an introduction to the basic principles and operation of electric motor driven compressors. Discussion topics will include basic construction and principles of electric motors, principles of synchronizing the motor with the electric grid, electric substation basics, fixed speed versus variable speed motor operation, reciprocating compressor configuration and basic operation, and centrifugal compressor configuration and basic operation.
