Abstract
A method and system for controlling natural gas compressor and engine units. Particularly, the control method provides for the adjustment of the engine speed and compressor loading, so as to minimize the compressing energy required while maintaining a desired gas flow through the pipeline. The control of the engine speed and compressor loading is based in part on an energy quotient value for the unit. The control method further provides for efficient operation during multiple-stage compression, by controlling the interstage pressure. The control method is also adapted to predict impending compressor and engine unit failures. The control system is based upon a digital-type controller which generates control signals in response to changes in the energy quotient value for the unit.
