Abstract
A system and method of controlling a compressor rack having a plurality of variable capacity components is provided. A variable capacity component is selected from the plurality of variable capacity components as a designated variable capacity component. The designated variable capacity component is operated by varying a capacity of the designated variable capacity component. Each variable capacity component of the plurality of variable capacity components, except for the designated variable capacity component, is operated at a fixed capacity corresponding to one of a maximum and a minimum capacity of the variable capacity component.
Claims18
A method of controlling a compressor rack having a plurality of variable capacity components comprising:
- selecting a variable capacity component from said plurality of variable capacity components as a designated variable capacity component, a capacity of each variable capacity component being continuously variable within an associated variable capacity range;
- operating said designated variable capacity component by varying said capacity of said designated variable capacity component;
- operating each variable capacity component of said plurality of variable capacity components, except for said designated variable capacity component, at a fixed capacity corresponding to one of a maximum and a minimum capacity of said each variable capacity component.
A system comprising:
- a controller for a compressor rack having a plurality of variable capacity components;
- a computer readable medium accessible to said controller and storing a neural network having a plurality of neurons, each neuron being associated with a corresponding variable capacity component and having a neuron output based at least in part on a predetermined preference for operating said corresponding variable capacity component;
- said controller being configured to reference said neural network and evaluate said neuron output for each neuron of said neural network, to select a variable capacity component as a designated variable capacity component based on said evaluating, to operate said designated variable capacity component by varying a capacity of said designated variable capacity component, and to operate each variable capacity component of said plurality of variable capacity components, except for said designated variable capacity component, at a fixed capacity corresponding to one of a maximum and a minimum capacity of said each variable capacity component.
