| 20110094212 | COMPRESSED AIR ENERGY STORAGE SYSTEM WITH REVERSIBLE COMPRESSOR-EXPANDER UNIT - A system and method for compressing and expanding air in a compressed air energy storage (CAES) system is disclosed. A CAES system is provided that is alternately operable in a compression mode and an expansion mode and includes therein a motor-generator unit and a drive shaft connected to the motor-generator unit that is configured to transmit rotational power to and from the motor-generator unit. The CAES system also includes at least one reversible compressor-expander unit coupled to the drive shaft and configured to selectively compress and expand air, and an air storage unit connected to the reversible compressor-expander unit and configured to store compressed air received therefrom, with the at least one reversible compressor-expander unit compressing air during the compression mode and expanding air during the expansion mode. | 04-28-2011 |

| 20100011875 | SYSTEM AND METHOD TO MINIMIZE IMPACT OF SLUG EVENTS - A system for stabilizing flow in a pipeline is provided. The system includes at least one of an internal supply or an external supply configured to provide fluid into the pipeline such that a ratio of liquid to gas in the flow is within an acceptable range. The system also includes one or more sensors configured to indicate the ratio of liquid to gas in the fluid. The system further includes at least one valve configured to regulate a flow of the fluid from the internal supply or the external supply into the pipeline based upon the ratio indicated by the one or more sensors. | 01-21-2010 |
| 20100011876 | CONTROL SYSTEM AND METHOD TO DETECT AND MINIMIZE IMPACT OF SLUG EVENTS - A system for detecting and controlling a slug event in a flow through a pipeline is provided. The system includes multiple sensors configured to indicate one or more parameters of the flow for a slug at multiple locations in the pipeline. The system also includes a controller configured to receive one or more response signals corresponding to at least one of the parameters from the sensors. The system further includes a variable speed drive system electrically coupled to the controller and a compressor pumping fluid in the pipeline such that a ratio of liquid to gas is within an acceptable range, wherein the variable speed drive is configured to receive one or more signals from the controller and further configured to regulate at least one of a translational or a rotational speed or a power of the compressor based upon the signals. The system also includes a display unit coupled to the controller, the display unit configured to output the plurality of signals received from the controller. | 01-21-2010 |

| 20090099702 | SYSTEM AND METHOD FOR OPTIMIZING WAKE INTERACTION BETWEEN WIND TURBINES - A system and method to increase the overall power output of a windpark during conditions when the wake created by an upstream turbine effects the power production of a downstream turbine. Minimizing the wake effects created by an upstream turbine on a downstream turbine increases the net power produced by both the upstream and downstream turbines. The invention is an implementation of an algorithm to determine the controller settings of one or more upstream turbines to increase total energy capture of the turbines in the windpark. The algorithm also reduces the fatigue loads on the downstream turbines by reducing the turbulence created by the wake effects of the upstream turbine. | 04-16-2009 |
