Abstract: Systems and methods for controlling exhaust steam temperatures from a finishing superheater are provided. In certain embodiments, the system includes a controller which includes control logic for predicting an exhaust temperature of steam from the finishing superheater using model-based predictive techniques (e.g., based on empirical data or thermodynamic calculations). Based on the predicted exhaust temperature of steam, the control logic may use feed-forward control techniques to control the operation of an inter-stage attemperation system upstream of the finishing superheater. The control logic may determine if attemperation is required based on whether the predicted exhaust temperature of steam from the finishing superheater exceeds a set point temperature as well as whether the inlet temperature of steam into the finishing superheater drops below a set point temperature of steam.

Patent number: 8909454
Abstract: A compression system includes a compressor with adjustable inlet guide vanes (IGVs) and variable stator vanes (VSVs) that are adjustable independently of each other. IGV and VSV control units produce respective IGV and VSV reference commands responsive to respective first and second inputs that may be responsive to measured properties of the compression system. The second input may be provided by a model of the compressor or of the compression system responsive to measured properties. The second input may particularly be an estimate of a property not directly observable, such as stall margin or efficiency.

Patent number: 8907510
Abstract: A method and system for reducing a disturbance of an electric grid signal in a wind turbine is provided. The method includes providing a generator for the wind turbine system, and, coupling a power converter to the generator, the power converter. The power converter is configured to monitor at least one of a negative sequence component and a positive sequence component of a signal transmitted from an electric grid, determine if a disturbance exists based on the monitored signal, determine at least a portion of a magnitude of the negative sequence component of the signal, and, orient a voltage of the signal based on the determined magnitude negative sequence component to modify the instantaneous power flow through the power converter.

Patent number: 8907716
Abstract: A device includes a controller configured to regulate one or more voltages applied to a gate of an insulated gate bipolar transistor (IGBT). The controller is configured to receive one or more voltage values associated with the IGBT, and generate a gating signal and transmit the gating signal to the IGBT. The gating signal is configured to activate or deactivate the IGBT. The controller is configured to generate a voltage clamping signal and transmit the voltage clamping signal to activate or deactivate an active switching device. The active switching device is configured to periodically limit the one or more voltage values associated with the IGBT based at least in part on one or more characteristics of the voltage clamping signal.
