Abstract: A control system for use in adapting the operation of a gas turbine is provided. The control system is configured to be coupled to at least one component of the gas turbine. The gas turbine is coupled to a power grid having a standardized frequency. The control system includes a processor and a memory coupled to the processor. The memory includes processor-executable instructions that, when executed by the processor, cause the control system to store a status of the at least one component of the gas turbine and generate and store a first operating setting for the at least one component. The first operating setting corresponds to a first frequency of the power grid that is less than the standardized frequency.

Abstract: The present disclosure relates to an APC method and tool architecture to elaborate process stability, comprising a two-loop architecture for fine tuning by an APC loop and recovery tuning by an equipment performance optimization (EPO) loop of one or more process parameters. Fine tuning by the APC loop comprises neutralization of systematic drifts from manufacturing tool or the manufacturing process itself. Recovery tuning by the EPO loop comprises aligning processing tool conditions with their tool baseline configuration. The APC method and tool architecture establishes switching criteria for fine tuning of process parameters and recovery tuning of equipment parameters. A synergy mechanism is further established between the two loops, wherein adjustments to equipment parameters made by the EPO loop are recognized by the APC loop to avoid double-tuning. The APC method and tool architecture results in manufacturing process stability within a manufacturing process module.

Abstract: A voltage control system for a wind turbine generator may include a reactive power regulator configured to control reactive power production by the wind turbine generator by adjusting a voltage setpoint for the generator. The reactive power regulator may have a first time constant and the voltage setpoint may be defined between an upper limit and a lower limit. The system may also include a voltage limit regulator configured to adjust at least one of the upper limit or the lower limit for the voltage setpoint based on a voltage-related parameter. In addition, the system may include a voltage regulator coupled to the reactive power regulator. The voltage regulator may be configured to control real power production by the wind turbine generator based on the voltage setpoint. The voltage regulator may have a second time constant, wherein the first time constant is numerically greater than the second time constant.

Abstract: A method for controlling a pilot signal (Ps) to a WPPT with an adjustable coil ratio, wherein the primary side of the transformer is connected to a plurality of WTGs and a variable reactive compensation load, the method comprising the steps of receiving an actual primary-side voltage (VMV), receiving an actual primary-side current (IQMV), estimating a line drop voltage (DV) on the basis of the compensation current (IQC) and the actual primary-side current (IQMV), forming a voltage error (Verr) as the sum of a rated voltage value (VR) and the estimated line drop voltage (DV) minus the actual primary-side voltage (VMV), namely: Verr=VR+DV VMV, and updating the pilot signal (Ps) in accordance with the voltage error (Verr).

Abstract: The present invention provides a method for operating a press which includes providing a press with at least one plunger which executed a stroke, an upper tool part, a sub-structure. A control and regulation device receives a value(s) on an operating condition from a system of the press. The value(s) are provided from the system of the press to the control and regulation device during a processing of a work piece. The value(s) provided are processed to the control and regulation device according to a function F ? ( x ) = L x · F 2 under the condition that L > x > L 2 so as to permanently operate a movement of the plunger via a drive device and the press in a controlled manner or in a regulated manner according to a system of forces required for a work piece with a respective force which is actively influenced or is actively modified in a position and a dimension/amount.
