  • Patent number: 9732635
    Abstract: A method for enhanced cold (or warm) steam turbine start in a supplementary fired multi-gas turbine combined cycle plant is disclosed. Boiler supplementary firing, which is normally used to increase steam flow when the plant gas turbine is at maximum load, is used to augment steam production with a partly loaded, temperature matched gas turbine. This is done to satisfy minimum required steam flow for a cold (or warm) steam turbine start. Lighting the supplementary firing burners in the heat recovery steam generator/boiler and setting them at a minimum or low heat load serves to add enough steam, at the proper temperature, to insure a successful cold or warm steam turbine start when the gas turbine load and related steam production capacity from the gas turbine exhaust flow are limited by the need to match the required steam temperature and/or maintain low gas turbine exhaust emissions.

    Abstract: Exemplified herein is a graphical user interface for an industrial automation system that provides, in a single aggregated and eloquent view, a configuration workspace to discover and present configuration details of control components within an industrial automation system. These components may include industrial controllers, programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, programmable automation controllers (PACs), and the like, which have modules (as well as submodules) connected thereto. Among other things, the configuration workspace enables a holistic view of identified hardware configuration and the modular reconciliation and troubleshoot of the network device and module configurations.

  • Patent number: 9726148
    Abstract: The present subject matter is directed to a system and method for improving speed control of a pitch drive system of a wind turbine. In one embodiment, the pitch drive system includes a direct current (DC) motor having an armature and a series-field winding, a battery assembly having a positive terminal and a negative terminal, and a current-controlling device configured in series between the positive terminal of the battery assembly and the series-field winding. The battery assembly is configured to supply power to the pitch drive system and the current-controlling device is configured to supply current to the series-field winding so as to ensure a field flux does not equal zero. Thus, the current-controlling device has the effect of limiting the maximum speed of the DC motor.

  • Patent number: 9726082
    Abstract: A turbine bypass system comprises a bypass path which is selectively operable to deliver hot gases to a gas cooler and a pebble bed positioned in the bypass path upstream of the gas cooler. The pebble bed absorbs heat from the bypass gases and thereby reduces the temperature of the bypass gases prior to delivery of the bypass gases to the gas cooler.

  • Patent number: 9726108
    Abstract: A safety and input/output (I/O) module of an engine controller for an engine set of a marine vessel can be physically distinct from an engine control unit (ECU). The safety and I/O module can include hardware in addition to software, firmware, or a combination thereof. The safety and I/O module can be a single logic controller having safety functionality and I/O functionality. The safety functionality can be for dynamic engine protection during operation of the engine set of the marine vessel. The I/O functionality can be for sending signals to components external to the engine controller and for receiving signals from components external to the engine controller.

  • Patent number: 9726113
    Abstract: A turbine engine assembly is provided. The turbine engine assembly includes a core gas turbine engine including a first rotatable drive shaft, a first low-pressure turbine section in serial flow communication with the gas turbine engine, a gear assembly coupled to the first low-pressure turbine section through a second rotatable drive shaft, and a second low-pressure turbine section in serial flow communication with the core gas turbine engine. The first low-pressure turbine section is configured to rotate in a first rotational direction, and the second low-pressure turbine section is configured to rotate in a second rotational direction opposite the first rotational direction. The first and second low-pressure turbine sections are spaced axially apart from each other. The turbine engine assembly also includes a fan assembly coupled to the first low-pressure turbine section through the gear assembly, and coupled to the second low-pressure turbine section through a third rotatable drive shaft.

  • Patent number: 9726145
    Abstract: A pitch control system for a wind turbine includes a backup battery bank assigned to each pitch drive motor, with each battery bank having a plurality of individual batteries connected in series. A battery charger is connected in parallel across each battery in the battery bank. A protective circuit is configured with each battery charger and includes a voltage comparator circuit that detects a reverse voltage applied to the battery charger above a threshold value to isolate the battery charger from the reverse voltage.

  • Patent number: 9726147
    Abstract: A method for stopping the operation of a wind turbine is disclosed. The method may generally include receiving signals associated with at least one operating condition of the wind turbine, analyzing the at least one operating condition with a controller of the wind turbine, implementing a first stopping procedure in order to stop operation of the wind turbine when analysis of the at least one operating condition indicates that a pitch system failure has occurred and implementing a second stopping procedure in order to stop operation of the wind turbine when analysis of the at least one operating condition indicates that a different wind turbine stop event has occurred.

  • Patent number: 9726712
    Abstract: An assembly including an insulated gate bipolar transistor (IGBT) is provided. The IGBT is coupled with a gate driver for receiving a gating signal to drive the IGBT and providing a feedback signal of the IGBT which indicates a change of a collector-emitter voltage of the IGBT. The assembly further includes a failure mode detection unit for determining whether the IGBT is faulted based on a timing sequence of the gating signal and feedback signal. The failure mode detection unit is capable of differentiating fault types including a gate driver fault, a failed turn-on fault, a short-circuit fault, a turn-on over-voltage fault and a turn-off over-voltage fault. Accordingly, an IGBT failure mode detection method is also provided.
