Abstract: An electrical power system connectable to a power grid includes a cluster of electrical power subsystems, each of the electrical power subsystems including a power converter electrically coupled to a generator having a generator rotor and a generator stator. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid. Each of the electrical power subsystems further includes a transformer. The system further includes a subsystem breaker configured with each of the electrical power subsystems, and a cluster power path extending from each subsystem breaker for connecting the cluster of electrical power subsystems to the power grid. The system further includes a reactive power compensation inverter electrically coupled within the electrical power system, the reactive power compensation inverter operable to increase the reactive power level in the electrical current flowing to the power grid.

Abstract: A method for monitoring and controlling IGBT temperature in a power converter of an electrical power system includes generating a plurality of temperature signals from a plurality of switching devices via a plurality of temperature sensors. The method also includes selecting a primary switching device from the plurality of switching devices to estimate a primary temperature thereof. Further, the method includes determining the primary temperature of the primary switching device via a temperature measurement circuit communicatively coupled to the primary switching device. Moreover, the method includes comparing remaining temperature signals (or a function thereof) to the primary temperature via at least one comparator circuit. If one of the remaining temperature signals (or the function thereof) exceeds the primary temperature, the method also includes implementing a control action to address the increased temperature.

Abstract: A method for operating a power generation system that supplies real and reactive power to a grid includes receiving a reactive power demand made on the power generation system at an operating state of the power generation system and a grid state. Further, the method includes decoupling reactive power control and voltage control between a generator and a reactive power compensation device so as to reduce an oscillatory response of a reactive power output from the reactive power compensation device and the generator. Moreover, the method includes operating, via a device controller, the reactive power compensation device in a reactive power control mode to generate at least a portion of the reactive power demand.

Abstract: A control method for dynamically controlling active and reactive power capability of a wind farm includes obtaining one or more real-time operating parameters of each of the wind turbines. The method also includes obtaining one or more system limits of each of the wind turbines. Further, the method includes measuring at least one real-time wind condition at each of the wind turbines. Moreover, the method includes continuously calculating an overall maximum active power capability and an overall maximum reactive power capability for each of the wind turbines as a function of the real-time operating parameters, the system limits, and/or the real-time wind condition. Further, the method includes generating a generator capability curve for each of the wind turbines using the overall maximum active and reactive power capabilities and communicating the generator capability curves to a farm-level controller of the wind farm that can use the curves to maximize the instantaneous power output of the wind farm.

Abstract: The present disclosure is directed to a method for protecting an electrical power system connected to a power grid. The electrical power system includes at least one cluster of electrical power subsystems. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid. The converter power path includes a partial power transformer. The electrical power system further includes a subsystem switch configured with each of the electrical power subsystems and a cluster transformer connecting each cluster of electrical power subsystems to the power grid. A cluster switch is configured with the cluster transformer. A controller is communicatively coupled to each of the plurality of electrical power subsystems. Thus, the controller monitors the electrical power system for faults, and if a fault is detected in the cluster, sends, via one of the subsystem switches or the power converters, a block signal to the cluster switch.
