Patents by Inventor Mario Joao Kumula

Mario Joao Kumula has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8694172
    Abstract: Systems and devices for controlling power generation are provided. One system may include an electrical generator controller. The controller may include a filter component, a frequency response schedule component, and a rate limiter component. The filter component may receive a power grid frequency signal and output the frequency signal when the frequency signal is outside a frequency band. The frequency response schedule component may determine an ultimate target power contribution using the filtered frequency signal, the ultimate target power contribution representing an ultimate amount of power contribution that the electrical generator should provide in a primary frequency response. The rate limiter component may determine an immediate target power contribution signal that varies over time and approaches the ultimate target power contribution. Thus, the controller may control the approach rate and/or arrival time, and so forth, of the primary frequency response to a power grid frequency disturbance.

  • Patent number: 8463451
    Abstract: Systems and methods for monitoring power generation are provided. For example, such a system may include a gas turbine, an electrical generator coupled to the drive, a controller coupled to the gas turbine, and a compliance monitor. The gas turbine may generate a torque, and the electrical generator may provide power to a power grid based on the torque. The controller may cause the gas turbine to vary the torque in response to a frequency disturbance occurring on the power grid. The compliance monitor may determine whether the response to the frequency disturbance complies with a specification for the response.
