  • Patent number: 10074983
    Abstract: The technology is generally directed towards characterizing primary frequency response parameters (e.g., frequency response coefficient, inertia, damping, droop) for an interconnection, region, and power plant utilizing phasor measure unit (PMU) data captured during an event (e.g., a generation trip event) that causes an imbalance in the power grid system. Pre-processing of localized PMU based frequency measurements combined with system identification techniques fit the observed frequency response to estimate parameters such as system inertia, frequency response coefficient, turbine time constant, system damping and governor droop that characterize the interconnection-wide frequency response.

  • Patent number: 10066513
    Abstract: The invention relates to a method for operation of a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, and in which method the exhaust gas emerging from the at least one turbine is passed through a heat recovery steam generator (HRSG) in order to generate steam. The electricity production can be decoupled from the steam production in order to restrict the electricity production while the heat provided by steam extraction remains at a constant level. A portion of the inducted combustion air can be passed through at least one turbine to the HRSG without being involved in the combustion of the fuel in the gas turbine. This portion of the combustion air can be used to operate at least one supplementary firing in the heat recovery steam generator.

The pulverized coal burner furthermore has at least one core duct and at least one secondary duct. Air or oxygen flows through the core duct and the secondary duct, emerging at the core duct outlet and at the secondary duct outlet. The core duct outlet, the secondary duct outlet and the fuel duct outlet together form a burner outlet. The pulverized coal burner has at least one plasma ignition torch embodied integrally with the pulverized coal burner. The outlet of the at least one plasma ignition torch is arranged in the plane of the burner outlet or offset downstream in relation to the direction of flow of the pulverized coal.
