Technical Field
[0001] This invention belongs to the field of gas turbine control technology, specifically relating to an intelligent primary frequency controller and control method for gas turbines. Background Technology
[0002] Gas turbines are widely used in ground-based power generation, grid peak shaving, and ship propulsion. The working cycle of a gas turbine includes three basic processes: air compression, combustion, and expansion. First, air is drawn in and compressed by the compressor, then enters the combustion chamber to mix with fuel and burn, producing high-temperature, high-pressure gas. Finally, this gas expands in the turbine, doing work and driving the turbine to rotate, thereby driving the generator to produce electricity. The gas turbine controller is the core component of the gas turbine control system, responsible for monitoring and adjusting the operating status of the gas turbine.
[0003] Chinese patent CN118068715A discloses a method and apparatus for constructing a gas turbine speed controller model. This method considers the cooling extraction volume during the modeling process, resulting in a gas turbine model that better matches the actual operating conditions of the unit and has higher reliability. The initial speed controller model constructed based on the LADRC structure has short settling time, low overshoot, and better disturbance rejection. The speed controller model is obtained by using the gas turbine model and a global search algorithm to tune the parameters of the initial speed controller model. However, existing methods cannot take into account the fluctuation of the grid frequency when constructing the gas turbine model, which makes it impossible for the gas turbine model to immediately adjust the gas turbine load and ensure the stability of the grid frequency. To address the above problems, we propose an intelligent primary frequency control controller and control method for gas turbines. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent primary frequency control controller and control method for gas turbines. This solves the problem that existing methods cannot take into account fluctuations in the power grid frequency when constructing gas turbine models, thus preventing the gas turbine model from immediately adjusting the gas turbine load and ensuring the stability of the power grid frequency.
[0005] Existing methods for constructing gas turbine models cannot account for fluctuations in grid frequency, thus preventing the gas turbine model from immediately adjusting the gas turbine load to ensure grid frequency stability. To address this issue, we propose an intelligent primary frequency regulation controller and control method for gas turbines. In short, the control method first establishes a gas turbine simulation model using basic parameters of the gas turbine and grid infrastructure. Then, it simulates and executes the gas turbine simulation model, which outputs at least one set of frequency regulation fluctuation coefficients. Based on a fuzzy clustering algorithm, it calculates the frequency regulation probability value corresponding to discrete frequency regulation scenarios. Then, based on the frequency regulation fluctuation coefficients and frequency regulation probability values, it constructs and trains a sub-Bluerband frequency regulation model. Finally, the sub-Bluerband frequency regulation model uses a load suppression algorithm to allocate the primary frequency regulation output of the gas turbine. In this embodiment of the invention, when constructing the gas turbine simulation model, the basic parameters of the gas turbine and power grid facilities are combined. This allows the fluctuation of the power grid frequency to be considered when the gas turbine simulation model is executed, ensuring the frequency regulation efficiency and success rate of the split-bulb frequency regulation model when the power grid frequency fluctuates. This overcomes the problem that existing methods cannot take into account the fluctuation of the power grid frequency when constructing the gas turbine model, which makes it impossible for the gas turbine model to adjust the gas turbine load immediately and ensure the stability of the power grid frequency.

[0134] In summary, this invention provides an intelligent primary frequency control controller and control method for gas turbines.
