Real-Time Performance Evaluation of Primary Frequency Regulation for Flexible Operation of Coal-Fired Units

In this paper, a model of the turbine and its regulation system of a typical coal-fired unit is built based on the Matlab/Simulink simulation platform, including the electro-hydraulic regulation system model, the electro-hydraulic servo mechanism model and the turbine model, and the scientific validity of each model is verified separately. At the same time, the overall model was simulated and verified under grid-connected operating conditions, and the reliability and accuracy of the model in the evaluation of the primary frequency regulation performance of the unit were finally verified.
