Parameter Identification Method of Turbine Speed Governor System Based on Power Grid Model
To address the difficulty in automatically identifying model parameters of turbine speed governor systems in power system simulation software such as PSD-BPA and PSASP,which requires manual verifi-cation and involves substantial workload,this paper establishes a parameter identification model for turbine speed governor system that considers grid equipment.This model is based on a single machine infinite sys-tem model and utilizes MATLAB simulation platform and the model parameters are identified by using a nonlinear least squares algorithm.The simulation example shows that the parameters identified using MAT-LAB produce identical results when simulated in BPA software,confirming the equivalence of the simula-tion model proposed in this paper with the BPA simulation model.Utilizing the proposed model can signifi-cantly reduce the manual verification work required for BPA,enhancing the effectiveness of model parame-ters and the efficiency of governor system modeling tasks.
