摘要: |
基于功率响应特性辨识汽轮机调节系统参数。采用简易模型克服了辨识算法中难以实现的发电机建模问题。通过分析参数对机组功率特性影响的关联性,对辨识流程和优化目标函数进行了设计。再以先进数值计算方法作为辨识手段辨识得到模型参数。利用PSASP对辨识结果进行仿真并与实测对比,结果表明:新方法所建模型仿真值与实测值相当接近,所建立的汽轮机调节系统模型能够较为真实地反映机组实际的响应特性,说明该方法正确有效。与原有辨识方法相比,实现了对模型参数的更加准确辨识。 |

Abstract: |
The parameters of steam turbine governing system based on power response characteristics are identified. A simplified model is adopted to overcome the difficulty of generator modeling. The identification process and optimization objective function are designed by analyzing the relevance of the influence of parameters on the power characteristic. Then using an advanced numerical method, the parameters of model are obtained. The simulative results of identification are compared with the measured value by PSASP, which show that the simulation results of the model built by new method are close to the measured value, and the steam turbine governing system model built in this paper reflects the actual response characteristics. The correctness and effectiveness of the new method are proved. Compared with the original identification method, the new method can realize more accurate identification of the model parameters.
