基于试验的炼化企业电力系统静态负荷模型参数辨识

Parameter Identification of Static Load Model for Power System of Refinery and Chemical Enterprise Based on Experiment

炼化企业电力系统负荷建模是一项重要的基础性研究。通过现场实测的数据,建立误差函数寻优,辨识出静态负荷的多项式模型和幂函数模型的未知参数。拟合曲线的评价指标证实了通过稳态试验法建立的静态负荷模型可行和有效。

Power system load modeling for refining and chemical enterprises is an important basic research.Based on the data measured on site,the error function is established to optimize,and the unknown parameters of the polynomial model and exponential model of static load are identified.The evaluation index of the fitted curve proves that the static load model established by the steady-state test method is feasible and effective.
