摘要
针对电力系统现阶段存在无法利用原始系统的模型参数复现事故曲线这一问题,指出了系统频率动态仿真准确度的影响因素,如实际系统事故数据采集与预处理方法、系统模型搭建及参数辨识。分析了它们对频率动态过程的影响机理。概述了现阶段用于解决以上问题的手段。
Since the parameter of the original model fails to repeat accident curve at the present stage,this paper points out the factors influencing accuracy of electric power system frequency dynamic simulation,including practical system accident data acquisition and preconditioning and system model establishment and parameter reorganization,discusses the mechanism how these factors influencing frequency dynamic process and summaries means adopted at the present stage.
