摘要
提出了以实测数据信号扰动能量为基准的动态变异率(DVR)来表征动态仿真的误差水平,并对一些仿真算例误差评定给出了具体的方案。对某变电站两条出线的负荷数据仿真准确度评定,证明所提的方法是快捷有效的。
The dynamic variation ratio (DVR) based on the measured signal energy is proposed to denote the error level of dy- namic simulation, and the detailed error evaluation scheme is als0 proposed for the vast simulation cases. The evaluation of simulation accuracy for load data of two feed lines at a substation proves that the proposed method is convenient and valid.
