摘要
运用相加滤波算法和半周期积分法对恢复电压的工频分量和自由分量的特征量进行详细的推导分析,并分析了自由震荡频率估算误差对判据性能的影响,由此提出了新的拍频判据,并通过PSCAD仿真实验对其进行了仿真验证。
This paper analyzes the characteristic features in detail of frequency components and free component of recovery voltage by filtering and half cycle integral method. Also, the frequency estimation error free concussion of influence on the performance of the criterion is analyzed. Therefore, a new beat frequency criterion is proposed and it is simulated by the PSCAD simulation experiment.
