| 摘 要： | 针对实数域对称分量估计实时处理效率低的问题，提出了一种基于复数Kalman滤波的电力系统正序谐波对称分量估计算法。利用对称分量理论获得了三相电力系统正序瞬时值对称分量，通过相应变换获得复数数字信号模型，根据需要估计的正序谐波对称分量，获得相应的状态方程和观测方程，利用复数Kalman滤波算法实现了正序谐波对称分量估计。仿真实验结果表明，该算法可实时在线实现正序谐波对称分量估计。

| Abstract: | The paper presents a new complex Kalman filter based method to estimate positive symmetrical (PS) harmonic components of power system.The theory of symmetrical component was used to obtain instantaneous PS component，and the complex numerical signal model of three phase power system was obtained by using transformation.State and observation equations are obtained according to the PS harmonic component to be estimated.The PS harmonic components were estimated by using complex Kalman filter.The simulation results show that the method presented in the paper can estimate the PS harmonic components accurately in real time. |
