摘要
本文提出不良数据检测和辨识新算法——递归量测误差估计辨识法(RMEEI法)。该算法利用线性递推公式计算量测集变化后状态变量、残差及其方差的新值,避免了状态再估计和计算残差灵敏度矩阵,大大提高了计算速度。文中给出了算法公式,并给出评定算法辨识性能,计算速度等方面的计算结果,还给出了本算法在东北电网控制中心EMS中实时运行的情况。
A Recursive Measurement Error Estimation Identification (RMEEI) method for dad data analysis in power system state estimation is proposed in this paper. A set of linear recursive formulae are used to update state variables, residuals and their variances in the identification process. Neither state re-estiomation nor residual sensitivity matrix is needed. Digital tests are carried out and results are given out. A real-time implementation of the method in the EMS of the control centre of the Northeast China Power System is reported.
