摘要
针对在电力系统频率跟踪算法中推导过程复杂、计算量大等问题,提出了一种利用递推偏最小二乘法(RPLS)实现电力系统频率跟踪的新算法。该方法在递推过程中,采用滑动窗法更新数据,同时引入了适当的遗忘因子。仿真结果表明,该算法在电力系统频率跟踪中具有计算复杂度小,推导过程简单,频率跟踪收敛速度快,测量精度高的特点,其是电力系统频率跟踪中的一种新方法。
In view of the complex derivation and large amount of calculation of the power system frequency tracking algorithm, a new algorithm for frequency tracking of power system using a Recursive Partial Least Squares （RPLS） is proposed. The sliding window method is used in the recursive process to update data, and the appropri- ate forgetting factor is introduced. The simulation results show that this algorithm has small computation complexity in power system frequency tracking with simple derivation, fast convergence and high accuracy.
