| 摘 要： | 基于正交变换,提出了一种新的电网频率跟踪方法.针对两种模型进行仿真,表明该方法能够较为精确与快速地跟踪电网频率,尤其针对突变频率的信号,具有较好的跟踪效果;同时算法克服了同步采样条件的限制,通过迭代,在不同初始频率下均具有较好的收敛性.

| Abstract: | Based on orthogonal transform,a new method of tracking power grids frequency has been provided.Simulations with respect to two models,prove that the method can track the frequency accurately and instantly,and have the preferable effectiveness on the abruptly fluctuating-frequency power signals,at the same time,this method overcomes the constraint of synchronous sampling and has the better astringency with different initial frequency. |

| Keywords: | power grids frequency orthogonal transform tracking method |
