| 摘 要： | 为了能够检测出电力系统中的谐波信息并能实时的调整采样频率使之与电网频率的同步,提出一种通过采样数据计算电网电压实际频率的方法,能够动态的调整采样频率,实现同步采样;经过基于DSP的实验验证,能够有效地减少因非同步采样造成频谱泄露的影响。算法具有实现简单、精度较高的优点。

| Abstract: | In order to detect the power system harmonic information and adjust sampling frequency along with grid frequency in time, this paper presents a real - time computation grid frequency method using sampling datum. This method can realize synchronous sampling through dynamically adjusting sampling frequency. The proposed method is verified by experiment prototype based on DSP. The experimental results show that the method effectively reduce the impact of non - synchronous sampling according to a leaked spectrum, this algorithm is simple and with high precision. |
