| 摘 要： | 将离散小波变换应用于电力系统的网络分析，推导出小波域的节点电压方程式，得到了小波潮流算法，并且通过在小波分解时改变电力信号的边缘延拓方式，摒弃了以往仿真算法中必不可少的状态初值要求，使算法更加实用。与电力信号的小波时频分析算法相结合，为电弧炉供电系统中滤波器组参数的设置提供了有效手段。 |
| 关 键 词： | 小波分析 电能质量 谐波潮流 |

| Abstract: | A m ethod for harm onic power flow in power system ,which analyzes networks with discrete wavelet transform and then builds nodal voltage equilibrium equation for system simulation,is presented in this paper. It avoids the requirement of initial state values of components with different border extension styles for the variation of power signals in wavelet transform . Combining with time- frequency analysis method that based on wavelet transform,the m ethod can adjust param eters of filter bank of power supply system for arc furnace effectively. |
| Keywords: | wavelet analysis electric energy quality harmonic power flow |
