    针对电力系统有效值测量存在的不同步误差及量化误差问题，分析了卷积窗加权算法克服不同步误差的优势，推导出基于加权算法下量化相对误差关于采样频率和量化位数的解析式，最后对结论进行数值模拟加以证明。

    Aiming at the problem of non-synchronous errors and quantization errors in effective value measurement of power system. The dominant of convolution window weighting algorithm overcoming non-synchronous errors is analyzed,and analysis formula of weighting algorithm-based quantization relative errors is deduced which is with respect to sampling frequency and quantization length. The result is proved by numerical simulation.
