摘　　要：电压有效值和频率是衡量军用电站供电质量的重要指标。他们的计算结果精度越高,我们就能越准确的评估电站性能。对非同步采样数据的合理处理可以很好的减少非同步计算误差。详细介绍了一种利用军用电站采样数据计算信号频率和电压有效值的方法,通过对"过零点"的拟合,很好的增强了信号频率和电压有效值的测量精度。最后在MATLAB环境下对介绍的算法进行了仿真,并且进行了详细的误差分析。Voltage RMS and frequency are important index that indicate quality of power supply of military power station. We can accurate assessment of power plant, only if their calculation results are accurately. The reasonable calculation method of asynchronous sampling data can effectively reduce the error of asynchronous sampling. The article gives a method of extracting signal frequency and voltage RMS from sampling data of military power station. According to zero crossing fitting, the algorithm enhances the accuracy of the signal frequency and voltage RMS. The algorithm is verified in MATLAB and the article analysis the error.
