摘要
导出了工频电参数测量中非同步采样时电压、电流和功率的准确误差公式,设计了低通滤波器,从而降低了非同步引起的误差仿真计算表明,上述措施计算简单。
The error formulas for voltage, current and power on asynchronous sampling in the test system are derived, and the filter is designed to diminish the error. Simulating result shows simplicity and efficiency of the present method.
