摘　　要：非同步采样测量计算误差在微机电量变送器电参量测量误差中占了主要成分,有必要采取有效措施减少该测量误差。对此,采用不同的采样方法对电路中的电压有效值及其有功功率进行仿真计算,以验证准同步采样测量算法在微机电量变送器电参量测量的有效性和消除非同步采样测量误差的必要性。The measuring errors of electrical parameters under the asynchronous sampling is main parts of the measuring errors in electrical quantity transducers,so it is essential to take effective measures to reduce its measuring errors.For this reason,it was emphasized to interpret the basic principle of the measuring algorithm under quasi-synchronous sampling and its digital processing ways.After making simulation on the algorithm,it proved that it could be effective to improve the measuring precision of the electrical quantity transducer.
