交流电力功率智能传感器粗信号处理

摘要

In order to ensure the accuracy and timely reliability of AC electric power measurement, the article gives the bold signal processing method of intelligent sensor in AC power test. It took the minimum error of the sum of square as the criterion, estimated the based on the linear model according to observation data, used the least square characteristic parameters to estimate die initial sampling point of AC voltage and current values, at lasts got the AC electric power parameters.%为了保证交流电电力功率测试的精度和及时可靠,本文阐述了智能传感器的粗信号在交流电力测试中的处理方法.以误差的平方和最小为准则根据观测数据估计线性模型为根据,使用最小二乘特征参数法,估算了交流电的电压和电流值的初始采样点,可以得到交流电力的功率参数.
