提高电能计量准确性的方法

Research on methods to improve accuracy of electrical energy measurement

电能计量是将采样值输入到模数转换器,实现采样值的数字化。输出模块响应于控制电路,用于显示、记录或发送计算结果。定时电路使预定采样定时器间隔超时。在间隔结束时,控制电路产生新的采样值并重置定时电路。定时电路构造成识别控制电路的多个故障模式并响应于此复位控制电路,从而提高计量系统的可靠性。本研究主要探讨提高电能计量准确性的方法。

Energy metering is the input of sampled values to an analog-to-digital converter to digitize the sampled values.The output module responds to the control circuit for displaying,recording or sending calculation results.The timer circuit times out the predetermined sample timer interval.At the end of the interval,the control circuit generates a new sample value and resets the timing circuit.The timing circuit is configured to recognize a plurality of failure modes of the control circuit and respond to the reset control circuit,thereby improving the reliability of the metering system.This study mainly discusses ways to improve the accuracy of energy measurement.
