智能电能表计量可信性分析方法研究

Reliability analysis method of power meter measurement

智能电能表现场运行环境日益复杂,其计量准确性和可信性受到越来越大的挑战,有必要对电能表在长期运行中各项指标情况进行研究。本文利用高斯正态分布理论分析电能表误差分布概率的置信度,提出一种能全面反应电能表准确性的组合误差指标概念,实现对智能电能表计量的可信性定量分析及评价。该方法对电能表计量可信性、可靠性及一致性的综合评价,具有一定的参考价值。

Intelligent electric energy meter running environment of the scene becomes more and more complicated, the measurement accuracy and credibility are more and more challenges, it is necessary to form of energy in the long run the indicators of the study. In this paper, the Gaussian distribution theory analysis of electric energy meter error distribu-tion probability of confidence, a can comprehensive active electric energy meter accuracy composition error index con-cept, the implementation of intelligent electric energy meter measuring the credibility of quantitative analysis and evalu-ation are proposed in this paper. This method has some reference value for the comprehensive evaluation of the reliabili-ty, reliability and consistency of the electric energy meter.
