Reliability Analysis on Clock Battery of Smart Meters Based on Weibull Distribution
As a key component of smart meter,the clock battery quality directly affects the reliability and stability of the smart meter.Targeting the situation that a large number of the smart meter fails due to the clock battery undervoltage,the paper expounds a reliability analysis method of the clock battery of the smart meters based on Weibull distribution.The reliability model of the clock battery is established by batch based on the historical data of the smart meter running on site.The clock battery quality of the smart meter is evaluated quantitatively according to the area enclosed between the reliability function and the coordinate axis.This method can analyze the clock battery reliability of the smart meters in large quantities,improving the condition monitoring level of the smart meters,early warning the abnormal condition and faults of batch of smart meters,and reducing the cost of power grid operation and maintenance.
