基于数字化计量体系的有限字长效应分析
Analysis of Finite Word Length Based on Digital Metering
Abstract:With the rapid development of digital substation, digital metering is getting more widely used. This paper based on finite word length in digital substation system, explores the errors caused by the quantization of AD conversion, filters coefficients and digital operation, and combined with MATLAB, the paper makes a comprehensive analysis of these factors’ influence on overall accuracy.
