摘要
Abstract
The digital suhstation technique has obtained rapid progress at home. Based on the key primary equipment, such as electronic instrument transformer, the paper introduced the principle of numerical integration algorithm, analyzed the cause of error in the measurement of rms and active power, and gave the formulas of truncated error, rounding error and synchronous error. The paper also simulated the process of non-synchronous sampling in electronic instrument transformers. The simulation result and theoretical analysis came to the conclusion that numerical integration algorithm can satisfy the high accuracy request on certain condition.关键词
