摘要
由于船用逆变器的输入电力主要来源于发电机组,谐波含量较高,谐波严重威胁电力环境,甚至威胁到航行安全及船员生命安全,所以在船用逆变器必须对谐波进行处理。该文介绍了一种简化了卡尔曼滤波算法,使其在数字控制系统中既用较为简单的实现算法保证了运算的精度,又起到了滤波的效果,并通过实际的试验数据对该滤波算法进行了验证。
Because of the input electric power of inverter is generator unit on the ship. scale of harmonic is higher.The harmonic threaten the safety of seaway and seaman＇s life,so we must deal with the harmonic of inverter on the ship. In this paper,we introduce a simplify Kalman filtering algorithm,it achieve briefness,and effect of filtering is marked.This Algorithm is proved by practical test data.
