| 摘 要： | 针对目前常见的检测方法中控制电路过于复杂的问题,文章提出采用以自适应噪声对消技术的神经元电力谐波动态检测方案。采用最小均方(LMS)算法,获得所需的检测谐波信号,利用高精度微型互感器实现信号采集,由DSP实现对电力谐波的动态检测,利用CAN总线实现数据的高速上传给上位机,完成谐波数据的综合处理。该系统已成功地在河南中孚铝厂投入运行,检测精度达到国家标准,具有较高的推广价值。

| Abstract: | The ordinary control circuits for detecting electric harmonics are complicated.To solve this problem,the paper introduces a detection scheme using self-adaptive noise cancellation neurons.In this method,the Least Mean Square(LMS) algorithm is adopted to obtain detection signal,the high-precision micro-transducer is used to sample signal,DSP is used to detect the harmonics,CAN bus is used to transmit data,and PC is used to process the data.This system has been put into use successfully in Zhongfu Aluminum Plant in Henan province,and its detecting precision meets the national standard. |
