摘要
针对目前配电变压器数量众多、分散,并且缺乏自动化监测手段的特点,设计一种配电变压器在线监测终端,通过GPRS无线模块实现配电变压器运行参数的远程传输,达到实时监控的目的。通过充分挖掘LPC2132的数字信号处理能力,用汇编语言设计高效的快速傅里叶变换算法,以满足谐波分析的实时性要求,主要介绍终端的硬件构成、软件设计思想以及电能质量分析算法。
A type of online monitoring terminal for distribution transformer to meet the demand of real-time harmonic analysis was designed.By making full use of the ability of digital signal processing with LPC2132,a high-efficiency Radix-4 fast Fourier transform(FFT) algorithm with assembly code was designed.The terminal's hardware design,software design and energy electrical quality analysis algorithm were mainly introduced.
