【摘要】 本文通过分析国内外电能质量检测装置及分析算法的发展现状,研制了一种基于DSP技术的新型电能质量分析装置。 论文介绍了电能质量的相关概念、衡量指标及其数学分析方法,并且对相关算法运用Matlab中的Simulink软件进行了建模仿真;系统硬件由AD73360为核心的数据采集子板和TMS320C5402 DSK构成;系统软件包括底层的驱动程序和以快速傅立叶变换(FFT)为核心的分析算法程序。 所研制装置实现了对三相电压和电流信号的采集,以及对于所得数据的谐波、功率、电压波动、闪变、频率偏差和三相不平衡等电能质量问题的分析。

【Abstract】 By analyzing the present situations of the electric power quality monitoring equipments and algorithm home and abroad, aiming at the demand of power department, A new surveillance device based on DSP(Digital Signal Processing)technology is developed.This paper analyzes the concepts of power quality and its correlative algorithms and modling firstly. The hardware structure is made up of AD73360 (A/D) and TMS320C5402 DSK at the demand of practical applications of power department.The software includes the drive program and the program of correlative algorithms.The surveillance device can get the data of sampled three phases voltage and current signals,and the data is analyzed by DSP using the fast Fourier transfonn (FFT) algorithm about the harmonic,the aberration of voltage waveform, voltage fluctuation, flicker, deviation of frequency and three-phase unbalance and so on.
