摘要
针对电力系统中电能质量问题的分析,为强化理论结合实践,锻炼学生的仿真实验能力,构建了基于多信号处理方法的电能质量虚拟仿真实训平台。该平台采用以数字信号处理器DSP为核心构建的下位机的数据采集系统,上位机在Lab VIEW和Matlab开发环境下,针对不同的电能质量问题,选择小波变换、S变换、HHT变换等不同的信号处理方法,实现电能质量问题的特征提取和分析。通过合理利用和有效管理该实训平台,能够开发多种实验项目,优化配置实验室资源,改革人才培养模式和考核方式,全面提高学生对硬件设计和软件仿真的综合实践能力。
According to power quality problem in power system,this paper develops the virtual simulation and training platform of power quality analysis based on many kinds of signal process methods in order to strengthen combination of theory and practice and to train students ＇simulation and experiment ability. The platform uses DSP as the core to construct lower machine of data acquisition system,selects different signal process methods such as wavelet transform,S transform,HHT transform and so on according to different power quality problems,and realizes feature extraction and analysis of power quality problems in upper machine of Lab VIEW and Matlab environment. Through reasonably using and managing the platform,it can develop many experiment items,optimize laboratory resources,reform personnel training mode and examination method and completely promote students＇ comprehensive experimental ability to hardware design and software simulation.
