摘要
针对变频电源特性,结合目前电参数测试方法,设计了基于双DSP的变频电源电参数同步测试系统,利用SD卡实现了大容量存储,利用双端口RAM实现了变频电源输入、输出端电气参数数据的交互。现场测试表明,系统测量精度较高,能分析3~21次谐波,为分析变频电源的性能提供了有效的数据,具有相当大的应用价值。
According to the characteristics, of variable frequency converter, combining the test method of electric parameters, this paper designed the variable frequency converter parameters synchronous test system based on dual DSP, realized the large capacity storage using SD card, realized the interaction of the variable frequency converter input, output terminal electric parameters data using dual-port RAM. The field test shows that, the system has high accuracy, can analyze 3 to 21 times harmonic, provide effective data for analyzing the performance of the variable frequency converter, and has the quite big application value.
