摘要
随着电网中非线性器件使用的增多,电网中的谐波含量显著增加,会对电网的安全运行和用电设备的正常工作造成严重影响,为实时监测电网中各谐波分量,研发了基于CAN总线的谐波监测装置,给出了装置的数据采集、锁相倍频、AD转换和数据通信等模块电路,利用TI公司提供的FFT Library库函数进行FFT运算,完成了谐波的分析,并通过试验进行了验证。结果表明,该装置可行、有效,满足了设计要求。
With the increased use of non-linear devices in the grid, the harmonic content o{ grid increase significantly, that will lead to seriously impact on the safe operation of the power grid and the normal work of electrical equipment. For real-time monitoring power grid harmonic components, the high performance electric harmonic monitoring device is developed based on CAN bus. These modular circuits for data acquisition, phase-locked frequency multiplication, AD converter and data communication are also given. FFT is operated by using TI＇s FFT library functions to complete the analysis of harmonic and to verify by experiment. The results show that the device is feasible and effective, which meets the design requirements.
