为了能够实现配网谐波的远程在线监测,实现配网谐波远程在线装置的设计,通过信号采集装置实现线路中电压及电流互感器的信号的收集,将收集到的信号转变为数字信号,使用FFT模块中的内部IP核实现傅里叶变换,从而得到谐波数据,最后利用GPRS模块实现监测数据到供电主控计算机的传输。将设计的配网谐波远程在线监测装置应用到某厂高压配电室中,表示此装置能够有效满足配网谐波在线检测需求,能够实现工厂谐波含量的监测,并且将监测到的结果远程传送到主控计算机中,实现配网谐波的远程在线监测。

in order to realize the remote online monitoring of the distribution network harmonic, the design of the network harmonic remote on-line device is realized. Line was achieved by signal acquisition device of voltage and current transformer signal collection ,the collected signal into digital signal, using FFT module internal IP core of Fourier transform, harmonic data is obtained, and then through the GPRS module transmission monitoring data in the power supply main control computer. The design of distribution network harmonic remote online monitoring device is applied to the high voltage transformer room at a factory, says the device can effectively meet the demand of distribution network harmonic on-line detection, can achieve harmonic content monitoring factory, and will monitor the results of the remote transmission to the main control computer,realizes the distribution network harmonic remote online monitoring.
