随着电力电子设备在油田配电系统中的广泛应用,配电网的波形畸变日益严重,进而危害到电气设备的正常运行及电力系统的可靠性。分析了油田配电系统的特点,认为谐波产生的根本原因是钻采系统与油气集输系统采用大量非线性负载所致,其危害主要是降低设备的使用寿命和工作效率;分析了当前主要采用的的几种谐波治理方法,包括安装电抗器、安装无源电力滤波装置、安装有源电力滤波装置、安装有源滤波+无源滤波装置等的特点,并对几种滤波技术进行了对比;介绍了采用有源滤波器实现电力系统谐波动态抑制的发展过程,并对油田配电系统谐波动态抑制技术的发展进行了展望。

With the wide application of the power electronic equipment in the oilfield electric distribution network, the waveform distortion of the grid becomes increasingly serious and damaging to the normal operation of the electrical equipment and the power system reliability. Based on the characteristics of the oilfield electric distribution network and the basic theory of the harmonic analysis, this paper gives a brief introduction to the causes and damages of harmonic waves in the oilfield electric distribution system, the harmonic control method and the filtering techniques are compared, and the development process of the Harmonic Dynamic Suppression technology using the active filter in the oilfield electric distribution system is discussed. Finally, the prospect of the development of the Harmonic Dynamic Suppression in the oilfield electric distribution system is commented.
