海上平台潜油电机变频器谐波及其抑制

Harmonic and Inhibition on Offshore Oil Platform Electric Submersible Motor Frequency Inverter

随着潜油电机变频器在海上石油平台电力系统中广泛应用,带来了变频生产、电机调速控制等好处,同时也给海上石油平台电力系统带来了谐波污染问题。从变频器谐波产生原理的基础上,结合某石油井口平台,实例计算谐波电流和谐波电压。另外分析了谐波的抑制措施,有源滤波器对谐波滤除和抑制效果。

With the submersible motor inverter widely used in offshore oil platform power system. It brought not only the frequency conversion production and control motor speed,but also to the offshore oil platform power system bring the problems of harmonic pollution. This paper from the inverter harmonic generation principle, combining with an oil wellhead plat- form, instance to calculate of harmonic current and harmonic voltage. Besides the paper analy- sis the harmonic inhibition method, the active filter for harmonic filtering and inhibitory effect.
