摘　　要：在实际应用中,人们往往只注意到变频调速(VVVF)的节能效果,而忽视了由变频器引起的谐波危害。针对漠北油田转油站外输泵变频调速系统中的高次谐波危害,分析了高次谐波产生的原因,通过对电压、电流波形的观测和数据的记录比较,确认了故障是由变频器带来的高次谐波引起,提出了合理的解决方案,成功地消除了谐波危害,确保了漠北油田的安全生产并指出了使用变频调速技术的注意事项,具有较高的工程指导价值。In engineering, the power-save effect of VVVF is often noticed, but the high order harmonic brought by transducer is ignored. Aiming at the high order harmonic harm of the transport pump in the production of Mobei oil field, the reason of the production of high-order harmonic is analyzed. Based on the observation of voltage and current wave and the compare of the data, the fault by the high-order harmonic brought by transducer is affirmed, the reasonable solution is stated, the harmonic harm is successfully eliminated, the safety prodt,ction of Mobei oil field is insured. And the notice pointed out has high direction value in engineering.
