高压大功率注水电机安装变频器可行性分析

Feasible Analysis of Installing Frequency-changing Units in the Electric Motor of water-injection with High-voltage & High-power

高压大功率注水电机是油田耗电大户，如何通过技术改造降低其电耗是各有关单位所普遍关心和重视的问题。以孤东采油厂为例，对高压大功率注水电机实施变频改造的必要性、可行性及经济效益进行了全面分析。认为随着高压变频技术的日臻成熟和价格的逐步下降，可以推广应用。

The electric motor of Water-injection with high-voltage & high-power is a main power consumer in oil fields. HOw to decrease its electrical consumption through teChnological reform is a queStion which each compnay has concerned and attached gnat importance. The necessity, feasibility and economic benefits for mplementing the frequency-changing reform of the electric motor have been comprehensiVely analyzed taking Gudong Oil Production Company as an example. Wb the maal of high-voltage at frequency-changing tectriloss day-by-day and the decrease of price step-by-step, the unit can be popularized and applied.
