为了验证异步电机变频调速在输油站应用的实际应用效果，进行了变频调速泵(离心泵)的工作特性分析、运动流体的能量分析和电机功率因数的分析。然后，对某输油站串联安装且同时运行的变频离心泵和非变频(工频)离心泵近一年的运行数据进行分析验证。理论分析和数据统计分析的结果一致。结果表明异步电动机变频调速(降频)运行后，节能效果显著，且输油管道压力调节范围更大，提高了电机的功率因数。

In order to verify the practical application effect of asynchronous motor variable frequency speed regulation in oil transportation station, the working characteristics of the variable frequency speed regulating pump (centrifugal pump), the energy analysis of the moving fluid and the power factor of the motor are analyzed. Then, the operation data of the frequency conversion centrifugal pump and non-frequency conversion (power frequency) centrifugal pump installed in series and operated at the same time in an oil transportation station are analyzed and verified. The results of theoretical analysis and statistical analysis are consistent. It is proved that the variable frequency speed regulation (frequency reduction) of asynchronous motor has remarkable energy saving effect, the oil pipeline pressure regulation range is wider, and the motor power factor is improved.
