高压大容量同步电动机启动的应用研究

Application Research of High Voltage and Large Capacity When Synchronous Motor Starting

以陕西省黄金峡水利枢纽工程7台13.8KV/18.5MW同步电动机为案例。依据高压同步电动机启动要求,对泵站不同启动方式进行计算,分析对系统母线的影响,在Matlab中对黄金峡泵站18.5MW同步电动机静止变频器启动过程进行建模仿真,得到系统启动过程中主要物理量的变化曲线,为黄金峡泵站启动方式的选择提供理论依据。

Synchronous motors of shaanxi pumping irrigation project— Huangjinxia pumping stations（7×18.5MW 13.8kV）are taken as the research object.In accordance with the startup request of high voltage synchronous motor,different starting ways of pumping station are calculated.Then and the influence of system is analyzed and evaluated.The feasible advice for the synchronous motor starting method is proposed,according to the results and actual project requirements,static freguency converter starting proces is modeled and simulated susing Matlab.
