Abstract

The paper presents a comparative study between two operating modes for a permanent magnet synchronous motor (PMSM) at variable speed, in order to obtain a better efficiency. The aim is to find the best operating mode for a pumped storage system supplied by variable renewable energy sources (RES) energy based source. The study includes several PMSMs with rated speed of 1000 rpm, from power ranged between 5 and 75 kW at variable speed. Through simulations the paper shows that the yield can be improved at low speeds.

永磁同步电机的效率在变速泵的应用

为了获得更好的效率，本文对永磁同步电动机在变速工况下的两种运行方式进行了比较研究。目的是寻找以可变可再生能源(RES)为基础的抽水蓄能系统的最佳运行模式。该研究包括几种额定转速为1000转/分的永磁同步电动机，功率范围在5到75千瓦之间。仿真结果表明，该方法可以提高低速下的成品率。
