交流内燃机车柴油机变频启动控制方法研究

Research on Control Strategy of Variable Frequency Starting System for Diesel-engine of AC Diesel Locomotive

提出一种基于转子磁场定向的功率因数近似为1的同步电机矢量控制方法,并将该控制方法应用于并励励磁同步发电机启动柴油机系统中。试验验证,其控制效果较好。

It proposed a vector control method,following which approximate unit power factor is got,based on the rotor flux oriention for the synchronous machine.The method was employed to control the excitation synchronous generator used in the starting system for dieselengine.The results of experiment show that the performance of the proposed control scheme is good.
