基于恒励磁电流的同步电动机强励方法

A reinforced excitation method based on the constant excitation current of synchronous motor

为避免同步电动机失步而引起大量气体排放,从提高励磁系统稳定性的角度出发,阐述了强励保护的重要性,分析了强励的原理和实现的方式,指出了传统开环强励方法的弊端,提出了恒励磁电流强励措施,并从理论和实践角度验证了新措施的正确性。

In order to avoid large amount of gas emission caused by out of step synchronous motor, the strong excitation pro tection was discussed from improving stability point of view. The principle and realization ways of forced excitation were ana lyzed. The defect of traditional open loop force excitation method was pointed out. Constant excitation current strong excitation measures were made. The correctness of new measures are verified by theory and practice.
