论文首先阐述了基于同步发电机不控整流的消磁脉冲电源的原理及组成,接着研究了消磁工况下同步发电机的工作特性,求得了同步发电机定子电流的解析表达式,并采用数值逼近法计算出了定子电流瞬时值及相关参数,最后某消磁站的实验数据表明,理论计算结果和实验测量值相符,证明了数值计算方法的正确性。

The principle and composing of the deperming pulse power source based on synchronous generator-uncontrolled rectifier are expatiated in this paper , the characteristics of the synchronous generator for deperming are researched, the stator current＇s analytical formula of the synchronous generator are calculated, and the numerical approximation technologies are used to calculate the stator＇s instantaneous current and correlative parameter The experiment data of one deperming station show that the results of calculation and the data from experiment measure are wholly consistent, and the numerical calculation method is effective.
