双馈同步感应发电机的运行性能分析

Analysis of the Doubly Fed Synchronous Induction Generator

本文分析了自励和他励双馈同步感应发电机的运行性能。用综合矢量法推导出教学模型,并用绕线式异步电动机改制成定、转子绕组有效匝数接近相等的发电机模型机。利用数学模型计算了自励式的外特性、调整特性及三相突然短路电流,并对他励式进行稳定性分析。计算结果与模型机试验结果吻合较好。

This paper explores the performance of the self excited and external-excited doubly fed synchronous-induction generator.The mathematical model has been worked out and the proto-type machine has been built with the effective number of turns of the stator and rotor windings nearly equal to eliminate the circulating current,With the mathematical model,the external characteristic,regulation charact- eristic and sudden short-circuited current of the self excited machine are calculated and stability analysis of the external-excited machine is carried out.The computed results show good accordance with the test data of the proto-type machine.
