自励双馈同步感应发电机的分析与单片机控制

The Analysis of Self-Excited Doubly-Fed Synchronous Induction Generator and its Single-Chip Microprocessor-Based Control System

两极自励双馈同步感应发电机可做成高速工频发电机,供单独供电系统用。本文采用综合矢量法推导出双馈发电机的电磁转矩、有功和无功功率等,表明了该发电机具有类似同步发电机的性质;提出一套保证双馈发电机恒频、恒压的微机控制系统。

2-phase self-excited synchronous induction generator can be used as the high- speed commercial frequency generator for isolated supply system.By space vectors, the paper works out the expressions for electromagnetic torque,active and reactive powers,etc.,showing that the machine has the capability similar to that of conven- tional synchronous generator.The paper presents a microprocessor-based control system for constant-frequency and constant-voltage supply.
