摘要
通过理论分析和实验研究,证明了3相自励感应发电机单独带负载运行的情况下,要做到恒压恒频,必须满足随负载电流的变化相应地调节励磁电流的大小,并且励磁电流的增加(减少)量应该与负载电流的大小近似成正比,而且随负载有功电流的变化相应地调节转速,转速的增加(减少)量与负载有功电流的大小近似成正比。
Theoretical analysis and experiments proved following conclusions： When a 3-phase self-excited induction generator runs with loads, to realize constant voltage and frequency, it satisfy two conditions （ 1 ） Adjust exciting current with the changing load current and the increase （decrease） of exciting current should be proportional to load current approximately. （2） Adjust rotation speed with the changing of load active current and the increase （decrease） of rotation speed should be proportional to active current approximately
