The Set of AC-AC Direct Variable Frequency and Controlled Speed of Synchronous Generator Supplying Squirrel-Cage-Rotor Induction Motors

本文提出了一种新型的交-交同步发电机-异步电动机组(TF·AD),将节能多速异步电动机的分级变极调速法与柴油机-发电机组的平滑变频凋压技术结合起来,以展宽交-交 TF·AD 组之调速比,并分析了 TF·AD 组的主要控制规律及其机械特性.

A new type of AC-AC generator-motor set is presented.In this paper,the first method is that the speed of the multi-speed induction motor of economizing on electricity can be changed step by step and the second method is that the frequency or voltage of the diesel engine generator can be controlled smoothly.Com- bining the two methods mentioned,we get the result to increase the speed ratio of the generator-motor set.In addition,the main controlling theory and the torque-speed characteristics are explained.
