变频电源的组建及变频电动机加负载的试验方法的探讨

Discussion on the Formation of Variable-Frequency Source and the Test Method of Loading Variable-Frequency Motor

从理论上利用原动机驱动YR绕线转子电机,通过转子正序负序励磁做变频电源进行了讨论并论证可行性,同时利用变频发电机做陪试电机为变频调速电动机加负载的试验方法进行了讨论,为技术人员提供借鉴。

The method of driving YR wound-rotor motor by prime mover and taking positive and negative sequence excitation of rotor as variable-frequency source is discussed theoretically and it is workable by proving.At the same time,the test method of taking variable-frequency generator as coupled machine to load the variable-frequency adjustable-speed motor is discussed also.This can provide experience for technical personnel.
