摘要:本文介紹了異步電機(jī)雙饋調(diào)速的原理,并用Matlab構(gòu)建出雙饋調(diào)速系統(tǒng)模型。其中轉(zhuǎn)子繞組用交-交變頻器供電。文中指出了Matlab仿真庫(kù)中的異步電機(jī)模型與變頻器連接時(shí)存在不匹配的問題并提出相應(yīng)的辦法取得了較好的效果。用該模型對(duì)一實(shí)例進(jìn)行了仿真,仿真結(jié)果與實(shí)際運(yùn)行情況非常吻合,驗(yàn)證了模型的正確性。該系統(tǒng)模型對(duì)于研究此類雙饋?zhàn)冾l調(diào)速系統(tǒng)有一定的參考價(jià)值。

Abstract:The principle of double-fed motor speed regulation is introduced, and a simulation model is built with Matlab software. In the simulation the motor model in Simulink can not be connected directly to the cycloconverter model. This problem is solved by adding an ideal transformer model between them. The system model is used to simulate the real case. The simulation result agrees with the real one and the correctness of this system model is verified. So there are some values for studying similar questions.
