摘要:雙饋電機是一種結構簡單、堅固可靠、異同步通用的電機,可以實現異步、同步、雙饋等多種運行方式。具有變頻器容量小,功率因數可調等特點。既可作為電動機運行用于交流調速傳動系統, 也可作發電機運行用于變速恒頻恒壓發電系統,由于系統控制方法的靈活性與多樣性,使得雙饋電機調速在在風機和泵類機械的節能調速系統及變速恒頻的水力和風力發電系統中具有廣闊的應用前景。      本文對雙饋電機控制系統進行了較為深入的研究, 首先分析雙饋電機基本結構、運行原理的基礎上,推導和建立了雙饋電機調速的數學模型,然后就雙饋電機目前通用模型,定、轉子坐標下的雙軸模型進行了分析,對轉子雙軸模型進行了深入研究,利用 matlab/simulink 仿真軟件建立了雙饋電機調速系統仿真模型,并對雙饋運行模式進行了仿真研究,驗證了雙饋電機的運行機理和性能特性。系統模型建立在以定子電壓定向的同步旋轉坐標軸系中, 可以實現雙饋電機轉速與無功功率的解耦控制。仿真結果表明,該控制原理和方法比較適用于雙饋電機的控制系統,能有效的對電機的轉速進行動態控制,具有較好的動態性能。本文所完成的工作,對于雙饋電機調速系統的發展具有現實意義,對雙饋電機及其系統進一步實用化研究奠定了基礎。 35962

The Design For Variable Speed System of Doubly-fed machine
Abstract Doubly-fed motor is a kind of simple structure, strong reliable, different generic synchronous motor, can realize  asynchronous, synchronous, doubly-fed a variety of ways to run and so on.Has a small capacity of the inverter, adjustable power factor, etc.Can be used as a motor to drive running for ac speed regulation system, also can make generator operation used in variable speed constant frequency constant pressure generating system, the flexibility and persity of the system control method, makes the doubly-fed motor speed control in fan and pump mechanical energy saving speed regulation system and the variable speed constant frequency wind power and hydroelectric system has broad application prospects. In this paper, thorough research the doubly-fed motor control system , first of all, analysis of doubly-fed motor on the basis of the basic structure, operation principle, derivation and established the mathematical model of doubly-fed motor, the universal model, and then doubly-fed motor, the rotor coordinates of biaxial model  was analyzed, and the rotor biaxial model were studied, using matlab/simulink simulation software to establish the simulation model of doubly-fed motor speed regulating system and the simulation for the operation mode of doubly-fed, verify the effectiveness of the doubly-fed motor operation mechanism and performance characteristics.System model based on to the synchronous rotation axes of stator voltage, can realize the doubly-fed motor speed and reactive power decoupling control.Simulation results verify  that the control principle and method more suitable for doubly-fed motor control system, can  effectively to dynamic control of motor speed, has good dynamic performance.The work  of  this paper  has the practical significance for the development of the double-fed motor speed control system , and laid the foundation of its system of doubly-fed motor further practical research .
