In this paper, several scheme of vscf is compared firstly, of which gets doubly - fed generating mode. doubly - fed vscf wind power generating system uses a doubly - fed induction generator, which rotate speed can be able to change with wind turbine, and it ensures a constant - frequency output, by controlling the frequency of current input into rotor windings. in vector trans control system, the control of stator active power and the control of stator reactive power can be essentially decoupled, and the former is via torque component and the latter is via exciting component of stator current
本文首先比較了幾種變速恆頻方案，從中選擇了雙饋式變速恆頻方案；它運用雙饋電機的工作原理，允許發電機轉速變化，而在電機轉子側接入低頻勵磁電流，通過控制該電流的頻率，保證雙饋電機定子輸出的頻率恆定；再結合矢量控制技術，通過調節轉子電流來控制定子電流的轉矩分量和勵磁分量，相應獨立地控制發電機輸出的有功功率和無功功率。 -
There are five parts are as follows : in part one, the concept of switching function is introduced first to establish the nonlinear mathematical model of the induction motor variable frequency speed adjustment system which is fed by a sine pulse width modulated ( spwm ) inverter and takes the effect of the main magnetic circuit saturation into consideration, then the low frequency oscillation of the system is simulated according to the model. next, from the view point of energy conversion of the inverter - induction system, a criterion for the low frequency oscillation is proposed to determine whether the system is in low frequency oscillation which is judged by whether the interval of the negative current component of the inverter input current is more than 1 / fc ( fc is the carrier wave frequency of the inverter ) or not
首先引入開關函數概念，建立了正弦脈寬調制（ spwm ）逆變器供電異步電動機，考慮主磁路飽和時的變頻調速系統整體數學模型，模擬系統的低頻振蕩；其次從逆變器-異步電動機系統能量轉換角度出發，提出通過檢測逆變器輸入電流中負電流的間隔時間是否大於1 / f _ c （ f _ c為逆變器載波頻率）來判定系統是否出現低頻振蕩；最後的實驗結果驗證了系統低頻振蕩建模和判據的實用性和正確性。 -

矢量變換控制是以交流電動機的雙軸理論為依據，在同步旋轉坐標系中把定子電流矢量分解為兩個分量：一個分量與轉子磁鏈矢量重合，稱為勵磁電流分量；另一個分量與轉子磁鏈矢量垂直，稱為轉矩電流分量。 -
