摘要
分析并建立了双馈异步发电机的数学模型;在分析双馈异步发电机有功功率、无功功率解耦控制的基础上,给出了基于定子磁场定向控制策略的实现方案;最后在STAR-90仿真支撑系统上对该控制方案进行了仿真实验。仿真实验结果表明,该控制策略能够有效地实现双馈异步发电机功率的解耦控制,对实际风电机组的运行具有参考意义。
The STAR-90 Simulation Support System was introduced in this paper firstly. The AC excitation variablespeed constant-frequency （VSCF） generation principle was secondly introduced. The mathematical model of doubly-fed induction generator was analyzed and established. The realization method of the stator flux oriented control was put forward based on analyzing the decouping control rules of the active and reactive power for the doubly-fed induction generation （DFIG）. At last the control strategy was simulated and tested on the STAR-90 Simulation Support System. Simulation and test results indicated that the control strategy can realize the decouping control of power for doubly-fed induction generator, which is reference value for the actual wind turbine group operation.
