摘要
推导了基于定子磁链定向空载并网数学模型,设计了双馈风力发电机并网控制系统,以TMS320F2812为控制器进行了发电机定子电压幅值、频率、相位、相序的有效控制。通过实验样机的并网实验,证明双馈发电机能够在不同转速下顺利、平稳地实现并网,从而验证了控制方法的正确性。
No - load grid - connection mathematical model based on stator flux - oriented and no - load grid - connection voltage control strategy were deduced, and grid - connection control system of doubly - fed wind power generator was designed. Amplitude, frequency, phase and phase - sequence of generator stator voltage were controlled effectively by TMS320F2812 controller. By grid -connection experiments of prototype, it was proved that doubly -fed generator could realize smoothly grid- connection at different speed ,therefore, correctness of control method was verified.
